Abstract: This article deals with the application of reactive moment acting on the mid-point of continuous beam with double-span under uniform load to replace the one for drill collar above the stabilizer for pendulum assemblies in crooked boles.Equation is derived for the determination of the optimal location to place the stabilizer.An analytical formuia for straight deviation-holes is obtained,analogous to the one used in woods-lubinski method,with an error of about 5%.
摘要: 本文讨论了用相当均布载荷下的双跨连续梁中间支座上的反弯矩,近似地代替在弯曲井眼内钟摆组合钻具扶正器以上钻铤的反弯矩。并应用能量原理导出了弯曲井眼内确定钟摆组合钻具扶正器的最佳安装位置的超越方程。在斜直井内,可得到一解析公式,该公式与乌兹-鲁宾斯基方法相比,其误差在5%左右。
