Analysis on simulation for the slide-way designing of URRS' whipstock;

径向井造斜器滑道设计的仿真分析

At present, the key problem in domestic test is that the drill pipe is difficult to move through the slideway of whipstock.

仿真研究对指导造斜器设计和施工工艺的设计有积极意义。

Several whipstock constructions are analyzed and some anchoring technologies are studied in detail,and some su.

造斜器是一种开窗侧钻工具,大量用于侧钻井、水平井和分支井作业,是分支井作业的关键工具之一,其坐封技术也是分支井的关键技术之一,其坐封效果、开窗质量决定了后续作业的成败。

Based on the method of equilibrium curvature, built-up rate of h.

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。

In controlled directional drilling technology, whipstocking intensity of theoritical calculation is smaller than that of practice.

定向钻进技术中 ,按理论计算可选择的造斜强度是偏小的 ,通过采用提高钻杆柔性等技术方法 ,实际可选择的造斜强度大大提高 ,经实践证明效果显著。
