分析了不同井眼曲率和不同弯角下120mm大角度单弯螺杆钻具组合应力分布情况,最大等效应力随着曲率的增加先减小后增大,随着弯角的增大而增大;采用平衡曲率法,对大角度单弯螺杆造斜率进行了计算。
To meet the demand of higher built-up rate,single-bending screw drill tool with large angle is used during the drilling of the moderate-and short-radius horizontal well.
钻中短半径水平井,在采用弯角较大的单弯螺杆钻具以满足高造斜率的需要时,由于套管内径较小,螺杆钻具钻头处位移比较大,螺杆钻具能否顺利通过直井段是钻中短半径水平井面临的一个重要问题。
