Description
Technical field
The present invention relates to petroleum gas and Coal-seam Gas Recovery Technologies, especially efficient eccentric wear prevention pumping rod guide and answer
Use method.
Background technique
When coal-bed gas exploitation, in the well using screw pump, sucker rod is used to transmit torque to reduce investment.Drilling well
According to wellbore construction design requirement in journey, the smooth middle target of directional well is realized, it is necessary in kickoff point (KOP) to the mistake between hold angle point
Degree well section meets design requirement by constantly rectifying a deviation, thus the rate of over-all angle change (both: dog-leg severity) of the well section show compared with
Significantly fluctuate.Sucker rod rotates other than bearing torque in angle buildup interval, still suffers from very big moment of flexure, takes out in the position
Beam hanger every revolution will distort overturning once, bear very big alternating load, itself be also subjected to very big pulling force and torque, at this moment
It just needs to be connected with guider, existing guider rotational resistance is larger, increases power consumption, and generate well oil pipe larger
Abrasion, shortens the service life of oil pipe.
Summary of the invention
The object of the present invention is to provide a kind of efficient eccentric wear prevention pumping rod guide that can extend oil pipe service life, it gram
The shortcomings that having taken the prior art, the object of the present invention is achieved like this, it includes sucker rod lower contact, ball head universal, helps
Positive device, universal joint connectiing shaft head, bulb shell, sucker rod top connection, the universal joint connectiing shaft head are placed in ball head universal
It is intracavitary in bulb, according to the linear contact that the bulb centre of sphere radiates, it is configured to quadrangle chamfering；The structure is also possible to convenient add
The hexagon of work or other polygons；The universal joint connectiing shaft head and ball head universal are placed in bulb shell, wherein ten thousand
It is fixed as one to section connectiing shaft head with bulb shell；The centralizer is placed in the outside of ball head universal；The pumping
Beam hanger lower contact, sucker rod top connection are connect with one end of ball head universal respectively, while being connect in sucker rod lower contact, sucker rod
The other end of head is connect with sucker rod respectively.
Ball head universal can be swung in bulb shell around the centre of sphere, and swing angle is up to 4 degree, and two bulbs are universal
It is 8 degree that section, which forms angle,.
The centralizer outer diameter is greater than bulb shell and other part outer diameters, centralizer periphery have been provided with spiral shell
Spin slot, helicla flute can be such that centralizer contacts uniformly with pit shaft oil pipe, and increase fluid passage section product；Ball head universal can helped
It is rotated in the hole of positive device.
Application method of the invention: sucker rod lower contact, sucker rod top connection are respectively connect with sucker rod first；It takes out
Beam hanger has been respectively subjected to pulling force or pressure in the different location of pit shaft, and ball head universal is placed in bulb shell, uses bulb joint
Pulling force or pressure can be born, in inclination section, it, which be can produce, curves, since spherical structure makes its stress point always in the centre of sphere,
It does not influence pulling force or pressure transmitting after deflection angle；Centralizer can promote efficient eccentric wear prevention pumping rod guide in inclination section
Position contacts centralizer with pit shaft tube inner wall, rather than the efficiently other parts and oil pipe of eccentric wear prevention pumping rod guide
Inner wall contact, cleverly avoids the abrasion of energy loss and tube inner wall.
Meaning of the present invention is: the present apparatus is adapted to the position of directional well inclination section, due in centralizer and pit shaft oil pipe
Wall contact, rather than efficiently other parts of eccentric wear prevention pumping rod guide are contacted with tube inner wall, cleverly avoid energy
The abrasion of loss and tube inner wall.Ball head universal is placed in bulb shell, since spherical structure makes its stress point exist always
The centre of sphere, bears pulling force or pressure with bulb joint, does not influence pulling force or pressure transmitting after deflection angle；In short, this dress
It sets and extends the tired time of sucker rod in use, dissolved sucker rod and broken because of Moment de-, extended operation
Period.

Specific embodiment
Embodiment 1, the present invention include sucker rod lower contact 1, ball head universal 2, centralizer 3, universal joint connectiing shaft head 4,
Bulb shell 5, sucker rod top connection 6, the universal joint connectiing shaft head 4 be placed in it is intracavitary in the bulb of ball head universal 2, according to ball
The linear contact that the heart of head shooting radiates, is configured to quadrangle chamfering；The structure is also possible to facilitate the hexagon of processing or other
Polygon；The universal joint connectiing shaft head 4 is placed in bulb shell 5 with ball head universal 2, wherein universal joint connectiing shaft head 4
It is fixed as one with bulb shell 5.The centralizer 3 is placed in the outside of ball head universal 2；The sucker rod lower contact
1, sucker rod top connection 6 is connect with one end of ball head universal 2 respectively, while sucker rod lower contact 1, sucker rod top connection 6
The other end is connect with sucker rod respectively.
Embodiment 2, ball head universal 2 can be swung in bulb shell 5 around the centre of sphere, and swing angle is up to 4 degree, and two
It is 8 degree that a ball head universal 2, which forms angle, this is the gradient according to drilling well and designs.
Embodiment 3,3 outer diameter of the centralizer are greater than bulb shell 5 and other part outer diameters, outside centralizer 3
Helicla flute it has been provided with week, helicla flute can be such that centralizer 3 contacts uniformly with pit shaft oil pipe, and increase fluid passage section product；Ball
Head gimbal 2 can rotate in the hole of centralizer 3.
Embodiment 4, the universal joint connectiing shaft head 4 are placed in intracavitary in the bulb of ball head universal 2, put according to the bulb centre of sphere
The linear contact penetrated is configured to quadrangle chamfering or hexagon and other polygons.Such structure guarantees that universal joint connects
Spindle head 4 and ball head universal 2 only transmit torque function at work, are not subject to other strength.The structure in practical most often
What is seen is allen wrench, and all design has a head of six sides with gradient structure, reality mostly at the long end of allen wrench
Purposes be exactly including six side's screws since the factors such as spatial position, allen wrench center line can be with interior six sides screw center lines
The elastic of screw is realized in rotation at an angle.
Embodiment 5, application method of the invention: first by sucker rod lower contact 1, sucker rod top connection 6 respectively with pumping
Beam hanger connection；Sucker rod has been respectively subjected to pulling force or pressure in the different location of pit shaft, and ball head universal 2 is placed in bulb shell 5
It is interior, pulling force or pressure can be born with bulb joint, it, which can produce, in inclination section curves, in tie point without generating other answer
Power does not influence pulling force or pressure transmitting since spherical structure makes its stress point always in the centre of sphere after deflection angle；Righting
Device 3 can promote efficient eccentric wear prevention pumping rod guide in deflecting fragment position, contact centralizer 3 with pit shaft tube inner wall, without
It is that other parts of efficient eccentric wear prevention pumping rod guide are contacted with tube inner wall, cleverly avoids in energy loss and oil pipe
The abrasion of wall.
