FIELD: oil industry.
SUBSTANCE: inventions group relates to the oil industry, and in particular the production of hard-to-recover reserves of hydrocarbon fluids - oil and gas condensate using gas. According to the method for developing hydrocarbon deposits by cyclic gas injection, the threshold value of the gas factor is determined, after which the gas factor increases with a decrease in the flow rate of the hydrocarbon fluid. The threshold value of the gas flow rate injected into the well is determined, at which the transition to the stationary filtration process is provided. The holding time of the well, sufficient for effective gas dissolution is determined. The development of a hydrocarbon deposit is carried out, each cycle of which includes the production of a hydrocarbon fluid from at least one well to a threshold value of the gas factor. Gas is injected into the same well up to the threshold value of the gas flow rate. Maintain the well for a time sufficient for effective gas dissolution.
EFFECT: invention increases oil recovery of oil reservoirs by cyclic gas injection.
