PROCESS OF EXPLOITATION OF OIL FIELD Russian patent published in 2001 - IPC

Abstract RU 2165521 C1

FIELD: oil industry. SUBSTANCE: invention refers to exploitation of oil fields presented by oil pool with dam made of dense rocks and water-bearing pool and is directed for additional extraction of oil from depression zones. When oil field with oil pools having dams of dense rock and water-bearing pool is exploited pool is flooded through injection wells. Oil is extracted to surface through production wells. Inflow of water to production wells is insulated. Outlines of positions of dams of small thickness are established by geophysical investigation prior to conducting of insulation operation. Then water impermeable screens are set over entire outline through open shafts of wells in these zones to height of decrease of thickness of dams in water-bearing pools before their grouting. EFFECT: prolonged time of exploitation of wells up to their ultimate flooding by installation of water impermeable screens in constructed wells. 1 dwg
