Abstract
This utility model provides a kind of multi-functional oil well cementing plug, including sleeve pipe and core body；It is characterized in that：Cylinder and dop are provided with described sleeve pipe；Convex strong ring and groove are provided with the core body, the core body top is provided with cavity, and the bottom of the core body is provided with elastic sealing gasket, and the convex strong ring and elastic sealing gasket are in the same size.Some convex rings are provided with the outside of core body, its quantity is, using made by polytetrafluoroethylmaterial material, with resistant to elevated temperatures feature, as its coefficient of friction is extremely low, to become the ideal material of oil well easy to clean more and all；Core body is made up with intensity height of aluminum zinc-magnesium albronze material, the features such as being unlikely to deform, can play and prolong long-life effect, and aluminum alloy materials are light, realize light-weight design.
Description
Technical field
This utility model is related to oil equipment technical field；More particularly, to a kind of multi-functional oil well cementing plug.
Background technology
Oil well, all can be using to plug during probing, and the function of plug is exactly by the cement mortar top in sleeve pipe
Replace down, if no plug, displacement fluid above will result in slurry replacing cement mortar, and the position on plug top to float collar is just
Bruising；After whole cement mortars have been noted, top cement plug is pressed, it is descending that it followed by cement mortar, sticks on internal surface of sleeve pipe for shaving
Cement mortar, and prevent displacement drilling fluid from mixing with cement mortar, it is to avoid afterbody cement mortar pollutes, it is ensured that bottom cementing matter
Amount, when spoiler is reached, shows bruising, then cementing job terminates.Existing traditional plug makes loaded down with trivial details, and uses process
In can not scrape neat cement, and sealing property is bad, is easily caused cement and drilling fluid mixed, affects well cementation effect.
Utility model content
According to the various problems that above-mentioned prior art is present, a kind of multi-functional oil well cementing plug, including sleeve pipe are proposed
And core body；It is characterized in that：Cylinder and dop are provided with described sleeve pipe；Convex ring and groove, institute are provided with the core body
State core body top and be provided with cavity, the bottom of the core body is provided with elastic sealing gasket, and the convex ring and elastic sealing gasket are big
It is little consistent.
Preferably, the core body is made up of aluminum zinc-magnesium albronze material.
Preferably, the convex ring and elastic sealing gasket are made up of polytetrafluoroethylmaterial material.
Preferably, the dop includes dop A and dop B.
The beneficial effects of the utility model are：
According to above-mentioned multi-functional oil well cementing plug, the cylinder of sleeve pipe is inserted into core body first in use
Cavity in, thus the dop on cylinder can be connected with each other with the groove on core body, so sleeve rotating work mistake
Plug will not be caused in journey to come off；When plug play well cementation sealing effectiveness after, you can reverse sleeve pipe, thus can dop with it is recessed
Groove is separated, and the elastic sealing gasket of core body bottom is not in the presence of by sleeve pipe external force, as which has elasticity, can be extensive
Multiple natural spring function, and then oil well is more sealed, is provided with some convex rings on the outside of core body, its quantity it is many and
All it is, using made by polytetrafluoroethylmaterial material, with resistant to elevated temperatures feature, as its coefficient of friction is extremely low, to become easily clear
The ideal material of clean oil well；Core body is made up with intensity height of aluminum zinc-magnesium albronze material, the features such as being unlikely to deform, can be risen
To prolonging long-life effect, and aluminum alloy materials are light, realize light-weight design.
Description of the drawings
Fig. 1 is this utility model planar structure schematic diagram.
Fig. 2 is this utility model dimensional structure diagram.
Specific embodiment
A kind of multi-functional oil well cementing plug according to Fig. 1-Fig. 2, including sleeve pipe 1 and core body 2；Its feature exists
In：Cylinder 8 and dop are provided with described sleeve pipe 1；Convex ring 3 and groove 5,2 top of the core body are provided with the core body 2
Cavity 9 is provided with, the bottom of the core body 2 is provided with elastic sealing gasket 4,4 size one of the convex ring 3 and elastic sealing gasket
Cause.
The core body 2 is made up of aluminum zinc-magnesium albronze material.
The convex ring 3 and elastic sealing gasket 4 are made up of polytetrafluoroethylmaterial material.
The dop includes dop A6 and dop B7.
According to above-mentioned multi-functional oil well cementing plug, the cylinder 8 of sleeve pipe 1 is inserted into core first in use
In the cavity 9 of body 2, thus the dop on cylinder 8 can be connected with each other with the groove 5 on core body 2, so be rotated in sleeve pipe 1
Plug will not be caused during work to come off；After plug plays well cementation sealing effectiveness, you can reverse sleeve pipe, thus can be
Dop is separated with groove 5, and the elastic sealing gasket 4 of 2 bottom of core body is not in the presence of by sleeve pipe external force, due to its tool
It is flexible, natural spring function can be recovered, and then oil well is more sealed, on the outside of core body 2, be provided with some convex rings
3, its quantity is using made by polytetrafluoroethylmaterial material, with resistant to elevated temperatures feature, due to its coefficient of friction more and all
It is extremely low, become the ideal material of oil well easy to clean；Core body 2 be made up of aluminum zinc-magnesium albronze material it is high with intensity, no
Yielding the features such as, can play and prolong long-life effect, and aluminum alloy materials are light, realize light-weight design.
Specific embodiment of the utility model is the foregoing is only, but architectural feature of the present utility model is not limited to this,
Any those skilled in the art in field of the present utility model, all cover of the present utility model by the change or modification made
In the scope of the claims.
