PROCESS OF EXPLOITATION OF MULTIPOOL OIL DEPOSIT Russian patent published in 1996 - IPC

FIELD: oil production. SUBSTANCE: process provides for drilling-out of deposit by system of vertical injection and horizontal production wells with selection of their trajectory and opening of all pool of multipool oil deposit, driving of oil with working agent and extraction of products. Selection of trajectory of horizontal wells is carried out by connection of points positioned over uniform grids inter matched in plane which number is equal to number of used pools. Start of horizontal shaft in row of wells bordering on rows of injection wells is placed at distance bigger than distance from its finish to injection well. Center and finish of horizontal shaft is arranged at equal distances from injection well. As extracted products are flooded sections of well shafts are disconnected by pumping of polymer solution in calculated volume beforehand and of plugging material later. EFFECT: improved operational efficiency of process. 1 dwg, 1 tbl
