Abstract
The utility model relates to a drilling drill pipe, in particular to an integral type wind-vane spiral drill pipe for wind pressure drilling. In the prior art, a vane of a spiral drill pipe is a narrow vane, and during a drilling process, the inner wall of a drill hole is easy to be scratched, a holder and a centralizer of a driller can not directly hold the spiral drill pipe and a flat drill pipe is needed to be utilized as a driving drill pipe to be connected with the spiral drill pipe so as to drill, thereby causing low drilling efficiency. The integral type wide-vane spiral drill pipe integrates a male joint, a middle pipe body, a female joint and a spiral vane, the male joint, the middle pipe body and the female joint are equipped with the continuous spiral vane, and axial width of the spiral vane is larger than radial height thereof. The spiral drill pipe is low in hole wall disturbance, can be directly used for a chuck of the driller, the holder and the centralizer, and is high in drilling efficiency.
Description
Technical field
The utility model 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.
The utility model content
The purpose of this utility model is to provide a kind of and can be directly creeps into wide blade integral formula auger stem with the blast of rig clamping.
For achieving the above object, the technical solution adopted in the utility model 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 utility model 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 utility model.
The specific embodiment
Monolithic auger stem of the present utility model 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 utility model is 3-7 with the radial height ratio: 1.
Fillet of tool joint pins of the present utility model 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 utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
