Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:
Fig. 1 is the system construction drawing that the present invention impacts that sound wave wireless drilling transmits underground signal using impactor；
Fig. 2 is that impactor of the invention impacts acoustic signals and down-hole information combination principle schematic diagram.
Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
A specific embodiment of the invention.
Using impactor impact sound wave wireless drilling transmission underground signal system, as shown in Figure 1, include impactor,
Face reception device and measurement pipe nipple, sensor and the control circuit being arranged in drilling rod, the impactor are set to drilling rod
Nearly drill bit, the measurement pipe nipple are connected with sensor, the drilling track information of the measurement pipe nipple real-time measurement drill bit, and pass
Pass sensor, the sensor is by the drilling track information of acquisition, by simple coded treatment, convert information into two into
One group of signal (this process is automatically processed by the coded program in sensor) of system, and this signal is passed into control circuit, institute
State the work that control circuit mainly controls above-mentioned impactor, the binary signal that control circuit is converted according to down-hole information, rationally
Air demand (air hammer) or liquid supply rate (hydraulic impacter) are adjusted, so that impactor has different operation ranges, thus sharp
The binary signal of one group of amplification is generated with impact sound wave, to be formed the sound wave letter of one group of carrying drilling track information
Number, the acoustic signals can be transferred to ground receiving wastewater facility along drilling rod, believe eventually by ground receiver demodulation software sound wave
It number is handled, to restore down-hole drilling trace information.The system further includes the battery sleeve being set in drilling rod, short to measure
Section, sensor and control circuit power supply.
Drilling rod is no magnetic drilling rod.Due to creating a non-magnetic environment for Magnetic Measurement instrument, guaranteeing using no magnetic drilling rod
The data that Magnetic Measurement instrument measures are more true, accurate.Impactor uses air hammer or hydraulic impacter, Neng Gouti
For higher energy, it is ensured that effective transmission of signal.Drilling track signal is converted to binary signal, knows convenient for control circuit
Not.
It is short using measuring the present invention also provides the method using impactor impact sound wave wireless drilling transmission underground signal
The drilling track information for saving real-time measurement drill bit, after sensor translates the information into binary signal, then by control circuit root
According to above-mentioned binary signal, air demand (air hammer) or liquid supply rate (hydraulic impacter) are reasonably adjusted, so that impactor
There is different operation ranges, to generate the binary signal of one group of amplification using impact sound wave, is taken to be formed one group
Acoustic signals with drilling track information, the acoustic signals can be transferred to ground receiving wastewater facility along drilling rod, eventually by ground
Face receives demodulation software and restores down-hole information.
From the point of view of the working principle of impactor, stroke there are an attack time t, impactor since highest point,
It travels forward under the pressure difference effect of front and back chamber, after undergoing of short duration impact distance, impactor piston drives drill bit impact rock,
And it pauses the of short duration time；Subsequently, as preceding cavity pressure is greater than rear cavity pressure, impactor is reversely transported under the action of pressure difference
It is dynamic, and highest point and again undershoot are returned to, during which interval time is t.As shown in Fig. 2, the duty cycle of impactor is a kind of square
The form of shape wave, similar to the binary signal in program.
Working principle are as follows: the signal that sensor obtains measurement pipe nipple converts information into class by simple coded treatment
It is similar to binary one group of signal (this process is automatically processed by the coded program in sensor), and this signal is transmitted to control electricity
Road controls the closing situation of distributing valve by control circuit, thus controls air demand.Since impactor attack time t is short, punching
Frequency height is hit, therefore a series of t collection is combined into T, i.e., after impactor impacts a period of time T, by closing distributing valve, makes impactor
Stop a period of time, then proceedes to cycle operation.A period of time T so just includes that repeat impact t (such as Fig. 2) utilizes this letter
Single conversion is so that 0,1 information of down-hole information conversion is consistent with impactor duty cycle T.Since impactor energy is big, impact
Sound wave is strong, thus sound wave can along drill pipe transmission to ground (relay station can be arranged every several hundred meters on drilling rod when necessary), from
And it is installed in the reception device on kelly bar and receives.What ground receiving wastewater facility received is a series of discontinuity waves, this wave
The waveform rectangular wave that just Ying Yuyuan underground signal is converted is identical, and is the rectangular wave using impact sound wave amplification.Ground sound wave
After energy converter receives signal, it is filtered, handles to restore and obtain down-hole information.
The embodiment of the present invention is described with above attached drawing, but the invention is not limited to above-mentioned specific
Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art
Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much
Form, all of these belong to the protection of the present invention.
