摘　　要：为进一步提高河南双河油田聚合物驱后原油采收率,进行了聚合物驱后利用OCS表面活性剂／聚合物二元体系驱油性能的研究。结果表明,OCS表面活性剂／聚合物二元体系是一种高效驱油剂,聚合物驱后利用OCS表面活性剂／聚合物二元体系可以进一步提高原油采收率。利用交联聚合物与OCS表面活性剂／聚合物二元体系相结合进行驱油的实验结果表明,聚合物驱后先用交联聚合物进行调剖,再注入OCS表面活性剂／聚合物二元高效驱油剂,提高采收率的效果更好。Displacement performance of OCS surfactant/polymer binary system was investigated for enhancing oil recovery in Shuanghe Oilfield after polymer flooding. The experimental results showed that OCS surfactant/polymer binary system was a high efficiency oil displacement agent and it could improve oil recovery further after polymer flooding. The oil displacement experiment of OCS surfactant/polymer binary system combination with cross - linked polymer afetr polymer flooding showed that higher oil recovery would be achieved if cross - linked polymer was used for profile control and then OCS surfactant/polymer binary system was injected.
