Research and application of key drilling and completion technologies of Hongye 201 well platform in Qintong Depression
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.
