环保型钻井液可以保护储层，防止生态环境被破坏。本文主要介绍了国内外环保型钻井液的研究现状及进展，其中包括甲基葡萄糖苷钻井液体系、聚胺类钻井液体系、合成基钻井液体系、有机盐钻井液体系等，对这些钻井液体系做了评价和比较，并对环保型钻井液今后的发展方向提出了建议。参45

The environmentally friendly drilling fluid can protect the reservoir stratum，and prevent environment from being destructed. In the paper，the current status and progress of the environmentally friendly drilling fluid at home and abroad，including methyl glucoside drilling fluid system，polyamines drilling fluid system，synthetic-based drilling fluid system，organic salt drilling fluid system，were mainly introduced. The drilling fluid system were evaluated and compared，and some suggestions were provided for the relevant developments，which were expected in the future.
