%X In this paper the computer diagnostic system of the subsurface dynagraphs of sucker rod pumps is developed. It is composed of a digital dynamometer, a data acquisition interface, and a computer system. The subsurface dynagraphs are calculated and plotted according to the measured load and displacement from a polished rod on the ground. Then, the operation conditions of the whole pumping system can be monitored and diagnosed.
