| 摘 要： | 针对濮53块油藏开发中出现的含水高、递减快和常规工艺措施难以解决注入水沿高渗条带突进等问题，提出了利用表面活性剂与聚合物微球复合进行深度调剖，并利用界面张力法和真实砂岩模型对该体系的注入方式和表面活性剂/聚合物微球的驱油效率进行了研究。研究表明，分开注入聚合物微球和表面活性剂可使非均质性得到改善，驱油效率也得到大幅提高。这种复合调剖体系具有良好的调剖效果，既提高了波及系数又能提高洗油效率。

| Abstract: | Aimed to poor profile-control effect due to severe heterogeneity and high water cut stage in PU-53 block,we put forward using surfactant-polymer microsphere system to depth profile modification.And we study the injection pattern and displacement efficiency by mea- suring the interracial tension and using sandstone micro model displacement experiment. Studies have shown that separate injection of polymer microsphere and surfactant can modify horizon aeolotropic and improve oil-driving efficiency.Surfactant-polymer microsphere sys- tem has good effect of profile control,can not only improve the sweep efficiency and can im- prove the efficiency of washing oil. |
