The invention discloses an electric submersible plunger pump detection device and a detection method thereof. The electric submersible plunger pump detection device is designed for guaranteeing the efficient running of the electric submersible plunger pump in the oil well lifting process. The detection device is connected with an energy storage tank, first and second valves, first and second pressure transmitters and the electric submersible plunger pump to be tested by use of a pipeline, and connected with an electric control box and a motor located in a simulative well by use of cables; the pressure and flow values of a liquid, the frequency of stroke of the pump and the working electric frequency data of the motor are obtained by virtue of operations under simulated field conditions. The electric submersible plunger pump detection device is capable of excellently simulating the field conditions and capable of accurately measuring the operating parameters and the maximum lifting force of the electric submersible plunger pump under different working frequency, and pump efficiency and displacement under different frequencies of stroke, thereby guaranteeing safe and efficient running of the electric submersible plunger pump in the oil well lifting process.
Description
technical field [0001] The invention relates to a detection device of an electric submersible plunger pump and a detection method thereof, and belongs to the technical field of mechanical oil recovery for petroleum development. Background technique [0002] Because the driving mode of the electric submersible plunger pump is completely different from that of the pumping unit plunger pump, the existing detection method for the pumping unit plunger pump cannot detect the electric submersible plunger pump. Before using the electric submersible plunger pump, it is necessary to accurately grasp its pump efficiency and displacement under different strokes and the maximum lift at different operating frequencies, and finally determine its pump type and pumping depth, combined with the oil well on site Specific data can ensure its safe and efficient operation in oil well lifting. Contents of the invention [0003] The object of the present invention is to provide an electric subme...
