Abstract

The invention belongs to the technical field of oil field oil extraction, and particularly relates to a walking-beam-free-type pumping unit unloading device and a using method. The walking-beam-free-type pumping unit unloading device comprises a supporting base, two hydraulic cylinders, a supporting block, a load-bearing cross beam, a hydraulic station and a remote-control module; the two hydraulic cylinders are fixedly connected to the two ends of the supporting base, and the top end of each hydraulic cylinder is fixedly connected with a tray with a groove; the supporting block is located between the two hydraulic cylinders and provided with a hollow part, a supporting cross beam penetrates through the interior of the hollow part of the supporting block, and the two ends of the supportingcross beam are located in the grooves in the trays; the hydraulic cylinders are connected with the hydraulic station through high-pressure pipelines; and the remote-control module controls starting and stopping of the hydraulic station and thus controls lifting and descending of the hydraulic cylinders. The unloading problem of a walking-beam-free-type pumping unit is solved through a step-by-step lifting mode, unloading safety and using convenience of the walking-beam-free-type pumping unit are improved, the floor area is reduced, and the operation cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of oil production in oil fields, and in particular relates to an unloading device and a use method of a beamless pumping unit. Background technique [0002] Oilfield oil production mainly adopts mechanical oil production equipment, among which the pumping units are mainly beam pumping units and beamless pumping units. The beamless pumping unit is characterized by its simple structure, basically maintenance-free, long stroke and low , Large load performance can be widely used. [0003] The unloading method of the beamless pumping unit is carried out by using a winch or a hoisting vehicle in cooperation with the unloading wire rope. The hoist is fixed on the upper platform of the pumping unit. One end of the wire rope is fixed to the hoist, and the other end is fixed on the pin on the top of the platform after bypassing the lug guide wheel on the top of the counterweight box. Due to the low safety factor of t...
