通过配伍性、地层温度下的发泡性能、耐高温性能、高温发泡性能和阻力因子等室内试验 ,筛选出性能较好的发泡剂。并在孤岛油田配合注蒸汽实施了氮气泡沫堵水调剖措施 ,降低了油井的综合含水 ,增油效果明显 ,提高了稠油采收率。 Through the compatibility test, foaming property at formation temperature, high temperature resistance, high temperature foaming property and resistance factor, the best performance foaming agent was screened out. In Gudao Oilfield, steam injection with nitrogen foam has been implemented to control water and water profile, reducing the comprehensive water cut of the oil well, increasing the oil yield and increasing the recovery rate of heavy oil.
