Based on the unique geometry and mechanical movement of beam pumping unit, this paper presented a simple swing equation and computed motorial parameter, meanwhile under the conditions of the static load and inertial load of the polished-rod of a conventional pumping unit, it also presented an equivalent dynamic model of the pumping unit system and the type-curves of net torque of the crankshaft with the characteristic of inertial counterbalance having been computed, the model can provide a theoretical base for study on the other transient working parameters of beam pumping unit. Being satisfied with motion accuracy and boundary constraints, the optimization model of beam pumping unit is established. The simulated annealing algorithm with penalty strategy is adopted to solve the optimal model, so that optimization process was simplified and the global optimal solution is ensured reliably.
