Abstract

The utility model relates to an anti-attrition sleeve for an old drill rod connector. According to the technical scheme, the anti-attrition sleeve for the old drill rod connector comprises an old drill rod and is characterized in that a cylindrical steel anti-attrition sleeve is connected with a pliers area surface of an inner thread adapter at the upper end of the old drill rod; a cylindrical steel anti-attrition sleeve is also connected with a pliers area surface of an outer thread adapter at the lower end of the old drill rod; a welding point is arranged at the lower end of the pliers area surface of the inner thread adapter; welding points are respectively arranged at two ends of the pliers area surface of the outer thread adapter; and through holes are formed in the cylindrical steel anti-attrition sleeves. Compared with the prior art, the anti-attrition sleeve for the old drill rod connector has the advantages of simple structure, convenience in connecting, low cost, capabilities of increasing the torque of the drill rod connector and preventing swelling buckle, and long service life. The anti-attrition sleeve is easily exchanged and conveniently operated, is high in reuse ratio, and is conveniently and widely applied to the petroleum, natural gas drilling and non-excavation fields.

Description

A kind of old tool joint anti-attrition cover
One, technical field
The utility model relates to the old drilling rod that a kind of oil, gas drilling and non-excavation use, and is a kind of old tool joint anti-attrition cover concretely.
Two, background technology
At present, at oil, gas drilling, especially in the non-excavating construction process; Drilling rod is as main drilling tool articles for use, in use in the face of the grinding of stratum such as underground silt and goose soft rock to tool joint, in the short period of time; Tool joint reduced diameter, parameters such as the moment of torsion that bears, pulling force all reduce greatly, have seriously influenced old drilling life of drill pipe; It is higher relatively to change the joint cost, weld wear-resisting band at joint and be not easy to non-excavating construction, and cost is higher.
Three, utility model content
The purpose of the utility model is exactly the defective that exists to prior art, and a kind of simple in structure, old tool joint anti-attrition cover that recycling rate of waterused is high is provided.
Its technical scheme is: comprise old drilling rod; It is characterized in that: the surface, pincers district of old drilling rod upper end female adapter is connected with cylindric steel anti-attrition cover; The surface, pincers district of old drilling rod lower end male connection also is connected with cylindric steel anti-attrition cover; The lower end on the surface, pincers district of female adapter is provided with pad, and the two ends on the surface, pincers district of male connection are respectively equipped with pad and pad, and described cylindric steel anti-attrition puts and is provided with through hole.
The utility model compared with prior art; Have simple in structure, easy to connect, with low cost, improve the tool joint moment of torsion, the advantage of prevent to rise button, long service life; And be easy to replacing, simple operation, recycling rate of waterused height, be convenient in oil, gas drilling and the field extensive use of non-excavation.
Four, description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Five, the specific embodiment
As shown in the figure; Comprise old drilling rod 1; The surface, pincers district 4 of old drilling rod 1 upper end female adapter 2 is connected with cylindric steel anti-attrition cover 6; The surface, pincers district 7 of old drilling rod 1 lower end male connection 3 also is connected with cylindric steel anti-attrition cover 9, and the lower end on the surface, pincers district 4 of female adapter 2 is provided with pad 10, and the two ends on the surface, pincers district 7 of male connection 3 are respectively equipped with pad 11 and pad 12; Described cylindric steel anti-attrition cover 6 is provided with through hole 5, and described cylindric steel anti-attrition cover 9 is provided with through hole 8.
After old drilling rod uses; Old drilling rod 1 upper end female adapter, 2 pincers district clamps the wearing and tearing that surface, district 7 all exists to a certain degree with lower end male connection 3 in surface 4; During operation; At first turning processing is carried out on surface 4, female adapter 2 pincers district and surperficial 7 surfaces, male connection 3 pincers districts, gone to clamp the tong catcher mark on surface, district 4 and surface, pincers district 7, and make itself and anti-attrition cover 6 and anti-attrition cover 9 interior hole dimensions reach interference fit; After anti-attrition cover 6 and anti-attrition cover 9 be assembled to surface, pincers district 4 and surface, pincers district 7 respectively; Through hole on the anti-attrition cover 65 and through hole 8 on the anti-attrition cover 9 are welded, simultaneously the pad 10 of surperficial 4 lower ends, pincers district of female adapter 2 and the pad 11 at surperficial 7 two ends, male connection 3 pincers districts are welded with pad 12, thereby realized that old drilling rod 1 continues to come into operation.
