It is of great significance to study gas hydrate because of following reasons. (1) Most organic carbon in the earth reserves in the form of natural gas hydrate, which is considered as a potential energy resource for the survival of human being in the future. (2) A series of novel technologies are based on gas hydrate. (3) Gas hydrate may lead to many hazards including plugging of oil/gas pipelines, accelerating global warming up, etc. In this paper, the latest progresses in exploration and exploitation of natural gas hydrate, the development of hydrate-based technologies including gas separation, gas storage, CO2 sequestration via forming hydrate, as well as the prevention of hydrate hazards are reviewed. Additionally, the progresses in the fundamental study of gas hydrate, including the thermodynamics and kinetics are also reviewed. A prospect to the future of gas hydrate research and application is given. 相似文献

含防聚剂水合物浆液在循环管路中的性能 总被引:1,自引:0,他引:1
采用高压循环管路对含防聚剂的油-水-气体系形成的水合物浆液的稳定性进行了评价。实验结果表明,随循环时间的延长,含Zjj2防聚剂的水合物浆液的流量逐渐下降至趋于稳定,表观黏度不断增大至趋于基本不变,未出现堵塞管路的现象;生成的水合物以小颗粒形态均匀分散在乳液中,水合物浆液停工前、后的形貌相同,稳定性较好;油-水-气体系中水含量越高,含Zjj2防聚剂的水合物浆液的流量下降程度越显著,表观黏度越大;与分别含Span20和Zjj1防聚剂的水合物浆液相比,含Zjj2防聚剂的水合物浆液的表观黏度最低、流动性最好。 相似文献
