摘　　要：对有杆抽油泵泵阀运动规律的研究和确定抽油泵泵阀筒内液体压力的分布是提高抽油机井系统效率研究的关键性课题。作者在Matlab软件平台上,利用Simulink分析器对抽油泵泵阀的运动规律进行计算机仿真研究,结果表明,抽油泵泵阀筒内液体压力的分布具有明显的"非线性",抽油泵泵阀运动亦有非线性规律,而且具有"抖动跳跃"现象。这为提高抽油机井的系统效率研究提供了有益借鉴。It is the key study how to make sure the pressure distribution of liquid in the pump barrel and to study the pump valve-bali＇s movement to improve the systematic efficiency. This paper presents a new method for simulating the pump valve-bali＇s movement and the pressure distribution of liquid in the working barrel using the Simulink model on the Matlab software. By the study, the authors find that the pressure distribution is characterized by ＂nonlinear＂ and the motion of pump valve is the same, too. To prevent the leakage of the motion of a pump valve and the declining of pump effect, people must let this kind of phenomenon does not occur. This study will be beneficial to the study of the systematic efficiency of pump well.
