Abstract

The invention discloses a processing method and device for motion displacement of an oil pumping unit. The method comprises the steps that according to air pressure data obtained after low-pass filtering, a dead point maintaining area in at least one operation stroke of the oil pumping unit is determined, wherein the air pressure data at least comprise air pressure parameters of the oil pumping unit in the operation stroke; the dead point of acceleration data after low-pass filtering is determined according to the dead point maintaining area, and the operation cycle of the oil pumping unit is determined according to the dead point, wherein the acceleration data at least comprises acceleration parameters of the oil pumping unit in the operation stroke; the acceleration data after low-pass filtering are detected and adjusted according to the air pressure data after low-pass filtering so as to verify and adjust the operation cycle of the oil pumping unit; and the motion displacement of the oil pumping unit is determined according to the adjusted acceleration data in the operation cycle of the oil pumping unit. According to the processing method and device for the motion displacement of the oil pumping unit, the technical problem that the motion displacement calculation of a pumping unit in the prior art needs a large amount of data processing and cannot be applied to low-power-consumption application scenarios is solved.

Description

technical field [0001] The invention relates to the technical field of state monitoring of oil pumping units, in particular to a method and device for processing movement displacement of oil pumping units. Background technique [0002] At present, dynamometers that collect working load-displacement work diagrams of pumping units mostly use acceleration sensors and load sensors to collect displacement and force. The acceleration sensor realizes the calculation process from acceleration to displacement through integration algorithm after filtering. The pumping unit reciprocates in the vertical direction, so the determination of the up and down stroke of the pumping unit is very critical. As the boundary of the upper and lower strokes, the accuracy of the calculation of the upper and lower "dead points" will directly affect the determination of the stroke times of the power map. [0003] As the oilfield exploitation enters the middle and late stage, a large number of oil well...
