聚合物驱转后续水驱时机和方法

Timing and Methods of Injectioning Polymer to Injection Water

以往注聚区块转后续水驱技术政策并没有规范,也没有深入的研究,转后续水驱的时机和方法各不相同;部分区块转后续过早,导致停注聚后含水上升过快,转后续水驱过晚聚合物成本高、经济效益差。该文对以往转后续水驱区块停注聚效果进行对比分析,得出转后续水驱的最佳时机,又根据以往转后续水驱积累的经验,总结出了停注聚的方法。

The technology and policy of injectioning the polymer to injection water is no standard in the previous polymer injection block, no in-depth study as well.there are differences in the timing and methods of injectioning the polymer to injection water.Turning to injection water too early in some blocks will lead to the rate of water rising too fast.turning to injection water too early too late will lead to the higher cost of polymers and the poorer economic benefit .The effects of injectioning the polymer turning to injection water in the previous polymer injection block make comparative analysis in this article.Thus we obtain the best timing of injectioning the polymer turning to injection water.According to the previous experience we also sum up the methods of injectioning the polymer to injection water.
