鲁页参1井钻遇地层复杂，水敏地层造浆严重，二叠系地层坍塌掉块，出现卡钻事故，导致钻井施工进度慢，风险大。针对钻井施工中存在的技术难题，开展了一系列的技术攻关，确定了一开和二开以及取心段的钻井液体系，形成了一整套钻井液技术和工程技术措施。实践表明，该套钻井液体系解决了鲁页参1井钻井中出现的坍塌、掉块等难题，减少了井下故障的发生，提高了钻进速度，建井周期明显缩短，为以后的钻井施工提供了技术支持。

The drilling of shale gas parameter well-1 of Shandong encountered complex formations with serious mud mak-ing in water sensitive formation and collapsed block in Permian strata.The jammed bit accident led to slow drilling con-struction progress with high risk.According to the technical difficulties in the drilling process, the drilling fluid system for the first and the second as well as the coring sections are determined by a series of technology research to form a complete set of drilling fluid technology and engineering measures.The results show that the difficulties such as collapsed block are solved by this drilling fluid system in the shale gas parameter well-1 of Shandong, the downhole accidents are reduced with improved drilling speed and short well construction period.
