Description
Technical field
The present invention relates to the sucker rods for having bar oil recovery directional horizontal wellss, heavy oil wells, thermal recovery technology, belong to a kind of sucker rod
The new design of column, particularly a kind of isometrical hollow pipe roofbolt of eccentric abrasion prevention.
Background technology
There is the common rod string feature of bar producing well：
（1）8-10 meters of body of rod length is solid construction, and the upset head of double headed roller, upset head diameter is twice of shank diameter or so.
（2）It is connected between the body of rod by double female box cuplings, double mother's box cupling diameters are twice or so of shank diameters.Length is generally
100-150mm。
（3）More common sucker rods after double female box cupling connections, form the rod string with multiple steps.Total
In long range, these steps form laciniation.In oil pumping process, the step between oil pipe constantly collides, high failure rate.
（4）Abrasion loss is accumulated at step, and break-off accident easily occurs, and shortens the working life of whole roofbolt.
Invention content
The purpose of the present invention is to provide a kind of isometrical hollow pipe roofbolt of eccentric abrasion prevention, rational in infrastructure, dependable performance is being adopted
Can be on the basis of Job Operations flow not be changed during oil, hollow pipe roofbolt connects with tube inner wall in length range interior lines
It touches, avoids the abrasion at common rod string step, greatly improve the service life of oil pipe and rod string.
The object of the present invention is achieved like this：A kind of isometrical hollow pipe roofbolt of eccentric abrasion prevention has hickey by both ends
Isometrical hollow pipe and both ends have threaded double pin ends and be composed, hollow length of tube is 5-10 meters, double pin end overall lengths
Degree is less than 400mm, and roofbolt total length is more than 150 meters after combination, and the outer diameter of hollow pipe is greater than or equal to the outer diameter of double pin ends.It is double
Elevator suspension section is designed on pin end and double pin ends tighten flat.
The operation principle of the present invention：
1, isometrical hollow pipe outside diameter is more than or equal to double pin end outer diameters, is threadedly coupled；
2, isometrical hollow length of tube is 5-10 meters, and double pin end length are less than 400mm, after ensureing whole roofbolt connection in this way, outside
Diameter is consistent.
3, in oil recovery process, isometrical hollow pipe roofbolt is contacted with oil pipe column wall in global extent, increases connect in this way
Contacting surface is accumulated, and avoids zigzag unstable wear phenomenon.
Meanwhile during lifting machinery hanging, elevator is clamped on double pin ends, convenient working.
Rational in infrastructure, dependable performance of the invention, realizing can be on the basis for not changing work flow in oil recovery process
On, isometrical hollow pipe roofbolt is contacted with tube inner wall in length range interior lines, avoids the abrasion at common rod string step, greatly
Width improves the service life of oil pipe and rod string.And in lifting operation, elevator is clamped on double pin ends, facilitates work
Industry.
Description of the drawings
Below in conjunction with attached drawing, the invention will be further described, schematic cross-sectional views of the Fig. 1 for the present invention, Fig. 2
Enlarged structure schematic diagram for double pin ends.
Specific embodiment
A kind of isometrical hollow pipe roofbolt of eccentric abrasion prevention as shown in Figure 1 and Figure 2, has the isometrical hollow of hickey 5 by both ends

400mm, roofbolt total length is more than 150 meters after combination, and the outer diameter of hollow pipe 1 is greater than or equal to the outer diameter of double pin ends 2.Double public access
Elevator suspension section 4 is designed on first 2 and double pin ends tighten flat 6.The outer diameter of hollow pipe 1 for 38.1 or 41.28 or 46 or
55.6㎜.Hollow pipe is set to tighten flat 3 on the cylindrical surface of 5 inside hollow pipe 1 of interface.Elevator suspension section 4 is undergauge
Cylinder, a diameter of 19-30 ㎜ of cylinder, the length of cylinder is 80-150 ㎜.At the both ends of elevator suspension section 4, transition circle is set
Arc angle, transition circle arc angle are to be connected to external arc 8 by the Inner arc 7 of connection undergauge cylinder, and external arc 8 is connected to double pin ends 2
External cylindrical surface, wherein 7 radius of Inner arc is 40-90 ㎜, and the radius of external arc 8 is 5-20 ㎜.
