摘要
针对单家寺稠油油田蒸汽吞吐后期蒸汽利用率低的状况,研制出多效复合驱油体系,它具有调剖、洗油、降黏三效合一的功能。泡沫剂作为表面活性剂,本身具有一定的降低油/水界面张力的作用,通过探讨与不同种类和性能的表面活性剂之间的复配协同作用,优化表面活性剂发泡性与界面活性,实现蒸汽的流度控制,提高蒸汽吞吐的采收率。
In view of low utilization ratio of later stage steam during steam simulation in Shanjiasi heavy oilfield,developed multi-efficiency combination flooding system,it has capacities of profile control,washing oil and decrease viscosity.As one of surface acting agent,Frother can decrease interfacial tension of oil and water,researched synergetic effect of different surface acting agent,optimized foaminess and interfacial of surface acting agent, realized mobility control of steam,advanced recovery ratio of steam simulation production pattern.
