Abstract

Abstract: The unique phenomena at any cross section of EULER compressive bar under the zero bending moment is analyzed.With this situation,any amount of axial load can be applied to compressive bar of arbitrary length without bending.The laboratory test has proven that theoretical analysis is practical.On this basis,a new kind of unbending drill collar tool has been designed,which is probably to be a new kind of inclination preventive tool.

Key words: deviation control, drill collar, simulation test, inclination preventive tool

摘要： 从理论上分析了欧拉压杆任意截面上弯矩为零的状态下所出现的奇异现象.在此状态下可在任意长度的压杆上,加任意大小的轴向载荷,而不产生弯曲.通过室内模拟试验证明,理论分析是符合实际的.为此,设计了一种压不弯钻铤装置,此装置有可能成为防斜打直的一种全新的井下钻具.
