ANALYSIS ON THE DYNAMIC PERFORMANCES OF THE VARIABLE SPEED OPERATING SYSTEM FOR THE BEAM PUMPER
摘要
Abstract
The technology of variable speed operation has been generalized to a certain degree in domestic oilfields;however,its present theoretical researches are relatively less.Therefore,the corresponding dynamic and vibration models were established.Through the solutions seeking of the models,the changes of the pumper performances before and after the speed variation were studied.The calculation results indicate that for the oil pumping system with the variable speeds,the peak value of the inertia torque Td decreases by 56.56%,and the equilibrium rule climbs by 56.68%;when the stroke frequency is less than 10 min-1,the vibration of the plunger changes slightly,when the stroke frequency is more than 10 min-1,the vibration amplitude is significantly increased.Besides,the wave amplitude of the input power curve of the pumping system decreases to a great deal,the peak of the operation power reduces by 70%.The researches prove that the variable speed operation of the oil pumper can greatly improve the dynamic performances of the system.关键词
