Description

technical field [0001] The invention relates to a device and method for analyzing the working efficiency and balance degree of a pumping unit, and belongs to the technical field of working analysis of the pumping unit and on-site data collection and analysis of digital oil fields. Background technique [0002] The analysis of the working efficiency and operation balance of the pumping unit is a detection technology with great energy-saving significance. Due to the continuous wear and tear of the mechanical structure of the pumping unit and the change of the downhole working conditions at any time, the working efficiency of the pumping unit increases with the The running time will gradually decrease, thereby increasing the energy consumption of the pumping unit. If accurate detection can be realized, then the pumping unit can be balanced and adjusted according to the detection results, the efficiency (or balance degree) of the pumping unit can be restored to more than 80%, an...
