Description
Technical field
This utility model relates to the aid field of oil drilling, is specifically related to manufacture a kind of oil drill rocker abrasionproof protection
The wearing bush body of device.
Background technology
In the exploration and development of oil gas field, protective casing is to bore a string high tensile steel tube opened under before high-pressure oil-gas layer,
After annular space being carried out sealing with cement, reinforcing well can be played, bear intrinsic pressure, isolation cavey formation and high pressure water layer, separate
Different pressure series of strata, to set up normal circulation of drilling fluid, are the installation of well-control equipment, blowout prevention, leakproof and suspension tail simultaneously
Pipe provides reliable guarantee, also has protective effect to production string, has laid good for follow-up drilling well and production testing operation
Basis.
During carrying out wellbore construction in protective casing, its drilling rod rotated is anti-with protective casing inwall helically track
Multiple constantly friction, this not only makes, and tool joint is the most levigate scraps, and more seriously makes the protective casing in many wells direct
Being worn through, make protective casing and well control facility all lose function, once the oil gas of high pressure zone is scurried out, and will appear from more out of control than well head
Even more serious disaster；It addition, skew easily occurs in drilling rod when carrying out production string well cementing operation, when causing operation, bored
Well offset, affect work efficiency.
Utility model content
This utility model provides the wearing bush body of a kind of oil drill rocker abrasionproof protector, with solve because of oil drill rocker with
Directly contact and the problem of worn out sleeve pipe between internal surface of sleeve pipe, it is ensured that drilling well angle, improve drilling efficiency.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is summarized as follows:
A kind of wearing bush body of oil drill rocker abrasionproof protector, in order to be enclosed within oil drill rocker, protection oil drill rocker and
Sleeve pipe is not worn, and described wearing bush body is in the cylindrical shape cut, along anti-on two vertical tangent planes of described wearing bush body
Grinding set body axially arranged connection end, the outer surface of described wearing bush body is uniformly arranged propping up of projection along wearing bush body circumference
Support rib, the length of described support rib is consistent with the length of wearing bush body, and described support rib is parallel to the center of wearing bush body
Axle, the two ends of described wearing bush body are embedded with metallic framework, improve wearing bush body and bear the ability of radial load, strengthen simultaneously
The abrasion-resistance of wearing bush body end face, the inner surface of described wearing bush body is uniformly arranged indent along wearing bush body circumference
Muddy water passage, reduces drilling pressure, improves drilling efficiency.
More excellent, hardness and the intensity of the material of described wearing bush body are below sleeve pipe and oil drill rocker, wear and tear
Time, abrasion will be wearing bush body, without wear sleeve and oil drill rocker.
More excellent, the material of described wearing bush body is urethane rubber materials, increases the use of wearing bush body
Life-span.
More excellent, the internal diameter of described wearing bush body is slightly larger than the external diameter of oil drill rocker, wearing bush body and oil drill rocker
Between relatively rotate, wearing bush body can slide axially on oil drill rocker simultaneously, the external diameter of described wearing bush body
Consistent with the internal diameter of sleeve pipe, support rib protruding on wearing bush body surface contacts with internal surface of sleeve pipe, and protruding support rib stops
Relatively rotating between wearing bush body and sleeve pipe, wearing bush body can slide up and down at internal surface of sleeve pipe, reduces frictionally damage.
Beneficial effect produced by this utility model:
1, effectively prevent oil drill rocker to contact with the direct of internal surface of sleeve pipe, thus avoid sleeve pipe and ground by oil drill rocker
Wear；
Moment of torsion when 2, effectively reducing lower brill frictional resistance and creep into, also acts the effect of protection drilling rod；
3, drilling well angle can be corrected in time, be effectively increased drilling efficiency；
4, material consumption is few, reduces drilling cost.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
In figure label be respectively as follows: 1, metallic framework；2, muddy water passage；3, support rib；4, end is connected.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.Reality of the present utility model
The mode of executing includes but not limited to the following example.
Embodiment 1
As it is shown in figure 1, the wearing bush body of a kind of oil drill rocker abrasionproof protector, in order to be enclosed within oil drill rocker, protection
Oil drill rocker and sleeve pipe are not worn, and described wearing bush body is in the cylindrical shape cut, and two of described wearing bush body erect
Along wearing bush body axially arranged connection end 4 on tangent plane, the outer surface of described wearing bush body is along wearing bush body circumference uniformly
Arranging the support rib 3 of projection, the length of described support rib 3 is consistent with the length of wearing bush body, and described support rib 3 is parallel to prevent
The central shaft of grinding set body, the two ends of described wearing bush body are embedded with metallic framework 1, and the inner surface of described wearing bush body is along anti-
Grinding set body circumference is uniformly arranged the muddy water passage 2 of indent.
The step being arranged on oil drill rocker by abrasionproof protector is: breaks wearing bush body into two with one's hands, is enclosed within by wearing bush body
On oil drill rocker, close up wearing bush body, by connecting end 4, wearing bush body is fixed.
In the present embodiment, wearing bush body is fixed on inside pipe casing, between support rib 3 by being disposed to of support rib 3
Groove also circulation for muddy water between wearing bush body and sleeve pipe provide convenience, it is to avoid the muddy water friction to sleeve pipe, subtract
Few drilling pressure；The setting of metallic framework 1 improves wearing bush body and bears the ability of radial load, enhances wearing bush simultaneously
