FIELD: oil production industry. SUBSTANCE: this can be used in development of oil deposit at later stage. According to method, oil is taken through producing wells. Burning of oil bed is initiated in injection wells and air is injected. After taking-out of 75-80% of available reserve, pumped into injection wells is accompanying Devonian water with density of 1.06-1.09 g/cm3 at average yearly volume of outputs from producing wells at down-hole pressure in producing wells not below 0.6 of initial bed pressure. Injection of accompanying Devonian water is effected in cyclic duty: during 5-7 months - injection, another 5-7 months - stoppage. In injection, additional cyclic mode is carried out: 10-20 days - injection, another 10-20 days - stoppage. EFFECT: high efficiency. |
