摘要
溱潼凹陷红页201井组以定向井方式开发页岩油,通过井身结构优化,形成二开制(变径)井身结构,优选高效钻头复合钻井技术(PDC)钻头实现钻井提速,使用偏心扩眼器应对上部井段缩径问题,优选高性能水基钻井液体系维持井壁稳定,实现红页201井组高效钻完井.
Abstract
The Hongye 201 well platform in Qitong Depression developed shale oil in a directional well,formed a two-string(variable diameter)well structure through well structure optimization,selected efficient PDC bit to achieve drilling speed,used eccentric reamer to deal with the problem of upper hole diameter reduction,selected high-performance water-based drilling fluid system to maintain wellbore stability,and realized efficient drilling and completion of Hongye 201 well platform.
