摘要
本文从套管柱受轴向压力的情况入手,简要分析和补充了国外学者计算一维、二维、三维井身下的套管柱挠度的新方法。该方法利用固定端边界条件,把带扶正器的套管柱当作一连续梁来考虑。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。
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. Total lateral load is caused by weight of pipe sag,axial-load, iquid density difference and so on in cementing operations. Casing deflection can be controled by this new method,more accurate casing deflection and centralizer spacing can be obtained.
