Abstract
The present invention provides a kind of wireless automatic orientation system attached to drills for controlled directional drilling.It has increased automatic directing controller (comprising automatic control circuit, motor and adjuster) and has constituted the closed loop automatic orientation system on present inventor's invention " electric current field pattern monitoring while drilling instrument " basis.Signal transmits and adopts electric current field pattern electromagnetic signal passage.Adjuster is made up of gear and worm type of reduction gearing; Automatic control circuit is made up of pulse period discriminating, forward switch, reverser and holding circuit.Controlled directional drilling uses this system further to realize with boring automatic orientation on the basis of wireless drilling monitoring.
Description
The present invention relates to a kind of wireless automatic orientation system attached to drills of controlled directional drilling.
Have some direction finders in the directional drilling both at home and abroad.These direction finders are the data by monitoring while drilling, adjust the orientation of deflecting tool in the hole by manually-operated.Information research is retrieved the report that newly provides is provided according to china geological science, does not also have the instrument and the device in deflecting tool orientation in the automatic adjustment hole at present both at home and abroad.
The purpose of this invention is on the basis of present inventor's invention " electric current field pattern monitoring while drilling instrument " utility model patent (902216554), for controlled directional drilling provides a kind of wireless automatic orientation system attached to drills, not only can realize the wireless drilling monitoring, and can realize with boring automatic orientation.
Structural principle of the present invention is seen accompanying drawing.Wherein 1 is theory diagram, and 2 is structure principle chart.Deflecting tool 1 is to detect and the control object, and tools for angle sensor 2 detects the orientation of deflecting tool 1 and the cycle of modulating transmitter 3 output electric pulses.The signal of telecommunication of output is sent to collecting electrode 5 and sends into receiver 6 through drill string 4 and stratum.Signal is after filtering, amplification, shaping, and by the orientation of the demonstration of the display above the receiver 6 deflecting tool, synchronous signal is admitted to automatic control circuit 7.The duty of automatic control circuit 7 control motor 8, again by adjuster 9, drill string 4 regulate deflecting tools 1 towards the angle.
By accompanying drawing as can be seen, by deflecting tool 1-tools for angle sensor 2-pulse signal transmitter 3-drill string 4-collecting electrode 5-receiver 6-automatic control circuit 7-motor 8-adjuster 9-drill string 4-deflecting tool 1, constitute closed loop automatic control system.
This invention realizes on " electric current field pattern monitoring while drilling instrument " basis.By 2 to 6 being electric current field pattern wireless drilling monitors, 7 to 9 is automatic directing controllers, and whole closed loop automatic orientation system not only can be realized the wireless drilling monitoring, and can realize with boring automatic orientation.
Its concrete structure and automatic control process are referring to 2 of accompanying drawing.
The pulse signal cycle T that pulse signal transmitter 3 sends is modulated by tools for angle sensor 2, when deflecting tool in the hole 1 is in design orientation (0 °), and T=T
0, not at design T＜T during the orientation
0Or＞T
0Pulse signal passes to ground without cable by drill string 4 and stratum.
Automatic control circuit 7 is made up of pulse period discriminator circuit 10, forward switch 11, reverser 12 and holding circuit 13.
Adjuster 6 is made up of gear 14 and worm type of reduction gearing 15.Be enclosed within on six side's vertical shafts 16 for hexagonal hole in the middle of the worm gear in 15, vertical shaft 16 is by chuck 17 chucking drill strings 4.Adjuster 9 is driven by motor 8, by drill string 4, the orientation of drilling tool in the adjustment hole forward or backwards.
Deflecting tool 1 is not or not the design orientation, if pulse signal cycle T＜T in the hole
0The time, 11 conductings of forward switch, motor 8 is done the forward adjusting through adjuster 9 and drill string 4 drive deflecting tools 1; T＞T
0The time reverser 12 conductings, motor 8 drives deflecting tools 1 through adjuster 9 and drill string 4 and does oppositely to regulate; T=T
0The time, adjuster 9 makes deflecting tool 1 maintain the design orientation by drilling tool in the self-locking action brake hole of worm and gear.
By the wireless drilling automatic direction finder that the present invention makes, simple in structure, dependable performance proves through pilot production, in the boring of drift angle 〉=3 °, orientation accuracy can reach ± and 3 °.
