Abstract: In order to minimize operating costs and maximize oil production, a quick and accurate identification of down-hole problem is essential in rod pumping system. This paper proposed a new integrated intelligent technology for diagnostic the fault of the sucker rod pumping system, which is integrated conventional knowledge inference, artificial neural networks and conventional mathematics algorithm, and in detail, introduced the whole developing procedure of an intelligent diagnosis system, including system designing, composing, function and realization. This method can do a faster and better job than conventional technologies. It is presented a new way for intelligent diagnostic the fault of the sucker rod pumping system.
