| 摘 要： | 本文根据动力学原理,考虑井眼轨道、抽油杆柱构成、抽油杆与油管的滑动磨擦力及油液的内摩擦力,采用微元矢量分析方法,建立了定向水平井抽油杆柱纵向振动的微分方程,给出了井下动态参数诊断的定解条件。建立了该模型的差分解,编制了计算机软件,并在大庆油田采油五厂得到了较成功的应用。

| Abstract: | Based on the dynamics principle,differential equations of longitudinal vibfation of rod stringand boundary conditions for dynamical analysis of sucker rod pumping system in directional well havebeen established by tuking account of well trajectory,construction of rod string,friction force betweenrod string and tubing,and viscous force of well fluid etc. in this paper. The said models are solved by finite difference method and the revelant computer software is worked out. This technique is applied in the5th production department of Daqing oilfield. |
