» Justification of choice of the technical means of automation for safety systems

The paper deals with the design of the technical means of automation (TMA) for industrial safety systems, in particular emergency shutdown systems (ESS). The article analyzes the scientific literature and technical documentation in the field of industrial safety and automation of the process control system. The scientific and technical documentation has requires to indicators of reliability of technical means of automation, which are part of the safety system (SS), but these requirements are defined on an interval scale, and not specific enough. Due to the lack of clarity of the existing performance requirements of reliability it is necessary to develop a methodical basis to justify the selection of the automation system safety technical means that takes into account the required safety integrity level facility, the requirements of scientific and technical documentation, reliability of technological devices, technical and economic parameters of procedures implementation and maintenance of automation hardware. The paper presents a conceptual framework for solving this problem and methods of implementation the automatic protection circuit technological equipment. The idea of the method consists in the fact that from a variety of software and hardware of the SS, on which you can build circuits automatic protection, select system, for which the probability of failure (or uptime) regulatory requirements and, in addition, low costs of implementation and maintenance. The example of use of the developed methodology in selecting SS capacity in one of the processing units is did. Based on these results it is concluded that the proposed method enables the choice of the hardware part of security systems to meet the scientific and technical documentation requirements for the reliability indicators of devices, performance and reliability the technical and economic efficiency of the implementation and maintenance the automation hardware. This technique allows you to take into account the preferences of the customer in selecting the manufacturer if they are submitted in the technical specifications for the design.

» Choice of PDC bits in accordance with hardness and abrasion of the formations

Diamond cutting-chipping bits (PDC bits) find all more broad using when boring the bore holes on oil and gas. The bit for drilling concrete interval of the formations must conform to their hardness and abrasion. The problem of the bit choice is probabilistic because mechanical characteristics of the formations change in more broad limits. The level of significance (risk) is assumed equal to 2.5%. Solution of the design choice of cutting structure bits obtained by the example of the bits produced by Burintekh, Ltd. In the recommendations of the enterprise of bits applications are given the ranges of hardness and abrasiveness of rocks in the categories. In these recommendations there is a dependence the numbers of blades drill bits both from the hardness and abrasiveness of rocks. But for a bit different designs their applications overlap, making it difficult bits clear choice when designing drilling mode. The authors of article proposed two nomograms to choice PDC in accordance with the statistical characteristics of rocks drilling interval. By first nomogram, bits are selected in accordance with the hardness, and by the second nomogram bit is specified in accordance with the abrasiveness of rock. The article presents a numerical example of the use of nomograms, according to the properties of rocks on area Priobskaya in West Siberia. The choice on the nomogram was compared with the actually used bit designs on this area. The results of the comparison showed that selected by nomograms bits coincide with the most effective of the used bits.

Keywords: PDC bits, hardness and abrasion of formations, nomogram, drilling mode, choice of bit.

» Main problems of energy saving in the pipeline transport and their solution lines

Main energy consumption in the pipeline transport of oil and oil products is associated with operation of main pump units. Electric power consumed by main pump units can be represented as follows: power losses in control systems (at the gate valve, control unit piping, etc.), hydraulic power (consumed to overcome losses, for friction and elevation differences), power losses in the pump and drive elements (frequency transducer, etc.). In the current conditions, the greatest practical interest lies in the comprehensive rather than in local approach towards electric power saving issues. Analysis of practical experience and literature demonstrated that the following additional researches shall be done to improve current energy results: determination of the conditions when it is reasonable to use a certain method of smooth pressure control; determination of compliance with the requirements set forth in the regulatory documents concerning frequency of pipeline cleaning in practice and search for the possibilities to further reduce energy expenses due to additional cleaning; determination of the conditions when it is economically feasible to use the turbulence control additive in case of pressure control with the frequency transducer. Analysis of the effective international and Russian regulatory documents related to energy saving carried out in this paper, demonstrated that these documents do not contain express practical activities and rather determine only the necessity to develop and implement such activities.To comply with the requirements set forth in the Federal laws and regulatory documents related to energy saving, Transneft JSC developed and uses the energy saving program, but it does not touch upon the foregoing difficult issues, which confirms that they are relevant and that researches in this line shall be performed.

Keywords: energy saving, pump, turbulence control additive, reduction.

» Resource saving technology of the main gas pipeline section shutdown for repair with gas generation by the compressor station for GPU and consumer via gas distribution plant

The Russian Federation is the only large industrially advanced country that completely provides fuel and energy for it self due to own natural resources and exports fuel and electric power at the same time. Natural gas is the main energy carrier. Dynamic development of the country's sectors of the national economy is impossible without natural gas. The fields of this natural resource are foremost located in the Russian northern regions; therefore it has to be transported for many thousands of kilometers to be delivered to the central regions and foreign partners. The main method of the energy carrier transportation is the pipeline transport that proved itself as the least costly method. Energy efficient management of gas main transport is one of the priority lines of stable development and costs optimization in the gas industry. The gas transportation enterprises of Gazprom JSC currently pay serious attention to the problems associated with sustainable use of natural gas for own process needs complying with the requirements for industrial safety and optimal management of the gas transportation system, as well as to the issues associated with reliable assessment and forecast of gas transportation modes during operational control taking into account the equipment actual technical condition. Gazprom JSC consistently implements the policy of energy and resource saving, mitigation of adverse environmental effects and increase in production processes energy efficiency. The paper proposes the resource saving technology implying preliminary generation of natural gas for compressor stations and consumer via gas distribution plants (GDP) from a large diameter gas pipeline section shut down for repair. The technology can be used to solve the problems of energy saving production dispatch management and energy efficient management of main gas pipelines gas transportation system.

Keywords: gas distribution plant, operation, optimization, compressor station, gas pipeline, energy saving, energy efficiency, environmental efficiency.

» A new approach to selection of enhanced oil recovery methods on the basis of the fuzzy logics and Bayesian inference mechanisms

Currently, the procedure for selecting the enhanced oil recovery methods (EORM) when designing the oil fields development represents the procedure that is not formalized in full. At the same time, selection of the best available technology of enhanced oil recovery for certain geological, physical and economic conditions of the development is one of the most complicated tasks for development engineers. Informative review of the history, present and prospects for development of EORM studies is provided by Taber, who also proposed the tables known in literature as Taber tables. However, the Taber's approach does not allow performing a mathematically strict ranking of EORM by extent of their applicability for certain field. This paper proposes the approach to EORM selection on the basis of a fuzzy logics, possibility theory and Bayesian inference mechanisms. The methods are ranked by each criterion parameter by marking the best method for this parameter applying rules for fuzzy interval comparison. The results obtained after assessing the extent of applicability of each EORM are specified with the use of the summarized interval Bayesian inference mechanisms.Applying this method for physical and geological conditions of the Albert field allowed selecting EORM in a more correct way confirming the reliability and practicality of the proposed approach. Simple calculation procedure (no more than five iterations) allows computerizing the process of selecting the most acceptable EORM for a certain field.

Keywords: applicability coefficient, EORM ranking, screening criteria, fuzzy interval, Bayesian inference procedure.

» The study of the influence of ultrasonic pulsed radiation at threaded connection tubing

Firm tight connection of pipes is ensured by significant forces of friction in the threaded connection. To reduce wear of threaded connections it is required to reduce friction in matched screw pairs directly during screwing-unscrewing. Results of pulsed acoustic effect in quasi-continuous operation on the threaded connection of tubing are presented. Four pulse magnetostrictive emitters АIFP 0.7-22 and waveguide-clamp for emission input at the angle of 90о were used in experiments for acoustic effect on tubing. Used equipment is a production and laboratory kit allowing for obtaining the four-point multi-frequency ultrasonic field with phase control. Parameters of ultrasonic vibrations, such as capacity, frequency, amplitude, angle of vibration input, have a significant impact on the tubing unscrewing process efficiency with ultrasound. To assess the pulse acoustic effect on the tubing threaded connection at various types of acoustic forms of vibration in the pipe and in the threaded connection area, the complex was used including: high frequency vibration inverter АR31 (frequency range – up to 20 kHz) with amplifier А5000 and power supply АR01, SpectraPLUS software package. When performing works, acoustic rapid analysis of wave properties of NKT-73 tubing was performed, in the result optimal parameters for the ultrasonic generator setting were determined and the value of ordinate dimension between the excitation plane of longitudinal ultrasonic wave and the area of target effect – threaded connection, was determined. An important feature of this method is opposite-consecutive operation of emitters.

Keywords: threaded connection, ultrasound, coupler, waveguide emitter, friction, frequency, amplitude, vibration sensor.

» Definition of optimal parameters in artificial neuron network for gas processing plant model calculation by HYSYS

For operative correction of the complex gas treatment plant operation mode, performance of similar calculations of material balances of raw hydrocarbon deposits routine processing of gas condensate and oil and gas condensate fields, calculation of compositions and characteristics of routine processing products – commercial gas and unstable condensate – it is convenient to use process simulation systems (such as HYSYS). At the same time, primary setting of the model is highly labour consuming and requires high quality source data. However, in the future, for these tasks resolving, the model hardly needs additional setting and adjustment, and can return precise results upon insignificant variations of input parameters. For this reason the authors attempted to use a tool of artificial neural networks creation integrated with HYSYS, for making forecasts of complex gas treatment plant operation in the conditions of changing input parameters. The principle of creating an artificial neural network in HYSYS process simulation system is reviewed on the basis of the complex gas treatment model. When creating artificial neural networks that describe the complex gas treatment plant model, six main parameters were used. Neural networks were created with training bases of various sizes (from two to five levels for each parameter). As a result, training bases had from 64 to 15,625 reference points. Created neural networks calculation accuracy and accuracy of calculation performed on thermodynamical model of the complex gas treatment plant in HYSYS were compared. Analysis of the calculation results allowed for determination of the reference points optimal amount required for the neural network creation describing operation of the complex gas treatment plant model with low-temperature separator with adequate accuracy.

» Energotechnological complex on the basis of expander-generator machinery at the compressor station

Currently at compressor stations fuel gas for the gas compressor unit is taken from the main gas pipeline at the inlet to the compressor station with pressure of 4.5–6.5 MPa. Further it is cleaned and flashed to pressure of 1.5–2.5 MPa prior to supply to the combustion chamber. If required, the fuel gas is heated. This fuel gas recovery scheme at the compressor station can be extended with an expander-generator machine in order to use the energy of excessive gas pressure, replacing the flashing process with expansion. In case of adiabatic gas expansion in the expander the flow enthalpy does not change, but internal energy and, consequently, temperature are reduced. Excessive pressure energy transforms into mechanical energy in the expander, and further transforms into electric power generated at the power generator shaft.Two useful flows can be obtained: 1) electric power generated in the expander-generator machine, 2) flow of gas cooled in the expander-generator machine. In the process of gas compression its temperature rises, and it negatively affects the gas transportation efficiency. In order to stop continuous gas heating as it is being transported through the main gas pipeline, gas cooling after compression is provided for in the compressor shop flow-chart. Usually gas is cooled in air coolers, which spend a significant amount of electric power for the ventilators drive. It is proposed to cool part of the compressed gas with a flow of cooled fuel gas downstream expander, allowing saving of electric power for air coolers and use heat power sources of the natural gas compressor efficiently. This paper evaluates energy efficiency of the recovery scheme of the fuel gas excessive gas pressure energy and obtained cool flow at compressor stations.

Keywords: expander-generator machine, compressor station, excessive pressure energy, energy saving, gas turbine plants (GTP), air coolers, secondary energy sources (SES).

» Compressor station efficient operation implementation in compliance with man-made facilities industrial safety principles

Energy saving concept implementation in the gas industry has shown that one of the most efficient ways to reduce the energy costs with the main transportation of natural gas is to optimize Gas Pumping Units (GPU) at Compressor Stations (CS) operating modes. This task solving includes the identifying the efficient operating modes of gas-turbine units - the main GPU power drive type. Main Gas Pipeline (MGP) CS compression system assessment is generally carried out by comparing the value of the used optimization criterion at the gas compressor equipment efficient operating modes with the value of this criterion at the optimum operating mode. Optimization criterion selection relevance largely determines the assessment correctness of compression systems energy efficiency. Currently, a number of criteria such as the fuel gas and electric power cost in physical terms, the total GPU power drive performance, polytropic performance coefficient value of compression process and the provided effective power drive performance coefficient in compression system and etc are used as the local criteria of MGP CS compression system optimization. Developed algorithm allows optimizing the centrifugal compressors speed in terms of equal load of all units involved in gas compression process. This will increase the total polytropic performance coefficient. Calculation of results based on the proposed method showed the real opportunity to improve the compressor station efficiency in line with man-made facilities industrial safety principles observance by means of increasing the total polytropic efficiency.

Keywords: gas pumping units, compression systems, compression rate, regulation, operating mode optimization of gas pumping
units.

» Theory and calculation method of surge reduction systems

The article deals with modeling of pipeline surge relief systems (PSRS) designed for protection of main pipelines (MP) sections from disruptive impact of high pressure surges. Such surges can occur in the oil pipeline due to various process operations accompanied by sharp stagnation of transported oil flow caused, first of all, by a sudden trip of the oil pumping station (OPS). Should some pumping units of OPS or the whole station stop, a surge of increased pressure is formed at the section of pipeline, preceding this station, and spreads upstream of the oil flow to the preceding OPS. Value of pressure in the spreading surge can significantly increase the bearing capacity of pipeline and lead to various negative consequences, from trip of pumping station, located upstream, to cascade tripping of OPS or loss of pipelines integrity and inevitable oil seep to the environment. In addition, speed of the automated control system installed at each oil pumping station may appear to be insufficient to operate correctly when a sharp pressure front comes, and this can also lead to tripping of pumps at the relevant station. Unlike the safety valves that ensure partial removal of transported fluid in case pressure exceeds the maximum allowable value, the surge relief systems mainly react to the speed of pressure increasing and ensure partial removal of oil to a special tank only in cases when the speed exceeds specific allowable value. The article deals with PSRS theory, modeling of PSRS operation, mathematical calculation method, principles of PSRS parameters setting, and gives illustrations.

Keywords: pipeline, pressure reduction system, hydraulic shock, gas accumulator, relief valve, mathematical modelling, method
of characteristics.

» Development of multifunction composition and technology of killing and washing out of the paraffin deposits in the wells with abnormal low reservoir pressure

The article shows the urgency of the problem of formation and removal of paraffin deposits in the wells with abnormally low reservoir pressure. The use of aqueous saline washing fluids in the wells with a low formation pressure fails to achieve effective flushing of deposits due to their high filtering into the formation. The presented solution to the problem is to develop multi-functional polysaccharide non-filtering well killing and washing fluid. The basic stages of the composition development are: the choice of surfactant characterized by an effective dispersing, wetting and washing abilities to the deposits studied in the work; the choice of hydrocarbon solvents characterized by a high dispersing, dissolving and washing abilities to the paraffin deposits of different types studied in the work; the development of the process fluid for well killing and washing the wells on the basis of the obtained data and complex technology of washing the wells. The process fluid was developed on the base of the polysaccharide well killing fluid composition characterized by low filtration loss, controlled density within a wide range, but does not possess the washing ability out of the paraffin deposit. The use of a specially selected surfactant and a mixture of hydrocarbon solvents of different nature, helped to achieve the process fluid characterized not only by the positive filtration characteristics, but also by effective washing ability out of the paraffin of various types. The developed process fluid would solve the problem of the circulation lack during the washing the wells out of the paraffin deposits in the wells with abnormally low reservoir pressure and its high washing ability would help to achieve the efficient removal of deposits.

Keywords: well-killing fluid, asphalt-resin-paraffin deposition, abnormally low reservoir pressure, surfactants, hydrocarbon
solvent.
