Accompanying drawing explanation
Fig. 1 is the structural representation of the drill rod assemblies of the rock engineering that the embodiment of the present invention provides；
Fig. 2 is the structural representation of the drilling rod extension that the embodiment of the present invention provides；
Fig. 3 is that the use of the drill rod assemblies of the rock engineering that the embodiment of the present invention provides is with reference to figure.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, the present invention is further elaborated.Should be appreciated that described herein specifically
Embodiment only in order to explain the present invention, is not intended to limit the present invention.
Embodiments provide the drill rod assemblies of a kind of rock engineering, the brill of this rock engineering
Bar assembly includes: the drilling rod alternately connected and drilling rod extension, drilling rod extension is surrounded with many
Individual external upset (EU) is protruding, and forms recessed flow path between two adjacent external upset (EU) projections.
Preferably, the two ends of described drilling rod are provided with external screw thread, and the two ends of described drilling rod extension are respectively
It is provided with the female thread matched with the external screw thread on described drilling rod.
Preferably, the length of the described external upset (EU) drilling rod extension length less than 1/3rd.
With reference to shown in Fig. 1 and Fig. 2, the drill rod assemblies 10 of rock engineering has elongated drilling rod 12
With at drilling rod extension 14.Drilling rod 12 has the first thread head 16, the second thread head 18, and
With constant external diameter.Drilling rod extension 14 has the first end of thread 20 and the second thread head 22.The
Two thread heads 22 are designed to engage matchingly the elongated drilling rod 12 of the first thread head 16.The
One end of thread 20 is adapted to engage in another drill bit part, the most elongated drilling rod 12, or, such as Fig. 1
Shown drilling rod extension 24.Drilling rod extension 24 has first thread head 30 and second end of thread
Portion 32.Second thread head 18 of the first thread head 32 and each drilling rod 12 connects, and drilling rod prolongs
Stretch the first and second thread heads that part 14 is identical with drilling rod extension 24, make them permissible respectively
It is connected to form the required length of assembly 10.Drilling rod extension 24 as shown in Figure 1 has perseverance
Fixed external diameter.
Drilling rod extension 14 has multiple external upset (EU) projection 26, and this external upset (EU) projection 26 is positioned at the first spiral shell
Between stricture of vagina end 20 and the second thread head 22.Preferably, external upset (EU) projection 26 be middle or
It can be what convenient position the most in office.And the two ends of external upset (EU) projection 26 have chamfering structure.
Recessed flow path 28 is formed, to prevent or to reduce hydraulic lifting between adjacent external upset (EU) projection 26
Effect.Recessed flow path 28 can be formed by machining polishing.Preferably, recessed flow path
The circumference that the circumference of 28 is protruding less than at least 65% external upset (EU).Ensure the external upset (EU) projection 26 of q.s
With holding load.As in figure 2 it is shown, the length drilling rod that the length of external upset (EU) projection 26 is less than 1/3rd
The length of extension 14.The thickness of external upset (EU) projection 26 is two inch thickness.It is preferable to carry out at one
Example, drilling rod can use in the pit shaft of 6.75 inch inner diameter, and drilling rod uses 5 Hes between 5.25
The external diameter of inch.In either case, external upset (EU) projection 26 is by close but less than housing internal diameter, about
Between 1/4th or half inches, such as 5.5 to 6.75 inches.In a preferred embodiment, outward
Thicken a diameter of the 5.5 of protruding 26.Preferably, drilling rod adnexa 14 and 24 is that length is less than 3 English
Chi is long, preferably from about 2 feet.Drilling rod adapter 14 and 24 also can as protection structure because they
May be removed, if it occur that the screw thread damaged can directly take off replacement.Thus avoid
The whole part drilling rod changed or transport drilling rod is needed to be processed to shop.On the contrary, drilling rod adapter 14
Can carry with 24 and making is more prone to.
Operation:
As it is shown on figure 3, during the drill rod assemblies 10 of rock engineering, major diameter is useful especially drilling rod
Being desirably in boring 34, it can have housing 36, the external diameter drilling rod 12 being i.e. relatively close to.Such as, bore
Bar 12 can have an external diameter of 5 inches, and the internal diameter 34 of wellhole or shell 36 (if present)
It is between 6 and 6.75 inches.In this case, outside angry typically at traditional drilling rod 12
Would potentially result in hydraulic fracture down-hole, wherein liquid can not flow through disturbance be lowered as drill bit string or
Raise.Drill rod assemblies 10 drops in well, and extra drilling rod extension 14 is added.Preferably,
Drilling rod extension 14 and 24 is connected on the surface of drilling rod 12, and the structure being then then attached to drill bit is made
It it is a single unit.As external upset (EU) projection 26 near the internal diameter 34 of wellhole, external upset (EU) is protruding
26 also can be as centralizer or stabilizer with stream.
These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Any amendment, equivalent and the improvement etc. made within bright spirit and principle, should be included in this
Within the protection domain of invention.
