摘要
钻井液技术是保证钻井施工安全与快速成井关键技术之一。通过开展煤层气水平井井壁稳定研究,利用矿物分析、水化分散、膨胀性实验,结合现场应用效果,优选了煤层气水平井的钻井液体系,经过现场6口水平井的应用,未发生井下复杂情况,满足了煤层气水平井钻井安全要求。
drilling fluid technology is one of the key technologies to ensure drilling safety and rapid completion. The drilling fluid system of CBM horizontal well was optimized through the study of borehole stability of CBM horizontal well,the experiment of mineral analysis,hydration dispersion and expansibility,and the field application effect.
