PROCESS OF DEVELOPMENT OF OIL FIELD Russian patent published in 2002 - IPC

FIELD: oil industry, development of oil field constructed intricately. SUBSTANCE: in process of development of oil field oil is recovered through production wells and working fluid is pumped through injection wells. Direction of zone of maximum jointing formed in collector in process of well development is exposed. Direction of jointing being exposed fluid with indicator is injected and time of travel of indicator and volume of fluid needed for its delivery from injection wells to production wells in washed-through part of pool are found. Then grouting mortar in the amount corresponding to volume of fluid pumped for delivery of indicator is pumped under pressure 2 to 10% higher than working pressure of injection. Later new rows of injection wells from number of flooded production wells are formed with their arrangement in parallel to direction of zone of maximum jointing. In process of further development of oil field working fluid is pumped under pressure across face of injection wells below pressure of opening of cracks. EFFECT: increased recovery of oil from field.
