大洋科学钻探与天然气水合物的勘探开发都离不开钻井，且两者都会面临水合物形成和分解造成的风险。而钻井液是钻井工程的“血液”，因此，学术界和工业界对钻井液体系进行了深入研究，提出和设计了不同类型钻井液配方以服务于科学钻探和水合物安全高效钻采。该文综述了大洋科学钻探与水合物钻井特点及风险和相应钻井液性能需求，总结了国内外常用钻井液体系及性能评价，指出了当前研究存在的问题，并提出了今后钻井液体系发展方向，从而促进我国水合物商业化开采进程和服务于大洋科学钻探。

Both ocean scientific drilling and exploration and development of gas hydrates are closely associated with well drilling, and both of them have the risks caused by hydrate formation and dissociation. Drilling fluid is treated as the "blood" of drilling engineering. Therefore, the drilling fluid system has been deeply studied by academia and industry, and different types of drilling fluids have been proposed in order to serve the scientific ocean drilling and the safe and efficient production of hydrates. This paper summarized the characteristics, risks of scientific ocean drilling and hydrate drilling and performance requirements of the drilling fluids as well as drilling fluids commonly used at home and abroad and their performance. This paper pointed out the existing problems in current research, and suggested further possible research directions of drilling fluids, so as to promote the commercial development of hydrate and serve ocean scientific drilling.
