前言 确定在一定抽汲方式下抽油机悬点的最大载荷是选择抽油设备及抽油技术设计中必须首先解决的问题。已有的计算方法不是因过于简化而误差较大,就是虽然较精确,但计算比较繁琐。本文将从抽汲过程中抽油杆柱的纵向振动出发,提供一种计算悬点最大载荷的简化方法,并与实测资料及其它计算方法进行比较。 Preface determines the maximum load of pumping unit under a certain pumping mode is the first problem to be solved in the selection of pumping equipment and pumping technology design. The existing calculation method is not over simplified and the error is larger, that is, though more accurate, the calculation is rather cumbersome. Starting from the longitudinal vibration of sucker rod during pumping, this paper provides a simplified method to calculate the maximum load of suspension point, and compares it with the measured data and other calculation methods.
