| 摘 要： | 深层特稠油油藏冷42断块依靠蒸汽吞吐开发,由于回采水率较低,因此开发效果较差.利用GO2易溶于原油中、能够降低原油粘度、体积膨胀等特性,进行GO2吞吐研究.通过现场试验,改善了开发效果,提高了原油采收率,为同类型油藏开发提供了一定的借鉴.

| Abstract: | The deep, extra - heavy oil reservoir in Leng 42 fault block is recovered by cyclic steam stimulation. The rate of water back production is low and the development is unsatisfactory. CO2 is easy to dissolve in oil, can reduce oil viscosity, and has volumetric expansion feature, so that study of CO2 flooding is conducted. Field test has shown improved development effect and recovery factor, and provided reference to similar reservoirs. |
