Description
Technical field
It the utility model is related to field of petroleum machinery, more particularly to a kind of heat-insulated good air screw rod drill tool.
Background technology
The research and development of air screw rod drill tool be the Oil/gas Well based on oil field arrived the exploitation later stage seriously lose return, with foam spiral shell
A kind of helicoid hydraulic motor researched and developed in the case of bar drill is all unsatisfactory, is rotated by air driven helicoid hydraulic motor, so as to produce
Chip is taken out of pit shaft by raw moment of torsion to bore mill well drop point fish and other solid contents, then by air-flow, so as to reach volume increase, synergy
Purpose, but because the power source of air screw drilling is compressed air, its own temperature will after not only air is compressed
Rise, and the screw drill that it does not have liquid driven can produce good cooling effect to drill body like that, so easily boring
The problem of temperature is too high, influences the service life of screw drill, and operating efficiency is low.
Utility model content
The purpose of the utility model be for overcome the deficiencies in the prior art and provide it is a kind of it is rational in infrastructure, heat-proof quality is good,
The heat-insulated good air screw rod drill tool that service life is long, operating efficiency is high.
To reach above-mentioned purpose, the utility model employs following technical scheme.
A kind of heat-insulated good air screw rod drill tool, including it is by-passing valve, sleeve pipe, universal drive shaft, power transmission shaft, drilling rod, stator, wear-resisting
Layer, rotor, upper cutting ferrule, lower cutting ferrule, fixing bolt, thermal insulation layer and sealing ring, the upper end of described sleeve pipe by upper cutting ferrule with it is described
By-passing valve is connected；The lower end of described sleeve pipe is connected with universal drive shaft by lower cutting ferrule；The bottom of the universal drive shaft passes through power transmission shaft
Linked together with the drilling rod；Described sleeve pipe is internally provided with stator；The diameter of the stator is less than the straight of described sleeve pipe
Footpath；The fixing bolt is connected after passing through described sleeve pipe with the stator；Be provided with the inner hole wall of the stator one layer it is wear-resisting
Layer；The rotor is movably arranged on the stator interior；Thermal insulation layer is filled between the stator and described sleeve pipe；It is described heat-insulated
The upper and lower side of layer is mounted on sealing ring.
As further improvement of the utility model, the thermal insulation layer is that the filling of ceramic material particle forms.
Due to the utilization of above-mentioned technical proposal, beneficial technique effect that the utility model has：Technical side of the present utility model
Case, which employs, is arranged on stator and rotor in sleeve pipe, and is reserved with space between internal surface of sleeve pipe and the outer wall of stator and is filled out
Fill for thermal insulation layer, there is the heat exchange reduced outside drilling rod with inner rotator and stator, reduce the influence of external temperature
Advantageous effects；The mode that the technical program is fixed using upper and lower cutting ferrule and fixing bolt through sleeve pipe with rotor, tool
Have stable connection firmly, change convenient disassembly advantageous effects；The thermal insulation layer of the technical program is using potsherd
Filling, the advantageous effects of good heat-insulation effect low with packing material cost.
