Problems solved by technology
[0002] Oilfield oil production mainly adopts mechanical oil production equipment, among which the pumping units are mainly beam pumping units and beamless pumping units. Small size can be widely used, but the existing electronically controlled reversing beam pumping unit drives the synchronous belt, pulley, and roller through the motor, and the cost is relatively high, and the reducer matched with the beam pumping unit is prone to oil leakage during use or splash, causing environmental pollution on the oil production site and increasing the cost of oil production in the oil field

The invention relates to the technical field of oil field oil extraction, and particularly relates to an electric control reversing direct-drive beam-pumping unit. The electric control reversing direct-drive beam-pumping unit comprises a base, a support and a synchronous belt, wherein the lower end of the support is fixedly connected with the base, and the upper end of the support is rotationally connected with a walking beam through a support; a horse head is arranged at the near end of a well mouth of the walking beam, and a motor is arranged at the far end of the well mouth; a lifting rope is arranged on the outer arc section of the horse head; the motor is fixedly connected with the walking beam; the synchronous belt is wound around belt wheels arranged on the two sides of the motor and engaged with the belt wheels; one end of the synchronous belt is fixedly connected with the base, and the other end of the synchronous belt is fixedly connected with a weight box; the motor is connected with a control cabinet through a signal line and a power line; and the motor arranged on the walking beam drives the synchronous belt to pull the walking beam, the walking beam and the horse head swing up and down with the support as the fulcrum, and safe and environment-friendly oil extraction is achieved.
Description
technical field [0001] The invention relates to the technical field of oil recovery in oil fields, in particular to an electronically controlled reversing direct-drive beam 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. Small size can be widely used, but the existing electronically controlled reversing beam pumping unit drives the synchronous belt, pulley, and roller through the motor, and the cost is relatively high, and the reducer matched with the beam pumping unit is prone to oil leakage during use Or splash, causing environmental pollution on the oil extraction site and increasing the cost of oil extraction in the oil field. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention provides an electronically controlled reversing direct-drive beam pumping unit, ...
