RESEARCH AND APPLICATION OF IMPROVING OIL DISPLACEMENT EFFICIENCY BY WATERFLOODING DEVELOPMENT HETEROGENEOUS RESERVOIR

Yan Fan

Abstract

Using water flooding technology in intermediate zone,minute-fracture pressure water injection and profile control etc.technique carry out rational water flooding,can reach the goal of systematical development heterogeneous reservoir and make degree of water-drive and oil displacement efficiency of low ooze layer improve,formation pressure and productivity of correspondnece oil well increase.Through field application of the water injection oil displacement technique in Qiaokou Oilfield,the results show that the technology can slow down effectively natural lapse of oilfield and keep stable production and high production of oilfield.
