Abstract: The simulation methods for calculating dynamic parameters of rod pumping system,such as polished rod dynamometer card,crank shaft torque,motor input power,displacement coefficient and effective power,were systematically improved,and the mathematical models for simulating system efficiency were set up.By using the improved suction parameters containing polished rod stroke,pump plunger diameter and pump depth changed,the mathematical models of simulating system efficiency were developed according to coordination equation of well production.The computer simulation programs for system efficiency of rod pumping wells were developed.According to a lot of simulated results,the effective methods for enhancing the system efficiency are presented.

Key words: rod pumping well, system efficiency, suction parameter, mathematical model, computer simulation
