Abstract
The utility model relates to a bundling type chambering drilling tool, which comprises a bundling drilling tool mandrel and a plurality of ultra-short drilling tools, wherein the ultra-short drilling tools surround the outer side of the bundling drilling tool mandrel and fixed with a mandrel shell, the ultra-short drilling tools are all communicated with the mandrel via water holes, each ultra-short drilling tool is provided with a drill bit interface, the drill bit interface can be externally connected with a corresponding drill bit, the mandrel and each ultra-short drilling tool are driven by a power machine to rotate around the centre line of the mandrel, mud fluid entering from the mandrel into each ultra-short drilling tool drives the drill bit to rotate automatically around the mandrel of the ultra-short drilling tool via a hydraulic motor, and the drill bits of the ultra-short drilling tools are maintained synchronous via gear transmission systems. In the utility model, a screw drilling tool is bundled into the chambering drilling tool, the drill bit is driven by the screw drilling tool to rotate actively so as to provide main power for rock breaking and chambering, required revolution torsion has little relationship with chambering diameter, one-step chambering amount is greatly increased, and the drilling tool is particularly suitable for medium and large-aperture chambering, greatly shortens the construction period and has significant economic benefits.
Description
Technical field
The utility model relates to a kind of drilling tool, particularly relates to a kind of cluster type borehole-enlarging drilling tool.
Background technology
Continuous development along with petroleum natural gas exploration technology, drilling technology, directional well, obtain more and more widely application from drilling technologies such as formula well, horizontal wells, traditional screw rod borehole-enlarging drilling tool gear wheel can only passive rotation, reaming power comes from the revolution of drilling tool, required operation torque is directly proportional with counter bore diameter and reaming amount, rotating speed is low, and for the large aperture and need the multiple fractionation reaming, extremely low with traditional borehole-enlarging drilling tool efficient.
The utility model content
For addressing the above problem, the utility model provides a kind of rotating speed height, cluster type borehole-enlarging drilling tool that production efficiency is high.
A kind of cluster type borehole-enlarging drilling tool of the present utility model, comprise boundling drilling tool mandrel and a plurality of ultrashort drilling tool, described a plurality of ultrashort drilling tool is centered around the outside of boundling drilling tool mandrel and is fixed together with the mandrel housing, ultrashort drilling tool all communicates by water hole with mandrel, on described each ultrashort drilling tool, all be provided with the drill bit interface, the drill bit interface can external corresponding drill bit, described mandrel and each ultrashort drilling tool are driven around the rotation of mandrel center line by engine, the mud liquid that enters each ultrashort drilling tool from mandrel passes through the fluid motor-driven drill bit around the axle center rotation of ultrashort drilling tool, keeps each drill bit synchronous by gear train assembly between a plurality of ultrashort drilling tools.
A kind of cluster type borehole-enlarging drilling tool of the present utility model, described a plurality of ultrashort drilling tools are evenly distributed on the external surface of boundling drilling tool mandrel.
A kind of cluster type borehole-enlarging drilling tool of the present utility model, the outer setting of described ultrashort drilling tool has preceding centralizer.
The beneficial effect of the utility model cluster type borehole-enlarging drilling tool is: the utility model is that the helicoid hydraulic motor boundling is become borehole-enlarging drilling tool, drive initiatively rotation of gear wheel by helicoid hydraulic motor, be broken the major impetus of rock, reaming, required revolution moment of torsion and counter bore diameter relation are little, one time the reaming amount significantly improves, reaming efficient improves several times, in being particularly suited for, the reaming of large aperture.Significantly shorten the duration of a project, remarkable in economical benefits.
Description of drawings
Fig. 1 is the structure sectional view of the utility model cluster type borehole-enlarging drilling tool.
The specific embodiment
Below in conjunction with Figure of description the utility model cluster type borehole-enlarging drilling tool is described further.
Referring to Fig. 1, a kind of cluster type borehole-enlarging drilling tool of the present utility model, comprise boundling drilling tool mandrel 1 and a plurality of ultrashort drilling tool 5, the outer setting of ultrashort drilling tool 5 has preceding centralizer 4, described a plurality of ultrashort drilling tool 5 is centered around the outside of boundling drilling tool mandrel 1 and is fixed together with the mandrel housing, ultrashort drilling tool 5 all communicates by water hole 6 with mandrel, on described each ultrashort drilling tool 5, all be provided with drill bit interface 3, drill bit interface 3 can external corresponding drill bit, described mandrel 1 and each ultrashort drilling tool 5 are driven by engine and rotate around the mandrel center line, the mud liquid that enters each ultrashort drilling tool 5 from mandrel 1 passes through the fluid motor-driven drill bit around the axle center rotation of ultrashort drilling tool, keeps each drill bits synchronous by gear train assembly 2 between a plurality of ultrashort drilling tools 5.
The utility model is that the helicoid hydraulic motor boundling is become borehole-enlarging drilling tool, drive initiatively rotation of gear wheel by helicoid hydraulic motor, be broken the major impetus of rock, reaming, required revolution moment of torsion and counter bore diameter relation are little, one time the reaming amount significantly improves, and reaming efficient improves several times, in being particularly suited for, the reaming of large aperture, significantly shorten the duration of a project, remarkable in economical benefits.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
