Abstract
The present invention relates to a wireless automatic orientation system following a drill, which is provided for controlled directional drilling. The wireless automatic orientation system forms a closed loop automatic orientation system by increasing an automatic orientation controller (comprising an automatic control circuit, a motor and an adjustor) on the basis of a 'current field type monitor following a drill' which is invented by the inventor. Signal transmission adopts a current field type electromagnetic signal channel; the adjustor is composed of gears and worm-wheel worm reducers, and an automatic control circuit is composed of pulse period identification, a forward switch, a backward switch and a protective circuit. The controlled directional drilling can further realize automatic orientation following a drill on the basis of wireless monitoring following a drill by using the system.
Description
The present invention relates to a kind of wireless drilling automatic orientation device that is used for directional drilling.
The directed monitor of existing both at home and abroad several wireless drillings.90221655.1) and external hydraulic impulse type orientation with drilling instrument for example " the electric current field pattern monitoring while drilling instrument " of present inventor invention (patent No.:.These instruments have solved wireless orientation survey problem, but do not solve directed automatic control.
The external existing self-orientating patent of directed drilling.Adopt mud hydraulic impulse transmission signal as U.S. Pat 4854397, realize the automatic control of directed drilling by Electronic Control and hydraulic modulator.The patent SU972084A of the former Soviet Union provides a kind of automatic control system that worm gear bores directed drilling that is used for.The drill bit direction signal also is sent to ground by hydraulic impulse, drives the direction of drilling well rotating disk with drill bit in the automatic adjusting well by automatic control circuit.Signal all by the hydraulic impulse transmission, therefore, can not be used for air and foam well-flushing in these two patents; The US4854397 patent adopts hydraulic modulator, and SU972064A adopts rotating disk to make adjuster, therefore all can not be used to use the orientation of spindle-type drill to bore dark.
The objective of the invention is to be applicable to spindle-type drill and to allow to use mud, water, air, foam etc. to do the automatic orientation device of well-flushing medium for directional drilling provides a kind of.
To achieve these goals, invented the wireless drilling automatic orientation device that is used for directional drilling, form by the pulse signal transmitter in the hole and ground receiver and automatic regulator, it is characterized in that automatic regulator connects worm type of reduction gearing by gear and forms, the power shaft of gear is that the automatic control circuit of core passes through Motor Drive by the pulse period discriminator circuit, the output shaft of reducer is connected with drill string, thereby the rotating of motor stops to control by automatic control circuit.Automatic control circuit is made up of pulse period discriminator circuit, forward switch, reverser and holding circuit.Detect deflecting tool is also modulated the electromagnetic pulse of being launched by the pulse signal emitter towards the angle cycle by sensor in the hole.This signal is sent to the receiver on ground by drill string and stratum without cable.When the signal pulse cycle equated with the cycle of being scheduled to, show that deflecting tool just in time is in the orientation of design, automatic control circuit makes the motor stall of adjuster, by the self-locking action braking drilling tool of worm and gear; When the signal pulse cycle is greater than or less than the predetermined cycle, show deflecting tool higher the design orientation, at this moment automatic control circuit turn-on reversal or forward switch, make the motor counter-rotating of adjuster or just changeing, make drilling tool oppositely become the forward fine setting by gear and worm type of reduction gearing, vertical shaft, chuck, be transferred to the orientation of design up to deflecting tool, thereby realized the automatic control of drilling direction.
The present invention has been owing to adopted electromagnetic signal passage and pulse discrimination circuit correspondingly, thereby can use in various well-flushing media such as water, mud, air and foam; Owing to adopted the adjuster that can be assemblied on the vertical shaft, so can use in the directional drilling of spindle-type drill.
Below in conjunction with accompanying drawing implementation method of the present invention is described further.Accompanying drawing 1 is a theory diagram; Accompanying drawing 2 is a structure principle chart; Fig. 3 is the vertical view of adjuster; Fig. 4 is signal pulse figure; Fig. 5 is the Automatic Control Theory explanation.
Among Fig. 1, the detecting by tools for angle sensor 2 of deflecting tool 1, and the electric pulse cycle of modulation transmitter 3 outputs towards the angle.Electric impulse signal is sent to collecting electrode 5 and sends into receiver 6 through drill string 4 and stratum.Signal through after filtering, amplification, the shaping by the display display surface on the receiver 6 to the angle, synchronous signal is admitted to automatic control circuit 7.Automatically the duty of control circuit 7 system control motor 8, again by adjuster 9, drill string 4 regulate deflecting tools 1 towards the angle.
By accompanying drawing 1 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 the closed loop automatic control system device.
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 device not only can be realized the wireless drilling monitoring, and can realize with boring automatic orientation.
Its concrete structure and automatic control process with reference to the accompanying drawings 2.
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 orientation
0 °Pulse 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 protection electrical equipment 13.
Adjuster 9 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 the reducer 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 is (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 drilling rod 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.
