Under the operation conditions of a jet pump system in one well considered, the maximum average operation efficiency of the jet pump system over a range of flowing bottomhole pressures is taken as the objective function on the premise of meeting the production requirements. The optimum model is set up, considering four optimum variables, that is, the ratio of nozzle area to throat area, piston pump horsepower, piston pump pressure, and tubing size. The model includes twelve constrained conditions which are governed by caviation characteristics and operation performance of a jet pump and can be determined by complicated iterative calculation of jet pump performance.. The technique of mixed-discrete nonlinear optimization is used to solve the model in order that a jet pump system matches optimally. The optimum matching technique lays the theoretical foundation for the general layout of a jet pump system of a well.
