摘要
介绍了由地面交联膨体颗粒型、地层内引发聚合型及絮凝聚合物组成的复合型调剖剂 ,深部调剖封堵大孔道技术。该项技术利用各调剖剂之间的协同效应 ,对堵剂进行合理组合 ,采取段塞式注入工艺 ,实现有效封堵地层深部大孔道的目的。
The paper presents a compounded profile control agent which is composed of surface crosslinked expansion grain and flocculation polymer etc.,Deep-seated plugging and profile control technologies in macropore are also introduced.The technologies can effectively realize the goal of plugging macropore by utilizing the cooperation effect among profile agents and reasonable combination of plugging agents.
