聚合物微球调驱技术的实际应用及效果评价

Practical application and effect evaluation of polymer microsphere profile control and flooding technology

聚合物微球技术是近年来发展起来的一种新型深部调驱技术,本文通过现场实际应用的数据分析,总结了粒径、用量、排量、浓度各项参数与实施效果的关系,确定不同渗流类型油藏合理的体系及注入参数,以提高措施有效率和有效期。

Polymer microsphere technology is a new deep profile control and flooding technology developed in recent years. Based on the data analysis of field application, this paper summarizes the relationship between the parameters of particle size,dosage,displacement and concentration and the implementation effect,and determines the reasonable system and injection parameters of reservoirs with different percolation types in order to improve the efficiency and validity of the measures.
