本文对高效复合剂LH1的合成、添加高效复合剂改善稠油蒸汽吞吐效果的机理进行了研究,并在辽河油田的部分区块进行了现场应用。该工艺不仅能改善蒸汽的波及体积,提高采收率,而且还能明显提高采油速度,不同程度降低含水率和节能降耗,获得了明显的经济效益。并在曙光油田稠油区块进行了现场应用,取得了良好的增油效果。
In this paper, the synthesis mechanism of high efficient compound LH1 and the mechanism of adding high efficient compounding agent to improve the effect of heavy oil steam huff and puff were studied and applied in some blocks of Liaohe Oilfield. The process can not only improve the steam volume and improve oil recovery, but also significantly improve oil recovery rate, reduce water content and energy consumption in varying degrees, and obtain obvious economic benefits. In the Shuguang heavy oil block, the field application was made and a good oil increasing effect was achieved.
