Abstract

The new optimal adjustment method on stroke of the digital pumping unit is proposed in this paper after analysis the main disadvantages of the existing digital pumping unit on adjustment speed. The new method is based on the change of the area of the indicator diagram. According to the change of the area of the diagram, the stroke of the pumping unit is optimized in the optimization module. The digital optimization module is set up between the RTU and the frequency converter of the existing digital pumping unit. The dynamic data compression algorithm is used for real-time access on the module, which improves the real-time performance of the system. And the module has the function to communicate with the control with the RTU and the frequency converter. So this pumping unit has the intelligent ability to control pumping speed, and no longer relies on the host computer. Tests about the module had been carried out at the oil production site and the changes of the indicator diagram and the adjustment of the stroke was recorded. The experimental results have shown that the method is feasible. The optimization method on stroke of the digital pumping unit is in accordance with the changing trend of the supply capacity of oil well.
