iNVESTIGATION OF HYDROCARBON GELS based on ORGANIC orthoPHOSPHORIC ETHER IRON SALTs APPLIED FOR carbonate RESERVOIR selective ACIDizing TECHNOLOGY
L. Magadova, M. Silin, V. Magadov, D. Malkin, V. Dyachenko, V. Ponomareva, Gubkin Russian State University of Oil and Gas Hydrochloric acid treatments of carbonate sediments are widely used in development practice for well performance stimulation. Efficiency of such treatments is not high enough due to formation damage caused by sediments and emulsions produced after interaction of hydraulic acid and highly resin and asphaltene saturated oils. Use of developed hydrocarbon gel based on gelling complex “Himeko-N” and diesel fuel during selective acidizing helps to create water shut-off screen. This happens due to reservoir surface modification with hydrocarbon gel decomposition products. Keywords: oil recovery intensification, hydrocarbon gel, interfacial tension, slowing down the reaction between the acid and the rock, waterproofing screen.
