METHOD FOR DEVELOPMENT OF HYDROCARBON FLUID DEPOSITS

FIELD: mining.SUBSTANCE: invention relates to mining. High-viscosity oil or bitumens deposits development method involves drilling of horizontal wells, drilling of horizontal injection wells above them, pumping of heat carrier through injection wells, product extraction through horizontal production wells. At that, production and injection wells are made multi-shaft with identical number of shafts in accordance with number of developed productive formations, wherein shafts are made with horizontal sections in productive formations, located parallel to each other in one direction. Wells horizontal boreholes are uniformly perforated, wells are equipped with temperature and pressure monitoring devices. Injection well shafts are equipped with packers. Through injection well shaft inter-packer section performing pumping of inert heated working fluid into productive formations, heating productive formation to in-situ hydrocarbon fluid self-ignition temperature, performing inert working agent replacement with oxygen-containing working agent, by pumping which hydrocarbon fluid into formation is ignited. Tracking and keeping of combustion front in productive formation maintaining and propagation conditions, heating limited by packers section of formation to state of hydrocarbon fluid fluidity and performing heated product extraction, and formation temperature maintaining within limits providing fluid flow is performed by changing of oxygen-containing working agent injection volume. After complete exhaustion of productive formation zone in inter-packer section injection of oxygen containing working agent is temporarily stopped, pipe string with holes and two limiting packers is moved towards injection well mouth for not less than length of distance between packers, packers are brought to working state and development of next area of productive stratum is continued, thus whole horizontal section of injection well is developed.EFFECT: increasing efficiency of fluid extraction process from multi-formation deposits of high viscous hydrocarbon energy sources, increasing intensity and completeness of hydrocarbon energy sources extraction.1 cl, 1 dwg, 1 ex Изобретение относится к области горного дела.
