Problems solved by technology

[0002] At present, the main oil production mode in oil field production is mechanical oil production, and the oil production equipment used is mainly beam pumping unit. With the development of petroleum technology, scientific and technological personnel have also developed some other types of oil production equipment, such as chain pumping unit 1. Although the electric drum pumping unit is not very mature, it can be seen occasionally in oil fields. Some people have also done hydraulic pumping units. However, due to structural defects, the hydraulic pipeline is complicated and there are many hydraulic components. The hydraulic control is unreasonable, which makes the halfway break
The above-mentioned beam pumping units, chain pumping units and electric drum pumping units have complex mechanical transmission systems, low system efficiency, poor relative energy saving effect, and inconvenient management

Abstract

An energy-storage lifting intelligent hydraulic pumping unit is formed by a hydraulic power device and a transmitter, which uses a step motor to control a three-way ball valve as unique hydraulic element used in steering control of the pumping unit, while one opening is connected with the outlet of the hydraulic pump, one opening is connected with a bottom inlet of a piston cylinder, and another opening is connected with a hydraulic oil pot, the inlet of the hydraulic pump is connected with an outlet of the hydraulic oil pot, the air pot contains a sliding sealing plug or the air pot contains an air bubble insulated from the hydraulic oil, the upper end of the piston rod is disposed with a block base arranged with one or three blocks fixed on the block base via a support, the hydraulic room is fixed with a block to form a strike-variable block group, one end of hair line is connected with a well smooth rod via a suspender and a square clamper while another end via the strike-variable block group is fixed on the hydraulic room. The invention has reliable operation and energy saving.

Description

1. Technical field [0001] The invention relates to an energy storage type skid-mounted intelligent hydraulic pumping unit used in oil exploitation. 2. Background technology [0002] At present, the main oil production mode in oil field production is mechanical oil production, and the oil production equipment used is mainly beam pumping unit. With the development of petroleum technology, scientific and technological personnel have also developed some other types of oil production equipment, such as chain pumping unit 1. Although the electric drum pumping unit is not very mature, it can be seen occasionally in oil fields. Some people have also done hydraulic pumping units. However, due to structural defects, the hydraulic pipeline is complicated and there are many hydraulic components. The hydraulic control is unreasonable, causing the car to break halfway. The above-mentioned beam pumping units, chain pumping units and electric drum pumping units have complex mechanical tran...
