Abstract: There are many factors influencing the choice of artificial lift methods,most of which aredifficult to describe quantitatively. The artificial lift methods in China oil fields are generallychosen by qualitative analysis or analogy. All factors affecting the choice of artificial liftmethods are considered, a general model for optimizing the lift methods are established.Through a large amount of investigations,the matrixes of weight factor and attaching extentare set up by the statistical method.A computer program is complied,the results of its application indicate a quite good consistency with practice.
