Forecasting Displacement Efficiency with Performance Data in Water Drive Oilfield

Abstract

Abstract: Oil displacement ffciency is a sigmificant index in water drive oilfeld, and is uually abtained by water drive cores experiments. In laboratory, only the ulimate oil displacement ffciency may be measured and it could not be applied for evaluating oil development eficiency. According to the characteristics of water drive reservoir, this paper deliberately deduce the method of applying goological parameters and production history data to forecast the oil displacement eficiency, based on the third water drive curve. The case study of a development sequence in Shuanghe oilfield has indicated that this expression is applicable and effective in evaluation of oil development fficiency. Meanwhile, it features the form conciseness, easy calculating and high credibility.

Key words: oil displacement fficiency, water drive, development effectiveness, caleulation
