PROCESS OF EXPLOITATION OF MULTIPOOL OIL DEPOSIT Russian patent published in 2001 - IPC

FIELD: oil industry. SUBSTANCE: pools are divided according to invention into two groups. Pools with highest penetrability are included into first group. Second group includes less penetrable pools. Oil is extracted from pools through production wells. Working fluid is pumped though injection wells. If penetrability of pools differs by factor of 10 and more, that is, when superpenetrable pool called supercollector exists in deposit injection wells sunk into pools of second group are shut down. Injection wells are sunk directly into supercollector and/or injection wells drilled into supercollector are used. Hydrodynamic direct connection of production wells to supercollector is liquidated and additional production wells are sunk above supercollector. Working fluid is pumped into supercollector through injection wells. Oil is extracted through production wells arranged above supercollector. EFFECT: enhanced output of oil. 1 cl
