Method for adjusting effective stroke of double-well pumping unit

The invention relates to a method for adjusting the effective stroke of a double-well pumping unit. Mainly solves the problems of high production cost and inconvenience in adjustment of the stroke adjustment method of the existing one-machine double-well pumping unit. The method is characterized in that the stroke ratio of actual requirements of two wells is calculated according to the actual liquid production capacity of a double-well pumping unit and the pump diameter of an oil well pump, which well needs a small stroke is judged according to the ratio, and a sucker rod of the well is lifted up, so that a plunger of an underground pump part is lifted out of a pump cylinder, and therefore the effective stroke is reduced, and the purpose of working condition matching is achieved. The method does not need operation, the whole process only needs to lift the sucker rod to drive the underground pump plunger, the operation is safe and simple, and the labor intensity of personnel and the production cost are greatly
