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

FIELD: mining.

SUBSTANCE: invention relates to mining. Method of developing deposits of hydrocarbon fluids includes construction of a extraction horizontal well in field of productive rock layer, construction of horizontal injection wells over extraction horizontal well in same direction at an experimentally determined distance from extraction horizontal wells, injecting coolant into injection well and selection of formation of product from production well. Method includes drilling horizontal injection well with two parallel shafts, in first shaft of injection well pipe string is lowered with plugged end and made on end section of holes for pumping of working agents, pipe section with holes at both ends is limited by packers, heated working fluid is pumped to productive formation, productive formation is heated to self-ignition temperature of in-situ hydrocarbon fluid is replaced by inert working agent on oxygen-containing working agent said hydrocarbon fluid in formation, controlling and maintaining condition of storage and propagation of combustion front, heated formation between wells. In area of horizontal section of production well adjusted section temperature to yield state of temperature of hydrocarbon fluid and produce a selection of heated product, in this case with use of temperature and pressure monitoring devices monitor intensity of process of combustion and heating of reservoir in inter-well and surrounding space, and maintenance of reservoir temperature in necessary framework is carried out by changing feed rate of oxygen-containing working agent. After complete production of zone producing formation within first step installation of packers pumping of working agents is temporarily stopped, moving pipe with holes and with two limiting packers towards mouth of production well by not less than distance between packers, packers are brought into operation and continued refinement of following producing formation zone, working through entire horizontal portion of bottom-hole zones of two horizontal wells injection well.

EFFECT: technical result is increasing effectiveness of fluid extraction from fluid-bearing reservoir rock and increase in hydrocarbon fuel production.
