摘　　要：海洋钻井要求钻井液满足常规性能的同时,还要求钻井液毒性小、生物降解性好、无生物积累以及排放后对环境无害等。因此,海洋钻井液技术的一项重要内容是其环境可接受性评价技术。文章在对钻井液体系及其处理剂在海水中的环境可接受性评价方法进行概括基础上,重点介绍了近年来海洋钻井液体系的研究及应用状况,指出了海洋钻井液技术存在的问题和发展趋势。Offshore drilling fluid should have environmentally friendly properties as well as good conventional properties. So environmentally friendly property evaluation is one of the main aspects in the study on offshore drilling fluid technology. The methods for evaluating the toxicity and biodegradation of drilling fluid and its additives in seawater are reviewed. The state of the study on offshore drilling fluids and their applications in recent years is discussed. The problems existing in the development of the offshore drilling fluids are pointed out, and the development direction in the study and application of the offshore drilling fluids is put forward.
