胜利油田相继在罗家等区块部署了页岩油藏水平井，用于页岩油的开发。页岩地层层理和微裂缝发育，钻井过程中极易引起井壁失稳问题。同时，由于水平段较长，也存在着润滑、井眼清洁等难题。针对施工难点和风险，研究制定了页岩油藏钻井液方案，二开采用胺基钻井液体系，三开采用油基钻井液，顺利地完成了钻井施工。就胜利油田页岩油藏钻井液技术进行了介绍和分析，针对应用过程中存在的一些问题进行了探讨，对页岩油藏的勘探开发有一定的启示作用。

Shale oil horizontal wells were arranged in Shengli oilfield, including Luojia and some other blocks for shale oil development.With shale bedding and micro fissure developing, the borehole instability is extremely easy to be caused in drilling process.At the same time, due to the long horizontal section, there are the difficulties of lubrication and borehole cleaning.For the construction difficulties and risks, the drilling fluid scheme for shale oil reservoir was worked out by re-search:amine-based and oil-based drilling fluid system being used for the second and the third sections respectively, and the drilling construction was successfully completed.The drilling fluid technology used for shale oil reservoir in Shengli oil-field is introduced in this paper and the discussion is made on some technical problems in the application.
