| 摘 要： | 氮气泡沫热力驱是一种新的提高稠油油田采收率的方法。利用油田现场提供的起泡剂和原油等资料，从室内实验和现场应用两个方面，研究了氮气泡沫调剖在稠油热采中提高采收率的机理，并通过实验对泡沫剂进行优选和评价。驱替实验表明，最终驱油效率可达81．44％，比水驱提高了34．3％，残余油饱和度达到11．14％。同时，进行了氮气泡沫调剖的矿场设计和应用效果分析，现场应用表明，氮气泡沫调剖能较大幅度降低油田含水，提高采收率。

| Abstract: | Nitrogen foam thermal flooding is a new method for enhanced oil recovery of heavy oil. On the basis of the data of foaming agents and crude oil which are supplied in field, the mechanism of nitrogen foam profile control used for enhanced oil recovery in heavy oil thermal production is studied, and optimization and evaluation of foaming agents are carried out by laboratory test. The results of displacement experiment indicated that ultimate oil displacement efficiency is high up 81.44%, and is increased by 34.3% than water flooding, the residual oil saturation is 11.14%. At same time, the field design and application effect of nitrogen foam profile control are analysed. The field application shows that nitrogen foam can reduce greatly water-cut, and enhance recovery efficiency. |
