摘　　要：通过分析大庆油田聚合物注入井存在的问题及压裂工艺的不适应性 ,研究出了适合于聚合物注入井特点的新型综合压裂解堵技术 ,通过现场应用 ,提高了措施效果 ,延长了有效期 ,减缓注聚井的层间矛盾 ,取得了较好的效果 ,并取得了一定的经济效益 。Base on analysis of the problems of polymer injection wells and the inelasticity of fracture in Daqing Oilfield , a new fracture and plug removal technology was put forward. After field application, a better effect was gained, such as the period of validity being prolong, the contradiction between layer being relax. A economic benefit was obtained. This may have a guidance function to plug removal in polymer injection wells.
