国内外页岩气钻井液技术应用现状

介绍了国内外页岩气钻井液技术及其应用情况，大部分页岩油气水平井采用油基钻井液，直井或定向井多采用水基钻井液；国内油基钻井液技术较为成熟，处理后的含油钻屑能达到环保要求。

Application Actuality of Shale Gas Drilling Fluid Technology at Home and Abroad

With the further exploration of oil and gas, shale gas development had gradually attracted the global attention. American was the earliest country of developing shale gas and had the most advanced technology. China had completed a certain number of shale gas wells since 2011 . The article mostly introduced shale gas drilling fluid technology at home and abroad and its application. Oil-based drilling fluid was mainly used for shale gas horizontal wells, and water-based drilling fluid was mainly used for vertical or directional wells. Oil-based drilling fluid tech-nology at home increasingly well formed and could meet the drilling requirements of the field, and deoiled drilling cuttings could meet the requirements of environmental protection.
