METHOD FOR DEVELOPMENT OF HIGH-VISCOUS OIL AND BITUMEN DEPOSITS

摘要

FIELD: oil production industry. SUBSTANCE: method implies extraction of viscous and high-viscous petrobitumens by heating reservoir with high-frequency electric current. Procedure is as follows. Drilled out are at least three wells with vertical and horizontal sections of bore-holes directed parallel to each other. Installed into extreme wells are electrodes, and installed into intermediate well is reversible electric centrifugal pump. After heating of oil bed, heated product of intermediate well is directed into part of bed not covered by electric field with subsequent pumping-out of heated oil to day surface by reversing operation of pump. EFFECT: high efficiency. 2 dwg
