| 摘 要： | 通过对比斜直井与竖直井游梁式抽油机悬点载荷,得出了在大角度斜直井条件下上冲程悬点载荷不会有很大变化,而下冲程悬点载荷却要显著减小的结论。为了使斜直井抽油机能合理地工作,对抽油杆柱受力进行了分析,并论述了计算斜直井游梁式抽油机冲程长度和冲次的方法。

Pumping parameters for pumping units on slant Straight holes |
| |
| Abstract: | A comparision between the polished rod load of a beam pumping unit on a slant straight hole and that on a vertical straight hole shows that, on high-slant straight wells, the polished rod load on the upstroke changes slightly, while that on the downstroke reduces prominently. In order to make the pumping unit work on a slant straight hole under favourable condition, the stress on sucker rod string is analyzed and the method for calculating the stroke length and pumping speed of a beam pumping unit for slant straight holes is discussed. |
