FIELD: oil production industry. SUBSTANCE: this can be used in development of structurally complex deposit. According to method, selected in deposit is section limited by deep concavity of oil bed and lithological replacement for non-reservoir. Arranged in selected section are producing wells and oil is taken in natural mode. Injection wells are located along deep concavity of oil bed, and additional producing wells are located in dense net. Deposit is developed in mode of maintaining reservoir pressure. At 60-70% extraction of reserve in selected section, flooded producing wells are converted into injection wells, and formed are fronts of displacement along zone of lithological replacement of bed for non-reservoir. EFFECT: high efficiency. |
