摘　　要：针对油田新型水基动力无杆抽油系统在运行中动力缸易受到液压冲击的问题,开展了水基动力无杆抽油机动力学分析与研究。基于流体动力学理论,运用有限元分析方法进行加载过程中瞬态分析和相应的稳态分析,分析了稳态压力和流速分布及瞬态压力和流速随时间变化的过程,得到了不同状态下的流场分布情况。流体分析结果表明流体流动不对称,且加载输入功率不稳定,分析结果有利于进一步开展系统故障分析,并能够为之提供理论依据。Aiming at hydraulic impact problem of the cylinder in the new water-power based rod-less pumping system, the dynamics analysis and research are carried out. Based on the fluid dynamics, by using the finite element method, transient-state analysis in the process of loading and its corresponding steady-state analysis are continued. The changing process of the static pressure ,velocity distribution and the transient curve is analyzed; and the distribution of flow field is obtained. The result shows that the fluid flow is asymmetric and the load power is not stable, which is conducive to further system failure analysis and provides the theory basis for it.
