摘要

摘要: 近年来，北极地区石油勘探开发进度明显加快，市场前景良好。针对北极永久冻土层最低温度达-9℃的超低温以及该地区作业时间宝贵的问题，要求水泥浆体系在负温环境下候凝时间短且24 h有强度发展。通过研发低温胶凝材料C-SE8和缓凝剂H10S，并复配G级油井水泥和其他添加剂，分别用淡水、海水和14% NaCl溶液配制超低温水泥浆体系。评价结果表明，密度为1.50 g/cm³的水泥浆在-10℃下的24 h抗压强度可达3.6 MPa以上，密度为1.90 g/cm³的水泥浆在-10℃下的24 h抗压强度可达6.8 MPa以上；该体系适用温度为-10℃～30℃，浆体具有良好的流变性能，且稠化时间易调整，满足北极永久冻土层固井施工要求。

Abstract: Petroleum exploration and development in the Arctic area in recent years has been accelerating. Well cementing operation in this area has long been facing with ultra-low temperature (-9 ℃) and the precious time available for operation; the cement slurry is required to have strength development in 24 hours at temperatures below zero. Using a self-developed low temperature gelling agent C-SE8 and a self-developed retarder H10S, several ultra-low temperature cement slurries were formulated with class G cement and other additives in fresh water, sea water and 14% NaCl solution. Evaluation of the cement slurries showed that a cement slurry of 1.50 g/cm³ had 24 h compressive strength of at least 3.6 MPa at -10 ℃; another cement slurry of 1.90 g/cm³ had 24 h compressive strength of at least 6.8 MPa at -10 ℃. The working temperatures of the cement slurries were between -10 ℃ and 30 ℃. The cement slurries had good rheology, and the thickening time can be easily adjusted, making them suitable for well cementing in arctic permafrost.
