摘要
建立了竖直井安装扶正器的油管力学模型，给出了油管任意横截面轴力的计算方法，导出了相邻扶正器之间油管失稳的临界状态方程。以油管不发生失稳为条件，确立了从泵端向上安装扶正器的间距的计算方法，并以中原油田卫１１５井为例进行了计算。
A mechanical model for installing tubing stabilizer in vertical well is established, and a method of calculating axial force in tubing is presented. A buckling equation for two tubing stabilizers is derived An interval for spacing stabilizer along the tubing is determined As an example, the interval with Wei 115 in Zhongyuan oilfield is computed
