Abstract
A twin-well column pumping unit comprises an upright column and a beam hanger suspended on both sides of the upright column through a steel wire rope group; the beam hanger is connected with the upper ends of pumping rods on both sides of the upright column, an upper beam is fixed on the top of the upright column, a driving device is fixed on the upper beam, a friction wheel is mounted on the driving device and is connected with a tractor of the driving device, an upper pulley and a lower pulley are mounted on an adjusting rail of the upper beam, a steel wire rope pre-tensioning device is suspended on the steel wire rope on both sides of the friction wheel; the beam hanger, the upper pulley, the lower pulley, the driving device and a combined counterweight are connected together through a steel wire rope; the driving device drives the pumping rods on both sides to move up and down, during single well maintenance process, the adjusting rail of the upper beam moves to save space for the maintenance hoisting of the well head upper side, the combined counterweight is suspended on one side of the maintained well and the well on the other side works; the twin-well column pumping unit has the advantages that the stroke frequency can be adjusted in real-time, and the other well during the single well maintenance process still can work normally.
Description
Technical field
The present invention relates to a kind of oil field oil pumper, be specifically related to a kind of twin-well column pumping unit.
Background technology
There is very strong blowing ability in China oil field unlike oil field, the Middle East, mostly be low energy, the stripper field of hyposmosis.Changing oil or change oil with water with electricity is the production status in China oil field, and the electricity charge have accounted for sizable ratio in the China's oil cost of winning.According to statistics: the electricity charge expenditure in the average crude oil cost per ton accounts for 20～30%, and the electricity charge expenditure in the local field produces cost is bigger.Because domestic oil pumper is seldom having big innovation aspect frame for movement and the control system, the operational efficiency of oil pumper is low especially, and average efficiency only is 25.96%, and external average level is 30.05%.Domestic present energy-saving beam pumping unit mainly comprises non-synchronous crank balance oil pumper, forward type oil pumper, two horse head oil pumpers etc.Though various forms of energy-saving beam pumping unit equipment have all reached the effect more energy-conservation than conventional pumping unit, but still do not bring into play energy-saving potential to greatest extent, be embodied in: the stroke jig frequency can not be adjusted in real time; Existing " a machine twin-well " formula oil pumper is when individual well keeps in repair, and another mouthful well can not carry out operate as normal.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this invention is to provide a kind of twin-well column pumping unit, having the stroke jig frequency can adjust in real time, and the advantage that individual well another mouthful of when maintenance well still can operate as normal.
In order to achieve the above object, the technical scheme taked of the present invention is:
A kind of twin-well column pumping unit, comprise column 1, polished rod eye 2 is suspended from column 1 both sides by wire rope group 3, polished rod eye 2 is connected with the upper end of the sucker rod 11 of column 1 both sides, top rail 4 is fixed on the top of column 1, drive unit 5 is fixed on the top rail 4, drive unit 5 comprises friction pulley 6, friction pulley 6 is connected with the traction machine of drive unit 5, top sheave 7 and lower sheave 8 are installed on the adjustable track of top rail 4, wire rope pre-tightening apparatus 9 hangs on the wire rope of friction pulley 6 both sides, polished rod eye 2, top sheave 7, lower sheave 8, drive unit 5, combined counterbalance 10 links up by wire rope.
Opening form is adopted at described top rail 4 two ends.
Described wire rope pre-tightening apparatus 9 is made up of pulley and the heavy frame of extension.
Described friction pulley 6 adopts after-combustion mode lay winding wire ropes.
Operating principle of the present invention is:
After the raw payload balance of the equipment of adjustment both sides, traction machine on the drive unit 5 drives friction pulley 6 and rotates and reverse, the rotating and reverse of friction pulley 6 drive wire rope just around and back-roll, wire rope drives polished rod eye 2 by top sheave 7 and moves up and down, and then drive both sides sucker rod 11 moves up and down, in this process, the polished rod eye of the side that sucker rod 11 load are big drives combined counterbalance 10 by lower sheave 8 and moves up and down, in the individual well maintenance process, utilize the adjustable track of top rail 4 to move top sheave 7, lower sheave 8, be the maintenance lifting slot milling of well head top, at maintenance oil well one side mounting combined counterbalance 10, the opposite side oil well puts into operation.
Because twin-well column pumping unit directly drives by traction machine, and adopt open type structure top rail, can adjust in real time so have the stroke jig frequency, and the advantage that another mouthful well still can operate as normal during the individual well maintenance.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, a kind of twin-well column pumping unit, comprise column 1, column 1 usefulness stone bolt is fixed on the basis, polished rod eye 2 is suspended from column 1 both sides by wire rope group 3, polished rod eye 2 is connected with the upper end of the sucker rod 11 of column 1 both sides, top rail 4 is fixed on the column 1 by connecting bolt, drive unit 5 is fixed on the top of top rail 4 by connecting bolt, drive unit 5 comprises friction pulley 6, friction pulley 6 is connected with the traction machine of drive unit 5, traction machine is realized the both sides knee-action by friction pulley 6 rotatings, top sheave 7 and lower sheave 8 are installed on the adjustable track of top rail 4, and wire rope pre-tightening apparatus 9 hangs on the wire rope of friction pulley 6 both sides, polished rod eye 2, top sheave 7, lower sheave 8, drive unit 5 and combined counterbalance 10 link up by wire rope.
Opening form is adopted at described top rail 4 two ends, lifting requisite space when satisfying maintenance.
Described wire rope pre-tightening apparatus 9 is made up of pulley and the heavy frame of extension, guarantees that in the oil pumper course of work wire rope is in tensioning state.
