Abstract
In order to know something about the flow of the fluid in sucker rod pump and obtain guidance for
deciding the pump’s size and structure design, the fluid flow was calculated by using the K −ε two-
equation model. Based on the finite method, we analyzed several situations in a pumping period.
Introduction
It is generally understood that different kinds of fluid flow are often dealt with, such as liquid moving to
and fro in the pump, vertical or declining motion of single-phase and multiphase fluid in the oil pipe, and so
on, when the sucker rod pumping system is working. Due to plexity of pump’s inner structure and
the reciprocation of liquid movement in the sucker rod pump, the problem of analyzing the fluid flow in a
pump is plex and not yet entirely understood. Recently, because the study of reciprocation of
liquid movement in the sucker rod pump is infrequent and liquid movement law is not yet entirely
understood, numerical analysis has been applied to the study of fluid flow in pump by the method of finite
element analysis with the help of ANSYS.
In order to analyze the fluid flow in a sucker rod pump, several pump valve and piston locations in an oil
pump circulation were selected to set up putational models to analyze. In this paper, the movement
of crude oil that lies in the valve channels and orbicular channels of the pump is analyzed carefully. As a
consequence, the liquid movement law can be obtained in an oil pump circulation according to the previous
several spe
