FIELD: recovery of additional hydrocarbons from deposit. SUBSTANCE: in process of development of hydrocarbon deposit hydrocarbons are extracted through production wells. Dominant frequencies of source of vibration-seismic action are determined for two pairs of neighboring wells by appearance of hydrocarbons of higher viscosity/or density as compared with hydrocarbons recovered before from given deposit. Zones of recovery of hydrocarbons and zones of injection of working fluid are formed on deposit. Present formation pressure and pressure differentials between interlayers caused by injection and recovery are established. Vibration-seismic action on deposit is predominantly executed in points of pressure differentials of formation pressure with dominant frequency within bounds of determined dominant frequencies. Deposit is developed with employment of barocyclic action. EFFECT: raised output of hydrocarbons thanks to restoration of mobility of viscous component. |
