萨北油田北二区泡沫复合驱矿场试验

Field experiment of ASPfoam combination flooding in Bei 2 area of Sabei oilfield.

阐述了世界首次泡沫复合驱先导性矿场试验 ,介绍了该试验取得的效果及其与三元复合驱动态特点的区别。分析认为 ,泡沫复合驱剂在油层中形成了泡沫 ,该泡沫复合驱可比水驱的采收率高 30 %左右。

The first pilot field experiment of ASP (alkalinesurfactantpolymer)foam combination flooding in the world is discussed in this paper. The experimental effect and its performance difference from ASP combination flooding are introduced . It is considered that foam was produced in oil layers in the process of the field experiment due to foam combination flooding agency. Recovery efficiency in ASPfoam combination flooding is about 30% more than that of conventional water flooding.
