茨4块为普通稠油油藏,进行注水开发阶段后平面矛盾突出,研究并应用表面活性剂驱油技术,在调剖实施后的有效期内,通过驱油技术尽可能的提高采收率,取得了显著的措施效果。
The four blocks are common heavy oil reservoirs. After the water flooding development phase, the plane contradictions are prominent. By the research and application of the surfactant flooding technology, the recovery efficiency can be enhanced as much as possible through the flooding technology after the profile control is implemented. Achieved remarkable results.
