Optimization Method of Suction Parameters of the Energy-saving in Rod Pumping Wells

Using the simulation methods for calculating dynamic parameters of rod pumping wells,the polished rod dynamometer card,crank torque,motor output power and system input power mathematical models were set up,and the system efficiency simulation models were improved.Basing on the constant pressure production,taking the least system input power as the optimization design objective function,considering the constraints,the optimization models of suction parameters of energy-saving in rod pumping wells were built....
