适用于页岩气井的水基钻井液技术研究

Water-based Drilling Fluid Technology for Shale Gas Wells

通过分析页岩水基钻井液存在的施工难点问题,开展了页岩气水基钻井液体系研究,优选了抑制剂、润滑剂以及降滤失剂,得到了适用于页岩气井的水基钻井液体系配方。

By analyzing the construction difficulties of shale water-based drilling fluid,the shale gas-water-based drilling fluid system was studied. The inhibitors,lubricants and filtrate loss reducers are optimized,and the formulation of water-based drilling fluid system suitable for shale gas wells was obtained.
