Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
With reference to Fig. 1, device is passed under a kind of rotary steering drilling tool drilling fluid pulse signal, the standpipe 4 comprising drilling rod 1 and connected by hose 2, the upper end setting pressure sensor 3 of described standpipe 4, standpipe 4 below this pressure sensor 3 forms a bypass by threeway, and this bypass is provided with down and passes device; Pass device under this and comprise pneumatic control valve 6, this pneumatic control valve 6 is connected with impulse controller 9, and impulse controller 9 is connected with the man-machine interface 10 of surface computer system; The outlet line of described pneumatic control valve 6 inserts in slurry tank; Described pressure sensor 3, impulse controller 9 are connected with surface computer system by RS-485 or wireless transmitter receiver device.Connect slush pump 7 by the standpipe 4 of threeway, the suction line of this slush pump 7 inserts in slurry tank 8.
Pneumatic gate valve 5 installed by the pipeline at described pneumatic control valve 6 two ends, and this Pneumatic gate valve 5 is connected with impulse controller 9.This Pneumatic gate valve 5, as the use turned off when not using down and pass device, uses as passing down when device breaks down and keeps in repair in addition.
Workflow of the present utility model is as follows: (1) opens when slush pump 7, the pump of drilling fluid in slurry tank 8 according to 35Mpa is rushed, squeeze in the standpipe 4 of drilling well major loop, accessed down by high-pressure hose in the bypass that standpipe 4 lower end is formed by threeway and pass device.(2) when surface computer system assigns regulating command to pneumatic control valve 6, open down two the Pneumatic gate valve 5(passing device when normally using, two Pneumatic gate valve 5 standard-sized sheets simultaneously), a part of drilling fluid is flowed out from bypass.According to required pressure pulse parameter (pulse amplitude, pulse width, pulse frequency) accurate recording and backup relevant information; Then, surface computer system sends an instruction to impulse controller 9, and certain pulse action pressed by the relay above impulse controller 9, the signal lamp variable color in front.(3) pass down in device work, the pressure transmitter 3 that standpipe 4 upper end is installed records standpipe 4 operating pressure, feed back to surface computer system, this surface computer system calculates the applicable aperture of pneumatic control valve 6 according to the pressure pulse parameter of its feedback signal force value and setting.Control pneumatic control valve 6 "ON"-"Off"-"ON"-"Off", thus to the number of delivering a letter under the continuous multifrequency time pressure negative pulse required for rotary steering generation.
The selection of above-mentioned pneumatic control valve 6: pneumatic control valve is gas force open type, meet and use medium to be drilling fluid, this drilling fluid has certain viscosity, containing sand particles, additive, band is corrosive, high pressure reduction 35.0MPa to be born, resistance to lasting multifrequency time on/off operation simultaneously.The control valve speed of actions of Direct Travel is slow, and only having the control valve considering angle stroke, is 90 by the theoretical optimal value of force direction excursion (roll angle)
o.Consider from drilling fluid medium, have eccentric rotary valve and V-type ball valve suitable, but consider the opening soon continuously of valve, change stable principle characteristic, select eccentric rotary valve more suitable.Flexural strength 1500MPa, the high speed of medium is washed away, and the external surface of spool and endoporus carry out cure process, therefore adopts the integral sintered spool of YG8.Pneumatic control valve 6 is by realizing communication network on-the-spot and be connected under RS-485 standard, and it is provided with insulating ground loop.The sequential arranged installed by pneumatic control valve 6 is unlatching or closedown, and the opening time is T
on, shut-in time T
off, the time in seconds, passes the signal period, interim T under forming a complete pulse
on, T
offby the multiple lower teletype command of various arrangement combination revision for execution.
Pneumatic gate valve 5 selects one to be applicable to high pressure, the high-precision pressure acquisition system of high (low) temperature environment, has measuring-signal and amplifies modulate circuit, analog to digital conversion circuit, uses high accuracy, Low Drift Temperature device to reduce the sensor of temperature impact.Its precision can reach full scale 0.1%, and maximum operating temperature can reach-40 DEG C-100 DEG C, meets the requirement of closed loop pressure Survey control.PID control procedure of the present utility model is: pass through high pressure, the high-precision pressure acquisition system of high (low) temperature environment measures the pressure drop of standpipe mud pressure negative pulse along change, utilize ground-based computer PID to regulate pneumatic control valve aperture size to be fixed on exact position, meet and rotate downhole tool dependability.Obtain the time T between two negative pulses simultaneously, lower teletype command accuracy can be met by checking time parameters.
