摘要：
A method of servicing a wellbore comprising preparing a composition comprising a calcium aluminate cement, water, and a fluid loss additive wherein the fluid loss additive comprises an acid gelling polymer, placing the composition in the wellbore, and allowing the composition to set. A method of servicing a wellbore comprising placing into a wellbore having a bottom hole static temperature of greater than about 50° F. and/or a pH of from about 3 to about 9 a cement slurry comprising a calcium aluminate cement having an aluminum oxide content of greater than about 60 wt. % based on the total weight of the calcium aluminate cement and an acid-gelling polymer wherein the cement slurry has a fluid loss at 10 cc/10 min. to about 600 cc/30 min.
