The Preparation of Alkaline Chromium Sol In-Situ Crosslinking Agent
摘要
Abstract
The sol type organic chromium crosslinking agent was synthesized by the method of changing the dispersion medium ,which used the chromium chloride and acetic acid as the main raw materials .The crosslinking performance evaluation with HPAM the profile control system was made .The results show that the high strength and stability gel can be made when n(Cr3+ )/n(Ac- ) is (1∶ 2 .5)~ (1∶ 3 .0) ,mass concentration of Cr3+ is 197 ~ 328 mg/L ,and pH is 7 ~ 9 .The novel chromium crosslinking agent presented a good stability in the alkaline solution .Futhermore ,it is suitable for deep reservoir in-situ crosslinking ,which can enhancement of oil recovery .关键词
