The invention relates to a pumping unit polish rod displacement testing method and testing device. The pumping unit polish rod displacement testing device is mounted on a beam hanger of a pumping unit and used for detecting changes of barometric pressure within the reciprocating running range of a polish rod of the pumping unit in real time to obtain a group of dynamic data corresponding to the changes of the barometric pressure, and the displacement of the polish rod of the pumping unit is calculated according to the maximum difference of the changes of the barometric pressure within the running range of the polish rod. According to the structure of the testing device, a barometric sensor, a data processing circuit board, a data output circuit board and a power circuit are installed in a shell, the barometric sensor is connected with the data processing circuit board, the data processing circuit board is connected with the data output circuit board, and the power circuit provides power. The pumping unit polish rod displacement testing device is novel in structure and convenient to operate. The pumping unit polish rod displacement testing device thoroughly abandons a complex mechanical structure and a stay wire of a traditional displacement testing device, and the testing method is a brand new displacement testing method.
Description
Technical field [0001] The invention provides a novel pumping unit polished rod displacement test sensor, in particular to a test method and testing device for the polished rod displacement of an oil pumping unit. Background technique [0002] The test of the indicator diagram of the pumping unit well is an important method in the daily management of the oil well. According to the measured indicator diagram, the working status of the pumping unit can be understood so that the engineering and technical personnel can take other measures in time to ensure the stable production of the oil well. . [0003] The indicator diagram of a pumping unit well is a closed graph formed by the change of the load of the pumping unit's suspension point with the displacement of the polished rod. From the graph, the maximum and minimum loads, strokes, strokes and other data can be known. [0004] At present, there are four test methods for pumping unit polished rod displacement stroke and stroke rate: r...
