聚合物活性微球调驱是一种全新的可移动式调剖驱油剂。适用于高含水油田、断块油田,可大幅提高油田采收率。聚合物活性微球能在油层岩石孔隙中运移,多个微球的堆积能封堵大孔道使水绕流,同时封堵压差升高到一定程度,微球发生弹性变形,通过喉道继续向油层深部运移。本文是对聚合物活性微球调驱在文10东块可行性研究过程的阐述。
Polymer activated microsphere tuning is a new type of mobile profile control oil displacement agent. For high water-cut oilfield, fault block oilfield, can greatly improve oil recovery. The polymer microspheres can migrate in the rock pores of the reservoir. The accumulation of multiple microspheres can block the large pores and make the water flow around. At the same time, the pressure differential increases to a certain extent and the microspheres are elastically deformed. Continue to deep migration to the reservoir. This article is an illustration of the feasibility study of polymer microspheres in the East Block.
