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

FIELD: oil production industry. SUBSTANCE: in agreement with proposed process pools are divided into two groups. Average values of filtration-capacitive properties are estimated per each group. Pools with highest penetrability and advanced working of stock are included into first group. Second group of pools includes less penetrable pools with slow working of stock. Oil is extracted from pools through production wells and working fluid is pumped through injection wells. If penetrability of pools differs by factor of 10 and more, that is, there exists superpenetrable pool- supercollector, production wells are drilled directly into this supercollector and/or wells drilled in supercollector are used as production wells. Injection wells are drilled above supercollector. Gaseous agent is pumped as working fluid through injection wells. EFFECT: raised oil output of deposit. 1 cl
