Abstract
The utility model discloses a clamp of oil drill pipe abrasionproof protector for the home range of restriction anti -abrasion sleeve body, two common clamps are used together, and two clamps are fixed respectively on the oil drill pipe at anti -abrasion sleeve body both ends, adopt the forging and pressing aluminum alloy to make, including convex clamp lamella, articulated piece, convex clamp lamella has two at least, convex clamp lamella between articulated through articulated piece, wherein edge clamp axial evenly sets up the screw hole on the perpendicular tangent plane of a convex clamp lamella, the relevant position on the perpendicular tangent plane of another convex clamp lamella sets up the connecting screw.
Description
Technical field
The utility model relates to the aid field of oil drilling, is specifically related to manufacture a kind of oil drill rocker abrasionproof protection
The clip 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 internal 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 operating efficiency.
Utility model content
The utility model provides the clip of a kind of oil drill rocker abrasionproof protector, in order to coordinate fixing wearing bush body,
Solve because directly contacting and the problem of worn out sleeve pipe between oil drill rocker with internal surface of sleeve pipe, it is ensured that drilling well angle, improve drilling well effect
Rate.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is summarized as follows:
The clip of a kind of oil drill rocker abrasionproof protector, for limiting the scope of activities of wearing bush body, usual two cards
Hoop is used together, and two clips are separately fixed on the oil drill rocker at wearing bush body two ends, uses forging and stamping aluminium alloy to make, tool
There are high intensity and high anti-corrosion capability, including circular arc clip lobe, pin-joint piece, described circular arc clip lobe at least two pieces, institute
State between circular arc clip lobe hinged by pin-joint piece, along card on the vertical tangent plane of a piece in two pieces of circular arc clip lobes at two ends
Hoop is axially uniformly arranged screwed hole, and the relevant position on the vertical tangent plane of another block arranges attachment screw, during installation, by attachment screw
Screw in screwed hole so that circular arc clip lobe constitutes cylinder circle；Arc-shaped clamp lobe inner surface arranges rubber blanket, it is to avoid clip
Very stiff and demanding with oil drill rocker contact, thus avoid the clip infringement to oil drill rocker itself.
More excellent, described attachment screw is provided with stop washer, with guarantee clip will not loosen on oil drill rocker and
Fall well, it is ensured that downhole safety.
More excellent, the external diameter of described clip is less than the external diameter of wearing bush body, it is to avoid clip directly contacts with internal surface of sleeve pipe
And wear sleeve.
Beneficial effect produced by the utility model:
1, ensure that wearing bush body is the most movable；
2, directly do not contact with sleeve pipe, reduce friction loss；
3, 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 Facad structure schematic diagram of the present utility model；
Fig. 2 is structure schematic diagram of the present utility model；
In figure label be respectively as follows: 1, screwed hole；2, attachment screw；3, circular arc clip lobe；4, stop washer；5, hinged
Sheet.
Detailed description of the invention
With detailed description of the invention, the 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 clip of a kind of oil drill rocker abrasionproof protector, for limiting the scope of activities of wearing bush body,
Usual two clips are used together, and two clips are separately fixed on the oil drill rocker at wearing bush body two ends, use forging and stamping aluminium
Alloy is made, low price and have high intensity and high anti-corrosion capability, including circular arc clip lobe 3, pin-joint piece 5, described circle
Arc-shaped clamp lobe 3 at least two pieces, hinged by pin-joint piece 5 between described circular arc clip lobe 3, two pieces of circular arcs at two ends
Axially it is uniformly arranged screwed hole 1, the relevant position on the vertical tangent plane of another block along clip on the vertical tangent plane of a piece in clip lobe 3
Attachment screw 2 is set, during installation, attachment screw 2 is screwed in screwed hole 1 so that circular arc clip lobe 3 constitutes cylinder；Circle
Arc-shaped clamp lobe 3 inner surface arranges rubber blanket, it is to avoid clip is very stiff and demanding with oil drill rocker to be contacted, thus avoids clip itself to stone
The infringement of oil drilling rod.
During installation, hoop sleeve is connected on oil drill rocker, finally attachment screw 2 is all screwed in screwed hole 1, thus will card
Hoop is fixed on oil drill rocker, and the cushioning effect of rubber blanket makes not occur between clip and oil drill rocker relative motion.
The present embodiment simple in construction, reasonable in design, it is easy to accomplish, practicality is relatively strong, wearing bush body can be effectively ensured and exist
Activity in certain limit.
Embodiment 2
Make to optimize further on the basis of the clip of a kind of oil drill rocker abrasionproof protector described in embodiment 1, described
Stop washer 4 it is provided with, to guarantee that clip will not loosen on oil drill rocker and fall well, it is ensured that downhole safety on attachment screw 2.
Embodiment 3
Make to optimize further on the basis of the clip of a kind of oil drill rocker abrasionproof protector described in embodiment 1 or 2, institute
State the external diameter external diameter less than wearing bush body of clip, it is to avoid clip directly contacts and wear sleeve with internal surface of sleeve pipe.
It is embodiment of the present utility model as mentioned above.The utility model is not limited to above-mentioned embodiment, anyone
Should learn the structure change made under enlightenment of the present utility model, every have same or like skill with the utility model
Art scheme, within each falling within protection domain of the present utility model.
