The fixed present invention.
Embodiment
Pass apparatus and method, including coding system under a kind of information based on RPM as Figure 1-3, top is driven, drilling rod, well
Lower RPM signal receptor, coding system is driven with top and is connected, and top is driven and is connected with drilling rod, and drilling rod connects with down-hole RPM signal receptor
Connect, coding system modulation signals, be delivered to top and drive, control Top Drive RPM, and then control rod rotation speed, down-hole RPM signal
Receptor receives rod rotation speed signal.
Top is driven includes that control system is driven on top, and coding system is driven control system and is connected with top, coding system modulation signals,
Pass to top and drive control system, control Top Drive RPM, and then control rod rotation speed, down-hole RPM signal receptor receives rod rotation speed
Signal.
Coding system：The input information of engineer or intelligent drilling system is processed, being converted into top drive control system can
With the control signal for recognizing, the control signal can be made up of the lasting duration of a series of Top Drive RPM and rotating speed, be formed
Corresponding information；
Drive control system in top：Top Drive RPM is adjusted, the system can recognize the rotary speed information that ground coding/decoding system is transmitted, adjusted
The rotating speed that top is driven；
Drill string：For transmitting rotating speed, moment of torsion, while being also used as the carrier of information transfer；
Down-hole RPM signal receptor：Using gyroscope or other inertance elements etc. the rotating speed of drilling rod is measured and recorded, and
Effective data are demodulated according to stipulations, the control information of downhole tool is formed.
Ground Engineer or intelligent drilling system determine control downhole tool according to current drilling well situation and Drilling Design
Information, the such as pose adjustment information of instrument.Coding system converts this information into top and drives the control that control system can be recognized
Signal processed, is transferred to top and drives, and top drives control system according to these control signals to adjust Top Drive RPM, and top is driven and drives drilling rod, bores
Bar will be rotated with same rotating speed, and the rotating speed of underground receiver measurement drilling rod is simultaneously recorded to rotary speed data, is solved
Adjust, complete to be passed under information.
In in order to modulate the signal to drill string rotating speed, Top Drive RPM can creep at a high speed and under low speed two states, can
" 1 " is represented by defining high rotating speed certain time, the slow-speed of revolution continues same time can represent " 0 ".As shown in Fig. 2 top
Drive under the rotating speed of 60r/min, continue 10 seconds, represent " 1 ", under the rotating speed of 40r/min, continue 10 seconds, represent " 0 ".
As shown in Figure 2, if it is desired to down-transmitting data " 1011101 ", top drive control system will be according to the data by Top Drive RPM
Following rotating speed sequential is adjusted to,
（1）Top Drive RPM is controlled under the rotating speed of 60r/min, to continue 10 seconds；
