Practice of Injection-production Adjustments of Low Permeability Reservoirs in Pingbei Area of Ansai Oilfield

LI Min-yong

Abstract

The main methods to ensure continuous stable production in Ansai Oilfield from 2001 to 2005:1.to enhance wate drive controlling by improving injection-production patterns uninterruptedly;2.to increase the availability of injected water by developing separate water injection;3.to increase the development effect of water injection by several methods;4.to increase the efficiency of water drive by adjusting injection-production series of strata reasonably.
