Description

Double well interactive beam-rope pulley autobalanced oil pumping unit
The present invention relates to a kind of oil pumper that is used for oil field cluster well exploitation, particularly a kind of double well interactive beam-rope pulley autobalanced oil pumping unit.
Oil well crude oil lifting equipment in the past all adopts the configuration of a well one machine, has not only employed a large amount of technical equipments, and has expended a large amount of energy, has increased cost for oil production, has reduced economic benefit.
The object of the present invention is to provide a kind of double well interactive beam-rope pulley autobalanced oil pumping unit that is used for the platform cluster well, it utilizes a cover oil production equipment that adjacent two mouthfuls of wells are recovered the oil simultaneously, when a bite oil well wherein need stop production when carrying out workover treatment, also allow another mouthful well is carried out ordinary production, reduced capital investment and management of equipment maintenance expense; Make full use of plant capacity, improved system mechanics efficient, energy-saving and cost-reducing, reduce cost for oil production, increase economic efficiency.
The object of the present invention is achieved like this; it is by switch board (1); motor (2); brake (3); reducer (4); reel (5); directive wheel (6); rope (7); balance weight (8); walking beam (9); frame (10); sucker rod (11); horse head (12); connector (13); overload protection arrangement (14); commutator (15); stop (16) and base (17) parts are formed; on base (17); switch board (1) and motor (2); brake (3); reducer (4); reel (5) connects successively; rope (7) is connected with walking beam (9) afterbody through directive wheel (6) by reel (5); the front portion of walking beam (9) also uses rope (7) and directive wheel (6) to link together; walking beam (9) afterbody is equipped with balance weight (8); horse head (12) is equipped with in the front portion; be that frame (10) supports in the middle of the walking beam (9); be connected to connector (13) on the horse head (12) successively; overload protection arrangement (14) and sucker rod (11), commutator (15); the frame (10) that is contained in stop (16) goes up and is connected with electric machine control system.
During work, reversing motor drives reel by reducer and rotates, rope drives the afterbody of two mouthfuls of well walking beams through directive wheel by reel, the front portion of walking beam also links together with rope and directive wheel, realize that two mouthfuls of well sucker rods pump, and situation that can not be descending because of factors such as resistances can prevent the sucker rod down stroke time takes place.Balance weight is placed on the afterbody of walking beam, and the braking principle of brake adopts braking open in usual, mainly plays the protection system safe functioning, and when promptly shutdown of pumping machine or system broke down, the braking driving wheel avoided balance weight, sucker rod to move up and down.
The present invention is owing to adopted reversing motor to drive the reel rotation by reducer, rope drives the afterbody of two mouthfuls of well walking beams through directive wheel by reel, the front portion of walking beam also links together with rope and directive wheel, realize that two mouthfuls of well sucker rods pump, and situation that can not be descending because of factors such as resistances can prevent the sucker rod down stroke time takes place, realized the design of a soft transmission of driving-belt and a machine twin-well, and the front and rear part of walking beam linked together respectively, help the normal operation of two mouthfuls of wells, machine extraction oil pole to the viscous crude cluster well is favourable, this invention has greatly improved system mechanics efficient, has reduced capital investment, energy consumption and management and maintenance expense can be increased economic efficiency significantly, and it is easily manufactured, safe and reliable, being easy to adjust running parameter, operating simple and easyly, is a kind of high-efficiency and energy-saving type oil production equipment.
Accompanying drawing is the double well interactive beam-rope pulley autobalanced oil pumping unit structural representation.
Below in conjunction with accompanying drawing working of an invention is described further.
As shown in the figure, the present invention is made up of switch board 1, motor 2, brake 3, reducer 4, reel 5, directive wheel 6, rope 7 (LJZ high strength cord, wire rope, chain, broadband, row's rope, V-belt, nonwoven etc.), balance weight 8, walking beam 9, frame 10, sucker rod 11, horse head 12, connector 13, overload protection arrangement 14, commutator 15, stop 16 and base 17.Wherein, reel 5 and directive wheel 6 types adapt with corresponding rope 7 types, rope 7 has adopted LJZ high strength cord, wire rope, chain, broadband, row's rope, V-belt, nonwoven etc., balance weight is placed on the afterbody of walking beam, adopt the power unit of speed governing reversing motor and reducer combination to drive reel, can satisfy the variation requirement of oil pumper, guarantee that oil pumper carries out oil well production by given running parameter stroke and jig frequency.
The braking principle of brake 3 adopts braking open in usual, mainly plays the protection system safe functioning, and when promptly shutdown of pumping machine or system broke down, the braking driving wheel avoided balance weight, sucker rod to move up and down.
Commutator 15 is controllers of buncher 2 rotatings commutation, promptly controls oil pumper stroke and jig frequency.Stop 16 then is a kind of safety device, in order to prevent that balance weight is offside and the accident that causes.The adjustment of stroke, jig frequency is mainly set by the control panel of switch board 1, and is as long as the corresponding data of input get final product step-less adjustment, convenient and reliable during adjustment.
Counterweight of the present invention mainly contains dual mode: the one, and utilize the difference of two mouthfuls of aboveground down stroke suspending point loadings to carry out balance.Be the balance weight of the down stroke suspending point loading of a bite well for the aboveground stroke of another mouthful.The 2nd, if the down stroke suspending point loading of a bite well can not satisfy the counterweight requirement of another mouthful well, or individual well then can adopt the counterweight balance when producing.Ordinary circumstance is to adopt the former earlier, re-uses the latter.
