A control method of stroke extraction machine running distance positioning, it is the use of connection in the absolute encoder end of the drive shaft, encoding the drive shaft rotation angle position of oil when the machine is running, and enter the programmable controller, then the encoding signal into the stroke position signal produced by the programmable controller according to the machine; the position signal encoder transmission, rotary motor, variable instruction two directions for reciprocating rope hanger. The invention can realize the accurate adjustment of the stroke distance and improve the oil production efficiency.
