摘　　要：针对温度、水灰比、缓凝剂这些影响水泥候凝时间的主要因素展开了试验研究。试验结果分析得出 :1对同一温度同一缓凝剂 ,水灰比每减少约 1 0 % ,最佳时间相应减少 1～ 3h;2对同一水灰比同一缓凝剂 ,温度每升高 1 0℃ ,最佳测井时间缩短约 2 h;3对同一温度同一水灰比 ,缓凝剂增加 0 .2 % ,最佳测量时间延迟 2～ 3h;4温度、水灰比、缓凝剂都是单独起作用 。The key factors such as curing temperature,water cement ratio and cement retarder,which influence the cement curing time, are studied experimentally The experimental results demonstrate that: ①optimal logging time reduces 1~3 hours when the density of cement slurry increases 0 1g/cm 3 under the conditions of the same temperature and same cement retarder;②optimal logging time reduces about 2 hours when the temperature increases 10℃ under the conditions of the same water cement ratio and same cement retarder;③optimal logging time delay 2~3 hours when cement retarder increases 0 2% under the same temperature and same water cement ratio;④temperature, water cement ratio and cement retarder act independently
