| 摘 要： | 本文通过实验研发出了调剖用星形聚合物CQS-1及延迟交联剂CJL-3,制备出一种聚合物凝胶。该凝胶具有延迟交联性能,其成胶时间为46.5h,成胶后粘度65893mPa·s,成胶后的凝胶置于60℃温度时老化6个月,粘度保留率为88.5%,凝胶代码为D型。研发的延迟交联聚合物凝胶性能满足长庆油田注水井用弱凝胶调剖剂技术要求,可用于油田注水井调剖。

| Abstract: | Profile agent of polymer CQS--1 with star--shape and retarding crosslinking agent CJL-3 were explored. A polymer ger was explored through experiments. This gel has delayed crosslinking prop- erty. It has crosslinking time of 46.5h and viscosity of 81457mPa·s after completely crosslinking. Placed in 60 ℃ after 6 months, its viscosity retention rate is 88. 5%, the gel code is D. All its properties satisfy the technology requirements of Changqing oilfield injection well weak gel profile control agent. This gel can be applied in Changqing Oilfield water injection well for profile measures. |
