摘　　要：根据微细水泥的特点,开发出了适合微细水泥-漂珠低密度水泥体系的复合早强剂和密度1.20～1.50g/cm3的低密度水泥体系,在50℃条件下测试了密度1.20～1.35g/cm3四个密度水泥浆的各项性能。实验表明,该水泥体系具有早期强度高,稳定性良好,稠化时间可调,并具有一定的防漏和防气窜功能。According to the characteristics of micro-fine cement, a compound early strength agent and light weight cement with 1.20 g/cm3 to 1.50 g/cm3 were developed which are suited to the micro-fine cement - drift bead light weight cement slurry. Several performances of the light weight cement slurries were tested whose density is between 1.20 g/cm3 to 1.35 g/ cm3 at 50℃. The results indicated that the cement slurries have high early strength, good stability, adjustable thickening time, and the functions of protecting leak and trip gas
