摘要
用钠膨润土、防窜降滤失剂配制成了膨润土水泥浆，用于百色油田３口油气井的固井施工，效果良好，提高了油层、水层及油水同层的封固质量。本文介绍了配方研究、性能测试结果及现场应用概况。
The tittled cement slurries are prepared by introducing Na bentonite, an antichannelling/filtrate reducing agent , J 2B, and, in some cases, CaCl 2 and successfully used for cementing 3 oil/gas wells at Biase Oil Fields of Guangxi. The composition of the slurries is presented. These slurries are slightly expanding at setting, early strengthening and strongly thixotropic, have good rheologic behavior and low filtrate losses.
