Abstract
The invention relates to a drilling rod for drilling, in particular to the integrated wind-blade spiral drilling rod for air pressure drilling. In the prior art, blades of the spiral drilling rod are narrow; and during the drilling process, an inner wall of a drill hole is easy to be scratched, a holder and a centralizer of a drilling machine can not directly clamp the spiral drilling rod, while an external flat drilling rod is taken as an active drilling rod and connected with the spiral drilling rod for realizing drilling, thus causing low drilling efficiency. The integrated spiral drilling rod is of an integral structure composed of a male joint, a middle pipe body, a female joint and helical blades, wherein, continuous helical blades are arranged on the male joint, the middle pipe body and the female joint, and the axial width of the helical blades is greater than the radial height thereof. The spiral drilling rod of the invention has small hole-wall disturbance and high drilling efficiency, and can be directly applied to a drill chuck, the holder and the centralizer.
Description
Technical field
The present invention relates to a kind of drilling rod, is that a kind of blast creeps into wide blade integral formula auger stem specifically.
Technical background
The blade of auger stem is a narrow blades at present, in the drilling process, the boring inwall is easily by scratch, and the direct clamping auger stem of the clamper of rig and centralizer, but need outer flush drill stem to be connected with auger stem and can to creep into as kelly, cause drilling efficiency low.
Summary of the invention
The object of the present invention is to provide a kind of can be directly creeping into wide blade integral formula auger stem with the blast of rig clamping.
For achieving the above object, the technical solution used in the present invention is:
Blast creeps into wide blade integral formula auger stem, its special character is: described monolithic auger stem is a monolithic construction by male joint, middle body, female joint and helical blade, a continuous helical blade is set in described male joint, middle body and the female joint, and the axial width of described helical blade is 2-10 with the radial height ratio: 1.
The axial width of above-mentioned helical blade is 3-7 with the radial height ratio: 1.
Above-mentioned fillet of tool joint pins is to be threaded with the connected mode of female joint.
The present invention is with respect to prior art, and its advantage is as follows: wide blade is little to the hole wall disturbance, and can be directly used in chuck of rig, clamper and centralizer, the drilling efficiency height.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
The specific embodiment
Monolithic auger stem of the present invention is a monolithic construction by male joint 1, middle body 2, female joint 3 and helical blade 4, and male joint 1, female joint 3 and helical blade 4 directly process at the heavy wall body; A continuous helical blade 4 is set in described male joint 1, middle body 2 and the female joint 3, the axial width of described helical blade 4 is greater than its radial height, ratio is 2-10: 1, form the auger stem of wide blade, thereby little, and can be directly used in chuck of rig, clamper and centralizer to the hole wall disturbance.
The preferable axial width of helical blade of the present invention is 3-7 with the radial height ratio: 1.
Fillet of tool joint pins of the present invention adopts with the connected mode of female joint and is threaded, so sealing effectiveness is good, suitable blast creeps into.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
