摘要
本文综合分析了定向井中有杆泵抽油的抽油杆柱、液柱和油管柱的受力情况，得到一组描述其运动规律的偏微分方程组，用有限差分法进行了求解。该模型可对定向井有杆泵抽油进行动态分析和优化诊断。
In this paper the forces on the sucker rod string,tubing and liquid column in a sucker rodpumping system in a directional well have been comprehensively studied.A set of partial differ-ential equations describing the movement in the pumping system has been solved by the finite dif-ference method. This mathematical model can be applied to giving a dynamic analysis and anoptimizing diagnosis of the sucker red pumping system in a directional well.
