Description
Technical field
This utility model belongs to petroleum works field, especially relates to a kind of pushing away for intelligent drilling instrument
By mechanism.
Background technology
Intelligent drilling instrument guides control basic thought
After Xie, transmitting a signal to control unit, control unit will control hydraulic work system, by controlling
Electromagnetic valve to provide corresponding piston hydraulic thrust, thus will push against the wing and release, and the backup wing will be supported on
On the borehole wall, prevent housing from rotating, and give brill first side force, make drill bit return to correct course bearing.
The backup wing structure of existing intelligent drilling instrument, owing in drilling process, the backup wing can work frequently
Make so that connect the pin stress repeatedly of the backup wing and steering tool, easily cause pin forced breakage,
Thus intelligent drilling instrument can be caused to be hampered in drilling operation course the situation of card.
Summary of the invention
In view of this, this utility model is directed to a kind of backup mechanism for intelligent drilling instrument, with
Improve reliability and safety during intelligent drilling tool work.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
A kind of backup mechanism for intelligent drilling instrument, including the backup wing 1, fixed pin shaft 6, locking
Nut 5, screw 2 and helical spring 3, one end of the described backup wing 1 is by fixed pin shaft 6 and locking screw
Female 5 are connected with drilling tool body, and the other end is connected with described drilling tool body by described screw 2,
Being provided with described helical spring 3 between described screw 2 and described drilling tool body, the described backup wing 1 exists
The lower state keeping regaining of common effect of screw 2 and helical spring 3.
Further, the described backup wing 1 is provided with and accommodates the recessed of described screw 2 and described helical spring 3
Groove, makes described screw 2 not protrude from the outer surface of the described backup wing 1.
Further, the two sides of the described backup wing 1 were provided with the long hole slot 4 of mud.
Further, the position that the inner surface of the backup wing 1 contacts with tool body upper piston is provided with Laser Welding
The wearing layer 1 connect.
Further, the position that the outer surface of the backup wing 1 contacts with the borehole wall is provided with the wearing layer of laser welding
27.
Further, wearing layer 1, wearing layer 27 thickness are 0.5mm.
Relative to prior art, the backup mechanism for intelligent drilling instrument described in the utility model has
Following advantage:
(1) the backup wing of the present invention is evenly arranged in around drilling tool, and the backup wing is at screw
Effect is lower to be fixed with drilling tool, is released by piston during work, and helical spring is compacted, pushes away At All Other Times
Under the effect of helical spring, keep the state regained by the wing, make the external diameter being made up of the backup wing less than well head
External diameter, it is to avoid bore under intelligent drilling instrument and carry and occur during brill the backup wing to be hampered the situation of card.
(2) backup wing inner and outer surfaces of the present invention is equipped with the wearing layer of laser welding, to increase
The wearability of the strong backup wing, improves service life.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing,
Schematic description and description of the present utility model is used for explaining this utility model, is not intended that this reality
With novel improper restriction.In the accompanying drawings:
Fig. 1 is the backup mechanism front view for intelligent drilling instrument of the present utility model；
Fig. 2 is the backup mechanism top view for intelligent drilling instrument of the present utility model；
Fig. 3 is the backup mechanism upward view for intelligent drilling instrument of the present utility model.
Description of reference numerals:
The 1-backup wing；2-screw；3-helical spring；The long hole slot of 4-；5-locking nut；6-fixed pin shaft；
7-wearing layer two；8-wearing layer one.
Detailed description of the invention
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Intelligent drilling instrument of the present utility model guides control operation principle: when well track deflection
After setting value, one or two guiding hydraulic cylinder piston on floating guiding set stretches out support well
Wall, produces the guiding concentration power that skew direction actual with well is contrary, well track is entangled and returns to correctly
Direction.
Backup mechanism for intelligent drilling instrument of the present utility model, mainly by the backup wing, fixed pin shaft,
Locking nut, screw, helical spring form, with fixed pin shaft and locking nut will push against one end of the wing with
Tool body connects, and the other end screw of the backup wing is connected with tool body, screw and tool body it
Between be provided with helical spring；The two sides of the backup wing were provided with the long hole slot of mud；Release position at the backup wing
Put surface and the surface that contacts with the borehole wall is provided with the wearing layer of laser welding, strengthen the wearability of the backup wing.
Present configuration is simple, highly reliable, and can reduce when intelligent drilling instrument carries out drillng operation because of backup
Wing stress is excessive causes the risk of blocked portion after deformation.
Preferably, uniform 4 backup wings on intelligent drilling instrument.When the backup wing is installed on drilling tool
Afterwards, under the screw effect with helical spring, the state (being close to instrument) regained, its external diameter are kept
Less than outside diameter, reduce the risk of the backup wing and borehole wall generation friction, it is to avoid bore under intelligent drilling instrument
And carry and occur during brill the backup wing to be hampered the situation of card.The backup wing 1 is provided with receiving screw 2 and spiral shell
The groove of rotation spring 3, makes described screw 2 not protrude from the outer surface of the described backup wing 1, helical spring
The Elastic penetration of 3 is more than the ultimate range of the backup wing 1 with the borehole wall；The head diameter of screw 2 is more than spiral shell
The external diameter of rotation spring 3, the major diameter of thread of screw 2 is less than the internal diameter of helical spring 3.At drilling tool
The place that piston contacts with the backup wing 1 is provided with the wearing layer of laser welding, and the backup wing 1 is under piston effect
Also be provided with wearing layer after release with borehole wall contact position, laser welding wearing layer more effectively improves the backup wing
In 1 service life, non-active place need not arrange wearing layer, reduces processing cost.
The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality
Type, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement made
Deng, within should be included in protection domain of the present utility model.
