» Application of Methods to Increase the Reliability of On-Line Data and Simulation Results for Regimes of Extractive, Main, Distribution Pipeline Systems

The urgency of the problem discussed in the article is due to the fact that at present Gazprom PJSC is implementing a modernization project for the Automated Dispatch Control System of the Unified Gas Supply System. Modernization provides for the complete automation of real-time parametric data collection systems (on-line data measurements) for which, in addition to deterministic estimates of parameter values, random (white noise), systematic errors (bias), abnormal emissions (peak values), partial loss or lack of data (communication channel failures), as well as errors due to the human factor (incorrect actions of personnel). Simultaneously with the process of automation of information flows, in the operating organizations and subdivisions of the subsidiaries of Gazprom PJSC, system support for dispatch solutions based on mathematical modeling of the regimes of gas producing, gas transmission and gas distribution technological systems are widely developed. At the same time, the quality and reliability of the solution of the system’ tasks are largely due to the completeness and quality of on-line data, the accuracy of mode calculations, the adequacy of models and the reliability of the results obtained on the basis of these models. The novelty of the proposed methods for solving this problem is due to the fact that the authors use modern mathematical methods of regression, disperse, multifactor analysis, methods of mathematical statistics, testing of statistical hypotheses, adaptation of computational models to actual regimes, and statistical criteria for assessing the adequacy of simulation results. This article touches upon only a small part of the problem and provides an overview of various approaches aimed at increasing the reliability of on-line data obtained by telemetry systems and the adequacy of on-line simulation results implemented in the Vesta on-line software complex.

Keywords: gas field, main gas pipeline, gas transport system, distribution pipeline system, modeling of modes, on-line data, mathematical method, adaptation, adequacy of simulation results.

» On-Line Data Adjustment of Meters in Trunk Gas Lines by Measurements of Operation Mode Parameters

Diagnostics by operation mode parameters is an effective method to assess equipment performance which, generally, does not require considerable investments, though still has not found its own level in maintenance of Unified gas transmission system units. The article suggests the efficient adjustment procedure for meters in main gas transport systems. The procedure is illustrated by the example of a twin gas main passage equipped with the latest instrumentation. The investigation used current measurements of regular instrumentation, studied pressure curves of all passage monitors. It was proved that at least several measurements contain systematic errors. To estimate them a procedure was suggested to minimize the functions of some variables in the presence of limitations. The metering algorithm was developed and the relevant error-handling routine created. Computations were carried out showing good model and actual data convergence. Thus, by the computing experiment the procedure efficiency was proved which requires no additional diagnostic devices and special tests to estimate systematic errors of instrumentation in the process of their operation. The algorithm proposed does not limit gas transport system configuration and can be applied both in stationary and unstable flow conditions of gas. The procedure efficiency is ensured by taking into account the whole set of operation-interrelated measurements of gas flow parameters. Processed and compared were the manometric survey data taken within the two a year distant periods. Dynamics of constant instrumentation errors fixed within this period allows to assess any changes in metrological equipment performance of a gas-transport company. The application of concepts and methods proposed are not limited to trunk gas lines and can be spread to other gas units.

Keywords: gas supply system, verification of measuring instruments, systematic error, parameter identification, theory of hydraulic circuits.

» The Test Case to Assess the Quality of Geological Simulation Packets

The system of functional tests has been proposed for quality assessment of program realization of mathematical algorithms used in software packages for geological simulation at principal modeling steps of oil and gas fields. These steps include, in particular, autocorrelation of logs, construction of surface frameworks for geological models, evaluation of hydrocarbon reserves, rescaling of log data to field-scale grids, construction of experimental variograms when analyzing spatial auto-correlation of various data, distribution of lithological, as well as porosity and permeability formation properties by deterministic and stochastic methods. The distinguishing feature of the test system proposed is availability of an exact solution for the problems under consideration which enables to assess the quality of their numerical solution results. The tests proposed have been proved in testing of computational modules of software complex “RN-Geosim” being a corporate simulator at Rosneft PJSC and in comparing of the data obtained with the problem solution results using the modern geological simulation packets Petrel and RMS.

Keywords: geological simulation, functional testing, numerical algorithm, software package for the geologic modeling.

» Operational Efficiency Estimate of Gas Air Coolers of New Generation

The article deals with the distinctive features of gas air-cooling apparatuses of new generation having found increasingly wide application in cooling systems of modern trunk gas lines. The estimate procedure of operational efficiency for new generation of apparatuses has been analyzed. As a criterion of efficiency estimate it was proposed to use a relative saving of energy expenses in terms of money for gas conveyance using modern apparatuses as compared to conventional ones. The criterion is based on the energy contribution to operating costs in the natural gas cooling system of the compressor station under review and in the comprimer system of the next station. Using the selected system integral criterion, the comparison of operational efficiency for the two types of modern air-cooling gas apparatuses – AVGB-75 and AVG-85MG with that of the 2ABG-75 air-cooling apparatus most widespread in the RF gas transport system, has been carried out. This comparison included a wide range of variations in operating characteristics of the multistrand gas main process section and ambient temperature. Based on the comparison results the operational efficiency estimate has been given for the gas air-cooling apparatuses of new generation and types under review installed in cooling systems of compressor stations of gas mains. The results obtained have been also compared with the expert evidences presented in the Gazprom PJSC catalogue of effective energy saving technologies in production, transportation and underground gas storage.

Keywords: modern equipment of the compressor station, new generation gas air cooler, natural gas air cooling system at the compression station, operating efficiency of the new generation gas air coolers.

» Current Analysis of Multi-Product Trunk Pipelines

The feature of multi-product or products pipeline operation is that a single pipe conveys several products different in composition. This technique is widely used for piping of light oil products, as well as some gas products piped in liquid state (e.g. wide light hydrocarbon fraction). Pumping is carried out by “direct contact”: each following product displaces a preceding one, and in turn, is displaced by the subsequent. Besides, mixing of products takes place in their contact zones and this process requires monitoring: the spread of the mixture formed is not the only thing one must know, its behavior with changes of pipeline lenght is also important. The article presented new algorithms which enable to compute the concentration of some components in oil-and-gas products in any multi-product pipeline passage. The scientific novelty of the procedure is that it allows to compute mixing of multi-component products using random initial distribution of each product concentration in the mixture, as well as to take into account multiple way injections of a product of arbitrary composition. The article gives final equations to design a multi-product pipeline and detailed description of the way these equations were derived. Besides it demonstrates the application of the proposed design procedure by the example of the pipeline for wide light hydrocarbon fraction in which composition of an injected product is variable due to way injections as well. Analytic data were used to construct graphs reflecting blend composition of wide light hydrocarbon fraction at the stations of pumping into the pipeline, and of way injections, as well as at the pipeline terminal enabling to compare product behavior in pumping visually.

Keywords: oil product, oil-products pipeline, products pipeline operation, gas product, wide light hydrocarbon fraction, way injections, mixing, concentration, blend composition, mathematical modeling.

» Enhancement of Gas Transmission Efficiency by Modeling a Mobile Compressor Station Operation

Transmission of gas using a mobile compressor station is a well-established technology widely applied by Gazprom PJSC in gas pipeline overhauling by the reinsulation method with partial or complete retubing. Major factors influencing the choice of mobile compressor stations are natural gas transmission efficiency and environmental friendliness. Therefore, the key criteria for the station efficiency assessment are gas transmission time and its optimization, as well as fuel supplied. The article presents the model to compute an optimal gas transmission time from a localized gas line section. The model accounts for the following factors affecting compressor station output: characteristics of a localized section and gas line planned for natural gas transfer, geometry of pipes, piston compressor parameters, thermodynamic gas properties. The computable model algorithm is given. Two graphs are presented: compressor output-inlet pressure, and transmission time-consumed fuel price (by the example of computations for Perm area, Russian Federation). The complex developed allows optimization of gas transfer conditions with selection of equipment characteristics, estimation of fuel consumption, selection of the equipment specified by Gazprom PJSC taking into account economic validity of its use, and gas transmission timing using available equipment.

Keywords: mobile compressor station, overhauling, modeling, methane, scavenge line, localized trunk line section, fuel, cost effectiveness.

» Optimization of Electrical Submersible Centrifugal Pumps Design

Operation of oil and gas fields in complicated environment requires the use of increasingly sophisticated deterministic designs for production equipment. As a result the cost of such equipment goes higher, as well as the expenses for its development, manufacture, testing, storage, service and maintenance. To cut the aggregate ownership cost for the oil producing equipment, including electrically driven vane pumping units, it is necessary to use a family of optimized standard sized equipment. Along with this, there should be provisions for the modification of every representative model of the standard sized equipment to ensure maximum efficiency of oil production under specific operating mode. Thus, the basic elements of electrically driven vane pumping units can be modified using a number of design and engineering techniques. But this requires the availability of science-based, economically feasible and legal assembling procedures of an electrically driven pump and the entire unit. The article presents some trends and assembling procedures related to the choice of stage types, manufacturing materials, designs of radial bearings, and the assembly type for electrically driven vane pumps. The article analyzes current designs for stages, radial bearings, and assembly types for pumps. It also gives optimal applications of various options for basic components and electrically driven vane pumps as a whole. The use of recommendations presented in the article for the assembling procedure will make it possible to increase oil production efficiency using electrically driven vane pumping units in complicated operating environment.

Keywords: electrical submersible centrifugal pump, design of stages, material of stages, bearing design, type of pump assembling, configuration of the pump.

» Basic Aspects of Overhaul of Compressor Stations Technological Pipelines

The article handles optimal planning problems related to overhauling of industrial pipelines in compressor stations, including the methods of preferred overhauling, and the analysis of experience gained in executing of 2009–2018 works. In accordance with clause 7.2.1 of company standard (STO) Gazprom 2-3.5-454–2010 “Service instructions for trunk gas lines” the aim of exploitative organizations is to ensure a stated gas comprimer rate and efficient operation of compressor stations along with reliability and safe operation of their equipment and systems. As underground industrial pipelines of most compressor stations are in operation of over 20 years, Federal law dated 21.07.1997 No. 116-FS “On industrial safety of hazardous manufacturing entities” requires to expertise industrial safety of equipment and implement compensating measures prescribed by the expertise limiting manufacturing capabilities of compressor shops. Creation of the integrated maintenance programme for industrial pipelines and its ranking provides for aggregation of full information on pipelines status considering various criteria while absolute meeting of requirements for equipment reliable and safety operation. To obtain an objective evaluation of industrial pipeline technical state a master plan for technical diagnosis and maintenance of underground pipelines using various economically feasible methods is under development and implementation. Utilization of know-how allows to define most preferred ways of overhauling engineering from designing to implementation of the works which ensure cost optimization for material and technical basis, as well as construction and assembling operations.

» Modernization of Underwater Pipeline Maintenance Complex to carry out Chemical Dispersion

The article deals with the renovation problem of underwater pipeline maintenance complex to use it for underwater dispersion when cleaning oil spills resulting from accidents in underwater wells and pipelines. The article describes the design features of the Russian development – “Tulpar” maintenance complex, which allow its application for underwater dispersion. These include front and back locating grip, as well as a hybrid unit for pipe washing and cleaning able simultaneously move forward and rotate. The features allow to perform precise location of the submersible unit on the accident site and also deliver a despersion reagent exactly to the point of oil spills under video-camera control. The article suggests the engineering solution which allows application of the hydraulic system for the maintenance complex to deliver a despergent both from the surface, from the service vessel, and from the underwater tank. It is achieved by the hydraulically controlled on-off submersible unit disperser. The article describes line coupling of the disperser and possible supply of the composite solution when carrying out underwater pipeline maintenance operations by installation of the protection sleeve, encapsulant and dispergent if cleaning of oil spills due to the accident is required. The concept of developers provides design modularity. The changes proposed will make it possible to have complexes for underwater dispersion and prompt repair of underwater pipelines of different sizes located at any depth and to use them for other underwater production projects.

Keywords: repair of underwater pipelines, a complex for underwater pipeline repair, chemical dispersion, underwater dispersion, dispersant, underwater pipeline, oil, spill.
