摘　　要：本井使用Landmark软件进行套管摩擦系数反演和下入摩阻计算,分析不同尾管下入方式,优选钻杆和尾管全掏空+旋转下入方式,并采取加重钻杆倒装和送入管柱复配设计,克服了尾管在长延伸裸眼段中的高摩阻问题,解决了高水垂比大位移井采用常规尾管下入方式下放无悬重,无法下放到位的难题。Using Landmark software for this well doing casing friction coefficient inversion and down to the friction calculation,analysising under the liner into the different way,optimizing the way of rotating and hollowing of drill pipe and liner,and increasing the drill pipe inversion and into string distribution design,overcame the high friction problem of the liner in long open hole section,solved the liner into the hole problem in high water vertical ratio ERD well.
