The invention belongs to the technical field of load shedding devices, solves the technical problems that in the prior art, a pump cylinder on a load shedding device is prone to stress deformation and breakage, the pump cylinder is inconvenient to center, and the service life is short, and provides a pumping well load shedding device and a production method. Comprising an adapter upper connector, a long plunger, a short pump cylinder, a long pump cylinder, a short plunger and an adapter lower connector which are sequentially connected from top to bottom, the outer side face of the adapter upper connector is sleeved with an outer pipe upper connector, the outer side face of the lower end of the short pump cylinder is sleeved with an outer pipe middle connector, and the outer side face of the lower end of the long pump cylinder is sleeved with an outer pipe lower connector. A short connection outer pipe is connected between the outer pipe upper connector and the outer pipe middle connector, a long connection outer pipe is connected between the outer pipe middle connector and the outer pipe lower connector, the short pump cylinder is arranged in the short connection outer pipe, and the long pump cylinder is arranged in the long connection outer pipe. The pumping well load shedding device and the production method have the advantages that the pump cylinder is protected, the service life of the pump cylinder is prolonged, and the service life is long.
Description
technical field [0001] The invention relates to the technical field of load reducers, in particular to a load reducer for pumping wells and a production method. Background technique [0002] At present, the main mining methods used in oil extraction are to use large-displacement oil well pumps, electric submersible pumps, etc. to extract liquid, and to use fiberglass rods, carbon fiber rods, etc. for deep pumping. Due to the restriction of the rated load of the donkey head of the pumping unit and the weight of the sucker rod, the depth of the lower pump is limited to a certain extent and it is difficult to meet the needs of oilfield development. Then there are technologies such as lowering the electric pump to extract liquid and lowering the glass rod for deep pumping. Resulting in high energy consumption, high cost and low benefit for crude oil production. The pumping well load reducer technology is a new supporting technology for pumping well mechanical recovery, which ha...
