摘要(Abstract):

聚合物驱油技术是继水驱后开发老油田有效驱替方式之一。为了进一步提高聚合物驱增油效率,通过多元线性回归方程,结合聚合物驱替特征曲线法和经验回归方法推导出了聚合物驱不同阶段产油量预测公式,简化聚合物驱油方案设计,对油田稳产具有一定意义。
Polymer oil flooding technique is one of the effective displacing methods for the mature oilfields after the water flooding.In order to further enhance the displaced efficiency,with the help of multivariate linear regression equation and integrating with the polymer flooding characteristics curve and empirical regression methods,the predicting formulae for different development phases of the polymer flooding are derivated,and furthermore the polymer flooding scheme design is simplified.In a word,these achievements possess a certain significance for the oilfield stable production.
