摘要
昌页参1井终孔深度3204.72 m,揭露地层较为复杂,取心段较长。本文从井身结构、钻具组合、钻探设备、钻头和钻进参数、钻井液等方面对钻井施工情况进行了阐述。重点介绍了保证高岩心采取率的方法,以及氯化钾泥浆体系和复合钻进技术在页岩气钻井中的应用。
The final hole depth of ChangYe parameter well -I is 3204.72m with complex formation and long coring section. The drilling construction is elaborated in well structure, drilling tools assembly, drilling equipment, bit drilling parameters and drilling fluid. This paper mainly introduces the methods of ensuring the high coring rate and the application of potassium chloride mud system and composite drilling technologies in shale gas drilling.
