摘要
在筛选发泡性能好、稳定性强的AK系列活性剂和稳泡能力强的TY - 10的基础上 ,采用复配增效原理 ,研制成DP - 4型泡沫剂。驱油试验时 ,对其发泡能力、稳定性与地层水的配伍性及耐油性进行了评价。结果表明 ,DP- 4型泡沫剂的泡沫性能良好 ,可提高采收率 18%。
Based on the selection of AK series surfactant with good foaminess and strong foam stability and TY-10 with good foam stability, DP-4 foaming agent is developed applying the principle of compounding for higher efficiency. Its foaming capacity, stability, compatibility with formation water and oil resistance are evaluated in oil displacement test. The result shows that foaming performance of DP-4 type of foam agent is good, and EOR will increase 18%.
