针对八面河油田面37块水淹程度高,采出程度低,注汽压力高,开发效果变差的实际,通过分析研究认为边水水侵为影响开发效果的主要因素。针对水侵影响因素,研制出了配套的技术对策。通过方案优化认为:通过减小吞吐周期、内外部提液以及注高温泡沫剂调剖堵水都可以有效抑制边水侵入,改善稠油热采开发效果。 In view of the fact that there are 37 flooded areas in Bamianhe oilfield, the degree of flooding is low, the degree of recovery is low, the pressure of steam injection is high, and the development effect is deteriorated. According to the analysis and research, the waterfront invasion is the main factor affecting the exploitation effect. Aiming at the influencing factors of water intrusion, a series of technical measures have been developed. Through the optimization of the program, it can be concluded that: by reducing the throughput cycle, internal and external liquid extract and injection of high temperature foam profile control plugging water can effectively inhibit edge water intrusion, improve the development of heavy oil thermal recovery effect.
