1) casing deflection
套管挠度
1.
The paper analyzes and replenishes the new method of casing deflection calculation in directional well ad-vanced by some foreign scholar advanced,which think of casing string as a continuous beam in the directional wellbore and use the fixed-ends boundary condition to calculate casing deflection for a span of casing be-tween two centralizer for 1D,2D and 3D wellbore.
通过此法可更加精确地求出套管挠度、套管扶正器最佳间距。
2) bending deflection of pipe
管道挠度
3) casing string flexural de-form
套管柱挠曲变形
4) nonrigid ventricular cannula
挠性心室套管
5) pipe cutting
管道挠度法
6) deflection of pipe line
管线的挠度
补充资料：挠度
细长物体或薄物体在受力或受热后弯曲变形程度的度量。细长物体（如梁或柱）的挠度是指在变形时其轴线上各点在该点处轴线法平面内的位移量。薄板或薄壳的挠度是指中面上各点在该点处中面法线上的位移量。物体上各点挠度随位置和时间变化的规律称为挠度函数或位移函数。通过求挠度函数来计算应变和应力是固体力学的研究方法之一。
