A kind of cement slurry, which is used under deep water and low temperature is studied in the paper, in order to overcom eproblems, such as low temperature, slow strength, shallow flow and leakage. The low temperature rapid strength cement, light material and a serial of additives were considered. The cement slurry can meet the general requirements for cementing casing in deep water wells. The exceptional features are, temperature from 4 ℃ to 20 ℃, density range from1.2g/cm~3 to 1.7g/cm~3, rapid strengths development, no sedimentation, etc.
