Abstract
A collapsing and biting preventing aluminum alloy drilling rod comprises an aluminum alloy pipe body, a male connector and a female connector, wherein the male connector is connected to one end of the aluminum alloy pipe body, and the female connector is connected to the other end of the aluminum alloy pipe body. At least one end of the aluminum alloy pipe body is wrapped by a section of protection casing pipe. The protection casing pipe is a drilling rod-type alloy pipe, and is tightly connected with the pipe body in a hot assembling mode. Due to the fact that the part, close to the male connector or/and the female connector, of the pipe body is wrapped by the protection casing pipe, and in the process of working, a drilling tool clamps the protection casing pipe rather than make direct contact with the pipe body, the probability that the drilling rod is bit by the drilling tool is reduced, the abnormal shrinkage and abnormal fracture of the pipe body of the drilling rod can be reduced, the frequency of the drilling accidents caused by drilling rod failure is reduced, and the service life of the drilling rod is prolonged.
Description
Technical field
The utility model relates to a kind of drilling tool, and particularly a kind of anti-squeezing ruined the aluminium drill pipe that bites.
Background technology
Aluminium drill pipe has lightweight, flexible, corrosion resistant characteristics.Along with the development of drilling technology, aluminium drill pipe is used superior performance is arranged at some deep-wells with in having heavy corrosion chemistry stratum.But the characteristics that the aluminium alloy drill pipe body case hardness is lower, very easily bitten by drilling tool and squeeze and ruin, serious restriction generally popularization and the use of aluminium drill pipe.So how to improve anti-the squeezing of aluminium drill pipe, ruin the important topic that performance is aluminium drill pipe production research.
The utility model content
The purpose of this utility model, exactly in order to address the above problem, provide a kind of anti-squeezing to ruin the aluminium drill pipe that bites.
The purpose of this utility model is achieved in that a kind of anti-crowded aluminium drill pipe that bites of ruining, comprise the aluminium alloys body, be connected to the male joint of aluminium alloys body one end and the female joint that is connected to the aluminium alloys body other end, be coated with one section protection tube at least one end of aluminium alloys body.
Described protection tube is the compo pipe with drilling rod material of the same type.
Described protection tube is joined with the aluminium alloys body and closely is connected by hot charging.
Described aluminium alloys body is straight tube, and end forms one section pipeline section that diameter is larger after connecting protection tube.
The end be used to connecting protection tube of described aluminium alloys body is that interior thickening type and external diameter are less than middle body, after connecting protection tube, is consistent with the external diameter of middle body.
Described protection tube is one section, and this section protection tube is coated on the end be connected with male joint the contiguous male joint of aluminium alloys body.
Described protection tube is one section, and this section protection tube is coated on the end be connected with female joint the contiguous female joint of aluminium alloys body.
Described protection tube is two sections, wherein one section also contiguous male joint of the end be connected with male joint that protection tube is coated on the aluminium alloys body, and another section protection tube is coated on the end be connected with female joint the contiguous female joint of aluminium alloys body.
Compared with prior art, the utlity model has following advantage:
1, on the aluminium alloys body, one section alloy protective sleeve pipe of configuration can intercept drilling tool and contacts with the direct of body, the application life of raising aluminium drill pipe;
2, protection tube and body are joined with the aluminium alloys body and are combined by hot charging, have the effect of strengthening the aluminium alloys body.
The accompanying drawing explanation
Fig. 1 is the structural representation (body is straight pipe type) of the utility model one embodiment.
Fig. 2 is the structural representation (body is interior thickening type) of another embodiment of the utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2, anti-squeezing of the present utility model ruined the aluminium drill pipe that bites, the female joint 3 that comprises aluminium alloys body 1, is connected to the male joint 2 of aluminium alloys body one end and is connected to the aluminium alloys body other end, be coated with one section protection tube 4 at least one end of aluminium alloys body.The two ends of aluminium alloys body 1 are threaded with male joint 2, female joint 3 respectively.
Protection tube in the utility model is the compo pipe with drilling rod material of the same type.
Protection tube in the utility model is joined with the aluminium alloys body and closely is connected by hot charging.
As shown in Figure 1, the aluminium alloys body in the utility model can be straight tube, and end forms one section pipeline section that diameter is larger after connecting protection tube.
As shown in Figure 2, the aluminium alloys body in the utility model also can be done thickening in the end be used to connecting protection tube and the external diameter that will locate less than middle body, after connecting protection tube, is consistent with the external diameter of middle body.
In the utility model, protection tube can be one section or two sections, and while adopting one section, this section protection tube can be coated on the end be connected with male joint the contiguous male joint of aluminium alloys body; Or the also contiguous female joint of the end be connected with female joint that is coated on the aluminium alloys body.While adopting two sections, wherein one section also contiguous male joint of the end be connected with male joint that protection tube is coated on the aluminium alloys body, another section protection tube is coated on the end be connected with female joint the contiguous female joint of aluminium alloys body.
The utility model is owing to being close to male joint or/and be coated with one section protection tube on the aluminium alloys body of contiguous female joint, when work, drilling tool is to be clipped on protection tube, rather than directly contact with the aluminium alloys body, so just having reduced drilling rod is bitten and squeezes the probability of ruining by instrument, can reduce the 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.
