Abstract
Disclosed is a double-well column-type oil pumping device, which comprises a column fixed on a base. A rope hanger is hung on the two sides of the column, connected with the upper end of a pumping rod, and provided with a pressure sensor. An upper crossbeam is fixed on the column, of which the two sides are respectively provided with an encoder. A drive unit is fixed on the upper crossbeam. A friction wheel is arranged on the drive unit and connected with a tractor of the drive unit. An upper pulley, a lower pulley and a rope tensioner are arranged on an adjustment track of the upper crossbeam. A wire rope pre-tensioner is hung on a wire rope at two sides of the friction wheel. The rope hanger, the upper pulley, the lower pulley, the drive unit, a combined weight and the rope tensioner are connected by the wire rope. The drive unit drives the pumping rod on the two sides of the column in an upper and lower motion. When in maintenance, the adjustment track of the upper crossbeam moves to leave a space for maintenance and hoisting. The maintenance side is hung with the combined weight and the other side is put into operation. The utility model has the advantages of stroke and frequency on-line adjustment, and the other well can normally work when the single well is maintained.
Description
Technical field
The utility model relates to a kind of oil field oil pumper, is specifically related to a kind of twin-well column oil rig.
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 onlinely be adjusted; 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 utility model provides a kind of twin-well column oil rig, and having the stroke jig frequency can online adjustment, and the advantage that another mouthful well still can operate as normal during the individual well maintenance.
In order to achieve the above object, the technical scheme taked of the utility model is:
A kind of twin-well column oil rig, comprise column 1, column 1 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 12 of column 1 both sides, on the polished rod eye 2 pressure sensor is installed, top rail 4 is fixed on the top of column 1, top rail 4 both sides are equipped with encoder, 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, lower sheave 8 and euphroe 11 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, combined counterbalance 10 and euphroe 11 link 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 utility model 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 12 moves up and down, in this process, the polished rod eye 2 of the side that sucker rod 12 load are big drives combined counterbalance 10 by lower sheave 8 and moves up and down, after continuous operation a period of time, transmission data according to drive unit 5 are adjusted combined counterbalance 10, the load-carrying of wire rope pre-tightening apparatus 9, in the individual well maintenance process, utilize the adjustable track of top rail 4 to move top sheave 7, lower sheave 8, euphroe 11, 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 the twin-well column oil rig directly drives by traction machine, and adopt open type structure top rail, can online adjustment 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 utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, a kind of twin-well column oil rig, comprise column 1, column is fixed on the basis with stone bolt, 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 12 of column 1 both sides, on the polished rod eye 2 pressure sensor is installed, the controller that is used to measure the load of sucker rod 12 and the load pressure signal is sent into oil rig, top rail 4 is fixed on the column 1 by connecting bolt, top rail 4 both sides are equipped with encoder, image data in the oil pumper course of work, and the online adjustment of feeding back realization stroke jig frequency by data, 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, lower sheave 8 and euphroe 11 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, euphroe 11 links up by wire rope.
