Abstract
The invention provides an anti-collapsing and anti-striking protection drilling rod. The anti-collapsing and anti-striking protection drilling rod comprises a pipe body, a male connector connected with one end of the pipe body, and a female connector connected with the other end of the pipe body, wherein at least one end of the pipe body is coated with a section of protection sleeve. The protection sleeve is an alloy pipe which is made of the same type of materials of the drilling rod and is tightly connected with the pipe body through hot assembly or directly sleeves the pipe body. According to the anti-collapsing and anti-striking protection drilling rod, the pipe body which is close to the male connector and/or the female connector is covered with one section of the protection sleeve so that a well drilling tool is clamped on the protection sleeve and is not directly in contact with the pipe body, and furthermore, the possibility of striking and collapsing the drilling rod by the tool is reduced; the abnormal loss and crack of the pipe body of the drilling rod can be reduced; a well drilling accident caused by that the drilling rod loses efficacy is reduced; the service life of the drilling 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
In drilling engineering, use 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 use instrument and to collide be a key factor of drill pipe wear and consumption, 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 manufacture and use procedure, the crowded phenomenon of ruining clamping in drilling rod operation process being caused due to drilling tool is the major reason that drilling rod causes undesired damage, so prevent drilling rod squeeze that ruining bites and become drilling rod manufacture and use in the important topic of research.
Summary of the invention
Object 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 the female joint that comprises body, is connected to the male joint of body one end and is connected to the body other end, is coated with one section of 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 and is closely connected by hot charging.
Described body is straight tube, and end connects after protection tube, forms one section of pipeline section that diameter is larger.
Described protection tube consists 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 of protection tube is coated on the one end being connected with male joint the contiguous male joint of body.
Described protection tube is one section, and this section of protection tube is coated on the one end being connected with female joint the contiguous female joint of body.
Described protection tube is two sections, wherein one section of also contiguous male joint in the one end being connected with male joint that protection tube is coated on body, and another section of protection tube is coated on the one end being connected with female joint the contiguous female joint of body.
Compared with prior art, the present invention has the following advantages:
1, on drill pipe body, configuring one section of alloy protective sleeve pipe can intercept drilling tool and contact with the direct of body, reducing drilling rod is bitten and squeezes the probability of ruining by instrument, can reduce drill pipe body abnormal waste and break, the drilling failure that minimizing was lost efficacy and caused due to drilling rod, and the application life of improving drilling rod;
2, protection tube and body are joined with body and are combined by hot charging, 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.
Accompanying drawing explanation
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 to the male joint 2 of body one end and is connected to the body other end, is coated with one section of 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 in the present invention adopts compo pipe or other compo pipe with drilling rod material of the same type.
Protection tube in the present invention is joined with body and is closely connected by hot charging.
Body in the present invention is straight tube, and end connects after protection tube, forms one section of pipeline section that diameter is larger.
Protection tube in the present invention can consist of continuously the pipeline section of different-diameter, so that its external surface forms ladder-type structure, is convenient to power tool and blocks.
In the present invention, protection tube can be one section or two sections, and while adopting one section, this section of protection tube can be coated on the one end being connected with male joint the contiguous male joint of body; Or the also contiguous female joint in the one end being connected with female joint that is coated on body.While adopting two sections, wherein one section of also contiguous male joint in the one end being connected with male joint that protection tube is coated on body, another section of protection tube is coated on the one end being connected with female joint the contiguous female joint of body.
The present invention is owing to being close to male joint or/and be coated with one section of protection tube on the body of contiguous female joint, when work, drilling tool is to be clipped on protection tube, rather than directly contact with body, so just having reduced drilling rod is bitten and squeezes the probability of ruining by instrument, can reduce drill pipe body abnormal waste and break, reducing the drilling failure that lost efficacy and cause due to drilling rod, and the application life of having improved drilling rod.
