| 摘 要： | 驱油效率是预测油田最终采收率、评价油田开发效果的主要参数。以双河油田资料为基础，建立了驱油效率与渗透率、油水粘度比和注入倍数的关系式。该多元回归式不仅可确定最终驱油效率，而且还可计算注水倍数，确定不同开发阶段的驱油效率、波及系数。驱油效率实际值与预测值平均相对误差8．7％，精度满足生产要求。

| Abstract: | According to development data of Shuanghe oil field,this paper builds the multivariate regression relational expression.Using the relational expression can calculate not only oil displacement efficiency but also water injection times and waterflood sweep effciency. The relative average error between predicted oil displacement efficiency and actual value is 8.7%, the accuracy meets demand of production. |
