METHOD FOR DEVELOPMENT OF HYDROCARBON FLUID DEPOSITS Russian patent published in 2016 - IPC E21B43/243 

FIELD: mining.

SUBSTANCE: invention relates to mining. In method of development of deposit of hydrocarbon fluids in productive layer above its bottom on experimentally determined distance from each other double-head horizontal production wells are drilled, between double-head horizontal production wells double-head horizontal injection well is constructed in the same direction, into mentioned injection well from two heads two pipe strings are lowered with plugged ends and holes made on end sections for pumping of working agents, produced formation section is limited by packers on two ends. Via pipe strings in injection well heated working fluid is pumped into productive formation. Productive formation is heated to self-ignition temperature of in-situ hydrocarbon fluid. Inert working agent is replaced by oxygen-containing working agent, igniting hydrocarbon fluid in the formation. Monitoring and maintaining combustion front propagation in formation formation section temperature is driven to yield temperature of hydrocarbon fluid and heated fluid is taken to the complete exhaustion of productive formation section within the first step of packers installation. Then pumping of oxygen-containing working agent is temporarily stopped, isolating composition is pumped in the worked-out section of productive formation for prevention of premature breakthrough of oxygen-containing agent to production wells bottoms. Then pipe strings with holes and limiting packers are moved towards the head of injection well for no less than distance between packers. Packers are brought into working position and the next section of productive formation development ic continued. All productive formation is worked out, wherein maintainance of formation temperature is performed by regulating flow of oxygen-containing working agent.

EFFECT: technical result - increase of efficiency and effectiveness of the process of fluid development from fluid formation.
