Dynamometer Card Analysis
Downhole Dynamometer Card is the main diagnostic measure tool of the Sucker Rod Pump. It is formed by the values of position of the pumping unit and the pressure in the connection junction of the sucker rod and the pump. The shape of dynamometer card reflects the working conditions of sucker-rod pumping systems, and different conditions can be indicated by their typical card characteristics.
