摘要: A well completion spacer fluid is provided which particularly suitable for separating a cement slurry from drilling in primary cementing operations. The also useful other potentially incompatible fluids the wellbore, such as, brine. basically comprises water, hydrous magnesium silicate clay, silica and organic polymer(s).
