摘要
通过对有杆泵抽油系统进行井身曲线的空间分析,运用空间解析几何原理,求得相邻单位元的轴向夹角,在此基础上进行节点受力与位移的动力学分析,建立了有杆泵抽油系统的修正模型。并以马岭南 29-11(1993/11/09)的井身曲线为例,计算对比了模型与传统模型的区别,结果表明方法简单易行,也没有计算量的显著增加,且可以极大地提高计算精度。
In this paper, based on the methods of space analytic geometry, the angle between the adjacent sections was analysed and computed, which was used in decompounding of force and displacement of joints of pumping system. Further, a modified mathematical model is proposed. And the model was employed in the dynamic analysis of the Malingnan29-11 Well (1993/11/09). The results showed that the modification could greatly improve the accuracy of the original models of sucker-rod pumping system without any addition of the computational cost. And it could be easily applied in the analysis of different pumping systems.
