Energy saving oil pumping unit

Abstract

The invention discloses an energy saving oil pumping unit, wherein the bottom of the oil pumping unit body is provided with a base; a support is installed on a top of the base; a chute is opened on atop end of the inner side of the support; a slide plate is installed inside the chute; a second Y355 electric motor is installed on one end of the top of the slide plate; a transmission shaft is fixedly connected to one end of the second Y355 electric motor; a speed reducer is installed at one end of the transmission shaft; a connecting shaft is fixedly connected to one end of the speed reducer; areel is installed at one end of the connecting shaft; a wire rope is arranged around the outer side of the reel; a sucker rod is installed at the bottom end of the wire rope, and a hydraulic cylinderis installed at the bottom of the slide plate; the top of the hydraulic cylinder is provided with a telescopic rod, and a top plate is mounted on the top of the support. The hydraulic cylinder of thepresent invention is hinged to the slide plate by a telescopic rod. The hydraulic cylinder can move the slide plate up and down through the telescopic rod, thereby realizing the change of the strokeof the pumping unit body. The operation is simple and quick, and it is convenient to freely adjust according to the needs, which expands the applicable range of the pumping unit body and improves itspracticability.

Description

technical field [0001] The invention relates to the technical field of an oil pumping unit, in particular to an energy-saving oil pumping unit. Background technique [0002] The oil pumping unit is a kind of machinery and equipment for oil extraction. Most of the oil fields in my country are low-permeability, low-energy and low-yield oil fields. Upgrading from the formation, changing oil with water or electricity is the reality of my country's oil fields. Therefore, electricity costs account for a considerable proportion of my country's oil production costs. Long-term low-cost advantages, energy saving and consumption reduction have become an unavoidable proposition for oilfields to stabilize and increase production. The pumping units currently used are mainly beam pumping units. Although this type of pumping unit has a simple Reliable and other advantages, but it still has the disadvantages of bulky size, large start-up impact, high power consumption, poor balance effect, etc...

[0002] The oil pumping unit is a kind of machinery and equipment for oil extraction. Most of the oil fields in my country are low-permeability, low-energy and low-yield oil fields. Upgrading from the formation, changing oil with water or electricity is the reality of my country's oil fields. Therefore, electricity costs account for a considerable proportion of my country's oil production costs. Long-term low-cost advantages, energy saving and consumption reduction have become an unavoidable proposition for oilfields to stabilize and increase production. The pumping units currently used are mainly beam pumping units. Although this type of pumping unit has a simple Reliable and other advantages, but it still has the disadvantages of bulky size, large start-up impact, high power consumption, poor balance effect, etc., can not meet the needs of energy saving, and has poor practicability
