Description
Technical field
The present invention relates to directional drilling technique field, specially a kind of drilling tool positioning and orienting device.
Background technique
Drilling operation is an important link in mineral exploration engineering construction, is the core of entire engineering.And drillhole curvature
It is then the important component in six indexs of drilling operation, hole deviation will will cause following two o'clock harm: (1) in geology work
Make aspect, the macrobending that drilled cannot be such that Geological Structural Forms and position is bent by design across scheduled structural belt；Drilling
Bending decreases or increases the spacing for controlling ore body, will cause the distortion of Mineral reserve calculation；Hole deviation makes predetermined inquire for
Ore bed played leakage.(2) in terms of drilling work, hole deviation crosses the increase of ambassador's drilling tool steering resistance, causes drilling tool in hole
Interior revolution is difficult；The excessive drilling tool that easily causes of hole deviation fractures, and lifting drilling tool is difficult；Hole deviation makes connecing for drilling tool and hole wall
Contact increases, and the pressure loss increases, rate of penetration decline；Hole wall collapse, chip off-falling, bit freezing, burying easily occurs in bending hole section
Etc. accidents, and be bent hole section processing accident more difficulty；When hole deviation is excessive to need well straightening, workload is increased.
Drillhole curvature is inseparable with the direction fixed relationship of drill bit, during Directional Drilling for Pipeline Crossing, is boring
In good pilot hole, is returned and expanded in native end installation reamer using the drilling rod passed through, returned after reaming drag oil transportation, appendix several times
Road is easy to appear drill bit offset issue in this process, so that hole deviation is excessive, the installation of drilling tool is difficult to reach high-precision
Quasi- purpose, is unable to ensure the verticality of drilling.
Summary of the invention
The purpose of the present invention is to provide a kind of drill bit positioning and orienting devices of drilling rod, to solve in above-mentioned background technique
In the existing drilling equipment proposed, during Directional Drilling for Pipeline Crossing, the easy deviation of drill bit, the excessive problem of hole deviation.
To achieve the above object, the invention provides the following technical scheme: including power drilling tool, guiding axis and borehole-enlarging drilling tool,
Guiding axis soil end be equipped with the first threaded connector, the power drilling tool outer cover on the first threaded connector of guiding axis,
The borehole-enlarging drilling tool is covered in guiding axis terminus inner, and the guiding axis outer surface offers three guiding gutters.
Preferably, the power drilling tool is rock bit drilling tool.
Preferably, borehole-enlarging drilling tool soil end is spirally connected by the internal screw thread of the second threaded connector and guiding shaft end, institute
State the threaded connector external thread bolt connection that borehole-enlarging drilling tool end passes through internal screw thread and drilling rod.
Preferably, the borehole-enlarging drilling tool is gear wheel borehole-enlarging drilling tool, and borehole-enlarging drilling tool outside diameter of mandrel and drilling rod outer diameter keep one
It causes.
Preferably, the first threaded connector of the guiding axis and the threaded connector model of drilling rod are consistent.
Compared with prior art, the beneficial effects of the present invention are: the drilling tool positioning and orienting device, structure setting is reasonable, behaviour
Make simply, high-precision purpose to be not achieved when solving the installation of general drilling tool, improves the accuracy of positioning and directing, while guiding axis
On the guiding gutter that opens up, by injecting flushing liquor in drilling rod in drilling process, under the action of drilling rod inside water pressure, guiding gutter makes
Water water conservancy diversion in must drilling goes out outside drilling, plays suspension effect, can quickly clean flushing liquor.
Detailed description of the invention
Fig. 1 is structure of the invention scheme of installation；
In figure: 1, power drilling tool, 2, borehole-enlarging drilling tool, 3, guiding axis, the 21, second threaded connector, 22, borehole-enlarging drilling tool end, 31,
First threaded connector, 32, three guiding gutters.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution: a kind of drilling tool positioning and orienting device, including power drilling tool 1,
Guiding axis 3 and borehole-enlarging drilling tool 2, the native end of the guiding axis 3 are equipped with the first threaded connector 31, and 1 outer cover of power drilling tool exists
On the first threaded connector of guiding axis 31,2 sets of the borehole-enlarging drilling tool in 3 terminus inner of guiding axis, 3 outer surface of guiding axis
Three guiding gutters 32 are offered, the power drilling tool 1 is rock bit drilling tool, and the native end of the borehole-enlarging drilling tool 2 passes through the second screw thread
Connector 21 and the internal screw thread of 3 end of guiding axis are spirally connected, and the borehole-enlarging drilling tool end 22 can be with the screw thread of drilling rod by internal screw thread
Connector external thread bolt connection, the borehole-enlarging drilling tool 2 is gear wheel borehole-enlarging drilling tool, and borehole-enlarging drilling tool outside diameter of mandrel and drilling rod outer diameter are protected
It holds unanimously, the first threaded connector 31 of the guiding axis 3 is consistent with the threaded connector model of drilling rod.
