Abstract
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
