根据任丘油田灰岩油藏稳产仍以控水稳油为主，而采用常规有机堵剂堵水，特别是对高渗透层堵水效果逐渐变差，因此需要一种耐高温高强度的堵水剂封堵大孔道。TC－938堵剂适应上述要求满足了堵水工艺要求，该堵剂即具有吸附作用堵水，又具有物理堵塞作用堵水，担负了堵剂在地层中的滞留性能，粘附性好。实施的11井次有效率90．9％，措施增油6100t，为实现稳产提供了保证。
According to the stable production of limestone reservoirs in Renqiu Oilfield, oil control and oil stabilization is still the main issue. However, the use of conventional organic plugging agents to block water, especially the effect of plugging water in high permeable permeation layers, is getting worse. Therefore, a high temperature and high strength plugging Aqueous plugging large channels. TC-938 plugging agent to meet the above requirements to meet the water plugging process requirements, the plugging agent that has the role of adsorption water, but also has the role of physical plugging water, responsible for the blocking agent retention in the formation of performance, good adhesion. The implementation of 11 wells 90.9% efficiency, oil measures 6100t, to provide a guarantee for stable production.
