摘要:

根据中原油田高温、高矿化度等复杂地质条件油藏特点,为提高油藏开发效果,研制适合该油藏特点的调剖剂,有效的解决油藏层间矛盾,提出了由HPAM与复合交联剂等在一定条件下反应制成了颗粒状高分子调剖剂CSL-2,并对其进行了性能评价实验。调剖剂耐温130℃,耐盐2.0×105mg/L(Ca2+、Mg2+:5 000 mg/L),其吸水后膨胀倍数达50倍以上,膨胀体强度较满意。高分子调剖剂加入破胶剂后,可以降解为溶液,克服了同类调剖剂的缺点,使用安全。其综合性能优于国内部分同种类型产品,可用于油层深部调剖。

关键词: 耐温, 抗盐, 颗粒状树脂调剖剂, 膨胀倍数

Abstract: In order to improve the development effect of reservoirs solve the conflicts between layers, a grain polymer profile con-trol agent CSL-2 that HPAM reacts with compound crosslinker has been developed in the light of the reservoir features with high salinity and temperature in Zhongyuan oil field, and its
performance has been evaluated. Results show that CSL-2 can work in temperature up to 130℃, salinity as much as 2.0×105ml/L (Ca2+,Mg2+: 5 000 mg/L), swelling times nearly 50 after absorbing water with satisfied swelling strength. When adding gel breaker, it can be degrade to solution, which over-
comes the shortcomings existing in the same type profile control agent. The comprehensive performance is better than the same type products in China, and can be used in the reservoirs with depth.

Key words: temperature resistance, salt resistance, grain resin profile control agent, swelling times
