Theoretical And Experimental Study Onthe Influene Of Gas To Performance Of Oil-Well Pump

In pumping-pump system, the oil-well pump efficiency have a greater iMPact on the whole systemic efficiency. In the oil production process, there is an inevitable phenomenon of the existence of gas into the pump, the pump gas directly affects the pump efficiency. Therefore, from both theoretical and experimental study of gas content on the iMPact of pump efficiency to guide the production and management of pumping wells, and provides a theoretical basis for the structural optimization of pump design, to improve the systemic efficiency of pumping well, save energy, improve comprehensive development effective field is important.Based on one-dimensional equations of fluid into the pump, gas equation of state, full of coefficient equation, establish the mathematical model of fluid into the pump. Through the VB programming, simulating gas wells impact on pump performance in different conditions of the situation. In a certain gas content, different submergence depth, different gas-liquid ratio, different strokes, different factors on impulse pump is full of second-class coefficient, pump pressure, surface speed, instantaneous volume of leakage were analyzed, obtained the working parameters of the law of pump performance.The completion of the filling simulation test function is based on in the original analog multi-functional test system of rod pump, Routine tests carried out tests (without air test) and filling test diagram testing and analysis. From test of experiment and calculation, obtain the relationship between the submergence depth, gas content, stroke, stroke of the pump and coefficient of discharge, the theoretical simulation results are verified.
