Abstract
An anti-squeezing and anti-biting protection drill rod comprises a pipe body, a male connector and a female connector, wherein the male connector is connected to one end of the pipe body, the female connector is connected to the other end of the pipe body, and at least one end of the pipe body is wrapped by a section of protection sleeve. The protection sleeve is an alloy pipe, and the protection sleeve and the drill rod are made of the same materials. The protection sleeve is tightly connected with the pipe body in a heating assembling mode, or is directly sleeved on the pipe body. Due to the fact that the position, close to the male connector or/and close to the female connector, on the pipe body, is wrapped by the section of the protection sleeve, when the anti-squeezing and anti-biting protection drill rod works, a drilling tool is clamped on the protection sleeve rather than directly make contact with the pipe body, the probability that the drill rod is bit and squeezed by the tool is reduced, the frequency of abnormal shrinkage and fracture of the pipe body of the drill rod can be reduced, the drilling accidents caused by failure of the drill rod is reduced, and the service life of the drill rod is prolonged.
Description
Technical field
The present invention relates to a kind of drilling tool, particularly a kind of anti-squeezing ruined the protection drilling rod that bites.
Background technology
Use in the drilling engineering and consume a large amount of drilling tools, especially the consumption of drilling rod product is huge, except normal wearing and tearing, beyond corrosion consumes, the extruding of on-the-spot tool using and to collide be the key factor that drilling rod damages and consumes, this damage is a large amount of consumption of natural resource not only, priorly also can cause taking place frequently of wellbore construction accident, prevent that the improper damage of drilling rod from being most important technology and management expectancy in drilling rod manufacturing and the use, because drilling tool is the major reason that drilling rod causes undesired damage to the crowded phenomenon of ruining that the chucking in the drilling rod operation process causes, thus prevent drilling rod squeeze that ruining bites and become the drilling rod manufacturing and use in the important topic of research.
Summary of the invention
Purpose of the present invention exactly in order to address the above problem, provides a kind of anti-squeezing to ruin the protection drilling rod that bites.
The object of the present invention is achieved like this: a kind of anti-squeezing ruined the protection drilling rod that bites, and comprises body, is connected the male joint of body one end and the female joint that is connected the body other end, is coated with one section protection tube at least one end of body.
Described protection tube is the compo pipe with drilling rod material of the same type.
Described protection tube is joined with body by hot charging and closely is connected.
Described body is straight tube, and the end forms one section pipeline section that diameter is bigger after connecting protection tube.
Described protection tube is made of continuously the pipeline section of different-diameter, and its external surface has ladder-type structure.
Described protection tube is one section, and this section protection tube is coated on an end that links to each other with male joint and the contiguous male joint of body.
Described protection tube is one section, and this section protection tube is coated on an end that links to each other with female joint and the contiguous female joint of body.
Described protection tube is two sections, wherein one section also contiguous male joint of an end that links to each other with male joint that protection tube is coated on body, and another section protection tube is coated on an end that links to each other with female joint and the contiguous female joint of body.
Compared with prior art, the present invention has the following advantages:
1, one section alloy protective sleeve pipe of configuration can intercept drilling tool and contacts with the direct of body on the drill pipe body, the minimizing drilling rod is bitten by instrument and squeezes the probability of ruining, can reduce the drill pipe body abnormal waste and break, reduce the drilling failure that lost efficacy and cause owing to drilling rod, and improve the application life of drilling rod;
2, protection tube and body are joined with body by hot charging and are combined, and not only have the effect of strengthening drill pipe body, can also reduce the difficulty of end upsetting production technology.
3, protection tube is provided with ladder-type structure, is convenient to power tool and blocks.
Description of drawings
Fig. 1 is the anti-structural representation of ruining the protection drilling rod that bites that squeezes of the present invention.
The specific embodiment
Referring to Fig. 1, anti-squeezing of the present invention ruined the protection drilling rod that bites, and the female joint 3 that comprises body 1, is connected the male joint 2 of body one end and is connected the body other end is coated with one section protection tube 4 at least one end of body.Male joint 2, female joint 3 are weldingly connected with the two ends of body respectively.
Protection tube among the present invention adopts compo pipe or other compo pipe with drilling rod material of the same type.
Protection tube among the present invention is joined with body by hot charging and closely is connected.
Body among the present invention is straight tube, and the end forms one section pipeline section that diameter is bigger after connecting protection tube.
Protection tube among the present invention can be made of continuously the pipeline section of different-diameter, so that its external surface forms ladder-type structure, is convenient to power tool and blocks.
Protection tube can be one section or two sections among the present invention, and when adopting one section, this section protection tube can be coated on an end that links to each other with male joint and the contiguous male joint of body; Or the also contiguous female joint of an end that links to each other with female joint that is coated on body.When adopting two sections, wherein one section also contiguous male joint of an end that links to each other with male joint that protection tube is coated on body, another section protection tube is coated on an end that links to each other with female joint and the contiguous female joint of body.
The present invention is owing to be close to male joint or/and the body of contiguous female joint is coated with one section protection tube, when work, drilling tool is to be clipped on the protection tube, rather than directly contact with body, so just having reduced drilling rod is bitten by instrument and squeezes the probability of ruining, the drill pipe body abnormal waste be can reduce and the drilling failure that minimizing was lost efficacy and caused owing to drilling rod, and the application life of having improved drilling rod broken.
