油田注入水配制聚合物凝胶调剖体系的稳定性及适应性

Research on Stability and Adaptability of a Polymer Gel Profile Control System Prepared with Oilfield Injection Water

在吉林新立油田新北区块注入水水质分析结果的基础上,进行了聚合物凝胶调剖体系与油田该区块注入水的适应性研究,优选出与吉林新立油田注入水配伍的聚合物、交联剂、杀菌剂类型及其配方。结果表明,优选的调剖体系配方在90 d内表现出较高的强度及良好的稳定性。

Study on the compatibility of polymer gel profile control system with the injection water used in Xinbei Block of Xinli Oilfield, Jilin Province, was carried out, and the kinds and compositions of polymer, erosslinker and bactericide compatible with the injection water were identified based on the analyses on the in- jection water. The results have shown that the optimized profile control system is of high strength and good stability within 90 days.
