摘要
为使水敏性稠油油藏注汽热采能顺利进行,合成了新型高温粘土稳定剂XFP-2,并对其耐温、抗盐、耐水洗和粘土防膨性能进行了评价。实验结果表明,XFP-2防膨能力强,室温、高温时的防膨率均超过90%,具有长效、抗盐的特性,XFP-2耐温可达300℃以上,能满足注蒸汽条件下开采稠油的需要。现场应用表明,该粘土稳定剂能有效保护油层,提高稠油油藏注汽开发效果。
A new durable clay stabilizer XFP - 2 for high temperature use was synthesized for exploiting water sensitive heavy oil reservoir by steam injection effectively. Its properties, such as salt resistance, acid or alkali resistance ,temperature tolerance, and inhibition of clay - swelling, were investigated. The results showed that anti - swelling ability of XFP - 2 was strong and ,its anti - swelling ratio for Na - montmorillonit was all over 90% at room temperature or 300℃ . It was long life for anti - swelling of clay and had the resistance to brines, acids and alkalis. XFP - 2 might meet the need of heavy oil thermal recovery. The field application of XFP - 2 showed that it could protect formation effectively and improve the effect of heavy oil steam thermal recovery.
