聚合物调剖剂在吉林新立裂缝性油藏中的应用

Reaserch on Section Adjustment Using Polymer in Jilin Xinli Fracturing Oil Filed by NMRI

摘要: 目的:本文利用核磁共振技术系统地研究了聚合物调剖剂在吉林新立裂缝性油田中的应用。方法:利用多层平面物理模拟技术测试了不同聚合物对调整吉林新立油田中的作用和机理,实验集中测试了各阶段的油水饱和度及分布状况;结果:最后,研究不同的调剖剂注入量下剩余油的分布规律,提出调剖措施实施意见。结论:为裂缝性砂岩低渗透油田的合理、高效开发提供有力的支持。

Abstract: Objective : Study the polymer section adjustment using in Jilin Xinli fracturing oil filed. Methods : NMRI and mutilayers models were used in the paper. Result : NMRI and mutilayers model is suitable for the research on polymer section adjustment. Conclusions : The developing degree of low and middle permeability layers were improved after the adjustment in high permeability area.
