摘要
采用泡沫综合指数评价方法结合三元复合体系界面张力特征 ,系统地研究了适合大庆油田地层条件的泡沫复合体系配方。同时 ,对泡沫复合体系国产化配方也进行了探索性研究 ,并获得良好的效果。室内驱油实验结果表明 ,泡沫复合体系的驱油效率比水驱提高 30 % (OOIP)以上。
This paper studies a foam complex system formulae which is suitable for the formation condition of Daqing Oil Field using foam comprehensive exponent evaluation method and combining with the characteristic of the interfacial tension of ASP system. It also studies the localized formula of foam complex system and obtains a nice effect. Laboratory displacement experiment result shows that the displacement efficiency of foam complex system is 30% (OOIP) higher than water displacement. This provides a theoretical and practical basis for the popularization of foam complex flooding.
