Abstract
The pumping unit can used for shafts with obliquity of 0-45 deg. In the said pumping unit, one side leg of herringbone bridging is hinged to base seat and the other side leg is connected to arched plate on base seat. The arched plate has several rows of radial conciliation holes, and its upper connecting rod is divided into two inserted sections for length regulation, and the crank has two rows of radial holes for stroke regulation and crank offset angle regulation. In the said pumping unit, between the horse head and balance beam a truss structure is formed to reduce the weight of horse head.
Description
The present invention relates to a kind of pumping unit of field produces well, belong to pumping unit for inclined and vertical shaft.
The field produces well is to beat straight well on the spot on ground according to oilbearing stratum, and most producing wells all are peupendicular holes, make things convenient for underground work.Owing to reasons such as surface structureses, can not beat (brill) peupendicular hole on the spot, in order to extract the crude oil of this place's oilbearing stratum out, and beat oblique straight well, tiltedly general 0-45 degree that tilt of straight well in the strange land.At present, pumping unit on the oblique straight well well head, it is to design according to the angle of inclination of oblique straight well, and promptly the angle of inclination of this pumping unit adaptation slant well is fixed, and it is just incompatible to have gone beyond the scope, need otherwise designed, present pumping unit for inclined and vertical shaft can not adapt in 0-45 degree scopes to be regulated, and accommodation is little, needs to increase the kind of pumping unit undoubtedly, increase investment, and bring inconvenience to production management.
The objective of the invention is to overcome the shortcoming in the above-mentioned present technology, change adjustable pumping unit for inclined and vertical shaft at the oblique straight well of 0-45 degree and provide a kind of.
Purpose of the present invention can reach by the following technical programs: have crank and the connecting rod that motor drives through gearbox, propping up the herringbone that inclination is arranged on the pedestal, propping up on the support has horse head, walking beam on the horse head and rod hinge connection; The present invention makes the lower end of above-mentioned support one side leg and pedestal hinged with bearing pin, and the lower end of side leg is connected on the adjustment arc plate on the pedestal with bolt in addition; This arc plate is to be on the endless belt in the center of circle with the hinging pin shaft, is drilled with the above radial hole of 2 rows on the arc plate; Connecting rod is used bolt after being divided into two sections grafting, and the connecting rod upper edge shaft axis of crank side has 2 groups of above holes of adjusting; Having with the crank rotatingshaft on crank and the side arm that connecting rod is connected is the radial hole in the center of circle; Horse head adopts between horse head shell and the walking beam and is connected with truss.
Be drilled with on the above-mentioned arc plate with by hinging pin shaft be horizontal line (face) between angle be 0,16,26 and 36 the degree 4 row radial holes, can be center line with the radial line of every row's radial hole, be drilled with in the outside of every center line 1 row parallel hole; Can there be equally distributed 4 groups to reconcile the hole; The shaft axis angle of 2 row's radial holes and crank is 8 degree and 27 degree on the crank.Wherein radial hole designs according to the inclined shaft excursion on the arc plate, and the well of different gradients is connected with corresponding radial hole row, and outer round is to be connected in high angle hole; Connecting rod is pegged graft and can be made it that stretchability is arranged, to satisfy the changes in pitch needs of inclined shaft; 2 row's radial holes can reach purpose of design according to the offset angle design by above-mentioned design on the crank.
The present invention compares with above-mentioned prior art and has following effect: one of this pumping unit for inclined and vertical shaft can adapt to the oblique straight well production requirement that 0-45 degree change, and stable performance, saves investment, and convenient production gone up management.
Accompanying drawing 1 is a diagrammatic sketch of the present invention;
Accompanying drawing the 2, the 3rd, counterweight (15) diagrammatic sketch that crank on Fig. 1 (7) is different with connection;
Accompanying drawing 4 is connecting rod on Fig. 1 (6) diagrammatic sketch.
Below in conjunction with accompanying drawing will the present invention will be further described;
Have crank (7,8) and the connecting rod (6) that motor (12) drives through gearbox (10), pedestal (14) is gone up the herringbone (5) that (seat) has inclination, support (5) is gone up (hinged) horse head (1), the walking beam (22) on the horse head (1) and connecting rod (6), the hinged formation four link type of support (5) pumping unit for inclined and vertical shaft.This pumping unit for inclined and vertical shaft is by shown in the accompanying drawing 1, the lower end of support (5) one side legs (20) and ground top base (14) are hinged with bearing pin (16), make support (5) rotation be arranged around bearing pin (16), the lower end of the opposite side leg (19) of support (5) is connected on the adjustment arc plate (9) on the pedestal (14) with bolt, arc plate be vertical plate be connected in the gearbox on pedestal and the pedestal support (11) on, form integral body with pedestal, it is to be on the endless belt in the center of circle with bearing pin (16), is drilled with 2 row's above radial holes (17) on the arc plate (9).Connecting rod (6) is used bolt after being divided into two sections grafting, makes it become flexible rod; Connecting rod (6) upper edge shaft axis is drilled with 2 groups of above holes (18) of reconciling, to satisfy the requirement that horse head (1) swings up and down.Having with the crank rotatingshaft on crank (7) and the side arm that connecting rod (6) is connected is 2 row's radial holes (21) in the center of circle, in order to reconcile the offset angle on the crank.Horse head 1 constitutes by being connected with truss between horse head shell and the walking beam (22), can alleviate the weight of horse head.
Can bore 4 row's radial holes (17) on the above-mentioned arc plate (9), every row's radial hole be by bearing pin (16) horizontal line (face) between angle be 0,16,26 and 36 to spend; Radial line that can every row's radial hole is a center line, is drilled with 1 group of parallel hole (17) in the outside of every center line, in order to firm connection of the leg (19) of support (5).There are 4 groups of non-uniform Distribution to reconcile hole (18) on the connecting rod (6), can satisfy the conciliation needs of length of connecting rod.2 row's radial holes (21) are 8 degree and 27 degree with the shaft axis angle of crank (7), in order to reconcile the offset angle on the crank.
At present oblique straight well is generally in 0-45 degree scopes; Arc plate (9) is gone up a few row's radial holes, goes up the conciliation of leg (19) in order to different gradient wells and support (5) and installs, to satisfy the needs that inclined shaft is produced.Connecting rod (6) is pegged graft, and is to adopt to be a double-deck bar, is inserted by another section single pole, and the needs of conciliation can be satisfied in the last 4 groups of holes of this section (18), and it is reciprocating to make oil pumping polish rod on the well head (2) aim at well head.In addition, platform (3) is arranged on the support (5), double joint connecting rod (6) is hinged with axle (4) and walking beam, and motor (12) is subjected to the control of power controling box (13).
