摘　　要：针对高温高盐裂缝型油藏常规堵剂存在耐温耐盐性差、封堵强度弱、有效期短等问题,以海上J油田为目标,通过室内研究成功由高分子共聚物(由2-丙烯酰胺-2-甲基丙磺酸(AMPS)和丙烯酰胺(AM)共聚而成,简写为AM-AMPS,下同)和复合交联剂FHJLJ-3组成的耐温耐盐高强度化学堵剂配方。室内性能评价实验表明,该堵剂成交时间48h,成胶强度152133mPa·s,物模封堵率为97.82%,且具有良好的耐冲刷性能。将该堵剂在海上J油田进行了现场应用,取得了较好的增油降水效果。Aiming at the high temperature and high salt fractured reservoir,conventional plugging agent has the problem of poor temperature and salt tolerance,weak plugging strength or short term of validity.With the aim of J offshore oilfield,through the lab study,high-strength chemical water blocking agent was composed of AM-AMPS of salt-resistant,temperature-resistant polymer and FHJLJ-3 of compound cross-linking agent.The experimental results showed that the cross-linking time is 48 hours,the gel viscosity is 152133 mPa·s,the plugging rate is 97.82%,and it has good washing resistance.The plugging agent has been applied in the J offshore oilfield,and it has a good effect of increasing oil and reducing water.
