摘要: 驱油效率是注水开发油 田的一个重要指标,目前都由实验室水驱岩心实验得到。实验室测定的只是最终水驱油效率,不能用来描述开发过程中的相关状况。根据水驱油藏特征,在丙型水驱曲线的基础上,详细推导了利用油田地质参数和生产历史数据预测注水开发油田驱油效率的公式。双河油田某开发层系的实例研究表明,这里提出的方法在油田开发效果评价中有一定的应用价值,同时具有形式简练、易于计算和结果可信的特点。

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
