聚堵动态特征、机理及定量评价方法研究
|
摘要
随着越来越多油田采用聚合物驱提高采收率,聚合物堵塞现象越来越受到现场工程技术人员及科研人员的重视。但目前对于聚合物堵塞的研究成果主要集中在聚合物堵塞机理及解堵措施研究上,对聚合物堵塞井动态特征、堵塞机理及其定量评价方法的系统研究欠缺。通过总结聚合物堵塞井动态特征,进一步分析了堵塞物的成分与堵塞机理,在此基础上,针对堵塞对产能的影响进行分析并提出了定量评价方法,为今后采取有效的解堵措施与生产评价提供了理论依据。
Polymer flooding was used in more and more oilfields to improve oil recovery and polymer clogging is increasingly valued by field workers and scholars. However,the current research results are mainly focused on the mechanism of polymer plugging and the corresponding plugging measures,but there is still a lack of systematic study on the dynamic characteristics of polymer plugging wells,plugging mechanism and the impact on productivity. The dynamic characteristics of polymer plugged wells are systematically summarized,and the components of clogging are analyzed. The plugging mechanism is analyzed in detail.On this basis,the influence of productivity is analyzed and studied. It was meaningful for providing a theoretical basis on taking measures.
