化学聚合物深部调驱技术及应用

Chemical polymer deep profile control and flooding technology and its application

近年来,化学聚合物深部调驱采油技术被不断的应用于油田现场,能有效降低油井含水,实现良好的增油效果。通过裂缝体系调控过程动力学机理分析,提出只有利用多段塞流在深部提高油水井间的压力梯度能有效提高采收率,研发了深部整体调剖凝胶体系,应用于油田实践效果较好。

In recent years,chemical polymer deep profile control and flooding technology has been continuously applied in oil field,which can effectively reduce water cut of oil wells and achieve good oil increase effect.Through the analysis of the dynamic mechanism of the regulation process of the fracture system,it is proposed that only using the multi slug flow to raise the pressure gradient between the oil-water wells in the deep part can effectively enhance the recovery factor.The deep whole profile control gel system has been developed and applied to the oilfield with good practice results.
