Problems solved by technology

[0002] At present, there are many types of pumping units in domestic and foreign oil fields, but most of them are large-scale, high-energy-consuming and expensive models. In recent years, all major oil fields have improved pumping units in terms of energy saving and oil production. However, the power consumption is not reduced, and the investment is also large.

Abstract

The invention relates to cluster-well calandria oil pumping equipment, in particular to an energy-saving pumping unit, and two energy-saving pumping units can simultaneously be driven by a set of powers. The energy-saving pumping unit comprises a hydraulic system (1), a valve (1-1), a pipe (1-2), a welding joint (21), a pipe joint cap (20), and the like, and the energy-saving pumping unit is characterized in that a base packing box (3) passes through a piston rod (2) and is hermetically connected with the piston rod (2) by shaft HBTS (27), the lower end of a connecting cylinder (4) is in threaded connection with the base packing box (3), a packing gland (5) is respectively fixed on the upper end of the base packing box (3) and the lower end of a lower cylinder cap (6) by two hexagon-headed bolts (28), a dustproof ring (26) is arranged in the packing gland (5), the upper end of the connecting cylinder (4) is in threaded connection with the lower end of the lower cylinder cap (6), a guide belt (25) is arranged in the lower cylinder cap (6), and a lateral hole of the lower cylinder cap (6) is in threaded connection with a welding joint (21). The invention has the advantages of small host volume, light weight, simple structure, less material consumption, low cost, and low one-time equipment investment.

Description

technical field [0001] The invention belongs to the oil production equipment of the cluster well calandria pump, and in particular relates to an energy-saving pumping unit in which two sets of power are simultaneously driven by one set. Background technique [0002] At present, there are many types of pumping units in domestic and foreign oil fields, but most of them are large-scale, high-energy-consuming and expensive models. In recent years, all major oil fields have improved pumping units in terms of energy saving and oil production. But it does not reduce the power consumption, and its investment is also large. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned technical deficiencies, and provide an energy-saving, small-volume, light-weight, low-cost, easy-to-maintain energy-saving pumping unit that can be directly installed on the wellhead. [0004] The technical solution adopted by the present invention to solve...
