摘要： 针对长庆油田中高温(≥70℃)油井水淹问题,以耐温耐盐的多元共聚物为主剂,配以交联剂和稳定剂,制得了耐温耐盐凝胶型堵水剂DQ-4。优选出了堵水剂DQ-4的最佳配方(质量分数):0.6%主剂+0.2%交联剂 +0.1%稳定剂。采用瓶试法成胶实验、流变实验和岩心流动实验评价了DQ-4的各项性能。实验结果表明,DQ-4 的各项性能指标均达到了现场应用的要求。2010-2011年在长庆油田现场试验11口井,措施有效率72.7%,累计增油2023.38t,初步实现了对水淹油井的降水增产,取得了较好的经济效益。

Abstract: With multipolymer, crosslinking agent and stabilizing agent as the raw material, a selective geltype plugging agent with heat resistance and salt tolerance was prepared in laboratory in order to solve the flooding problems of medium to high temperature(≥70 ℃) oil wells in Changqing oilfield. The optimum composition was determined as follows: multipolymer 0.6%, crosslinking agent 0.2%, and stabilizing agent 0.1%. Gelling experiment, pheological experiment and core flow experiment were carried out to characterize the performances of DQ4 system. The results show that the performances of DQ4 system have met the field application requirements. 11 wells in Changqing oilfield were plugged with the plugging agent in 20102011, the effective rate is 72.7%, and the total increased oil is 2 023.38 t. The economical benefit was satisfied.
