107 and stored, if not needing to supplement, terminates collection process.
The course of work of pressure break well test data wireless transmitting system provided by the invention based on mobile relay is as follows:
When needing to obtain downhole data, above-ground launcher 110 refers to the mobile communication control transmission of pipe nipple 103 at this time
It enables, wakes up mobile communication and control pipe nipple 103, the release at equal intervals of mobile communication control pipe nipple 103 one by one is stored in the pipe nipple
Mobile relay 107, discharge the frequency of mobile relay 107 by depending on the rate that needs, if necessary to the transmission of low rate, then often
The time interval of two mobile relays 107 can be longer, guarantees that its distance at 100~200 meters or so, is passed if necessary to high-speed
It is defeated, its time interval can be made shorter, guarantee distance at 50 meters or so.
The mobile relay 107 of release enters in annular space, and as the drilling fluid in annular space flows to the ground, due to movement
The 107 approximately equidistant arrangements in annular space are relayed, can be considered transmission trunking device, mobile communication controls pipe nipple 103 in release foot
After enough mobile relays 107, underground can be made to form one with ground and led to by the data force transfer that multiple mobile relays 107 form
Road, mobile communication control pipe nipple 103 and send instruction to data acquisition pipe nipple 105, and data acquisition pipe nipple 105 leads to required data
It crosses wireless near field communication unit and is transferred to mobile communication control pipe nipple 103；Mobile communication control pipe nipple 103 is obtaining data
Afterwards, nearest mobile relay 107 is sent the data to, then each mobile relay 107 transmits upwards in turn, until ground communication
Reception device 111；
Ground is equipped with ground moving and relays recyclable device 109, the mobile relay 107 for reaching ground can be recovered by filtration.Benefit
The liquid in the pit shaft of recycling is screened with sieve, the adsorption function of magnet can also be used, by the mobile relay in liquid
107 captures；
Delivery device 108 is relayed containing ground moving in this programme, after the mobile relay in the pipe nipple of underground all discharges,
Mobile communication control pipe nipple 103 sends corresponding instruction to the ground, and ground can be as needed at this time, is launched by drill string to underground
Mobile relay 107；Mobile communication, which controls pipe nipple 103, has mobile relay capturing function, and mobile relay can be captured and stored
In pipe nipple, un-shifted communication control pipe nipple 103 is captured, and ground can be returned to circulation of drilling fluid and is recovered.
Ground sends to underground and instructs, on the preferable stratum of shallower or communication condition, can also ground by it is high-power,
Wireless low frequency long distance transmission, directly sends to underground and instructs；Pressure arteries and veins can also be formed by pressurizeing on ground to down-hole liquid
Punching is furnished with pressure inductor in Master Communications pipe nipple, when sensing the variation of fluid pressure in pit shaft, that is, obtains and refer to accordingly
It enables, is in a word exactly that instruction is passed to underground mobile communication by wireless means to control pipe nipple 103.
Mobile communication controls pipe nipple 103 and data acquisition pipe nipple 105 with designated position is arrived under underground equipment, and data acquisition is short
Section 105 starts to acquire data, and the data of acquisition may include the data such as down-hole pressure, temperature, be realized by corresponding sensor；It is mobile
Communication control pipe nipple 103 is in standby；When needing to acquire downhole data, can be passed through by Terrestrial Communication Transmit device 110
The wireless means such as LF communication, pressure pulse, mud-pulse, mobile tag emit data to mobile communication control pipe nipple 103 and pass
Defeated instruction；After mobile communication control pipe nipple 103 receives instruction, at random to annular space release mobile relay 107, the time of release is
At equal intervals, the frequency of release is by depending on the rate that needs, if necessary to the transmission of low rate, then time of every two mobile relay
Interval can be longer, guarantees that its distance at 100~200 meters or so, if necessary to high rate data transmission, can make its time interval shorter,
Guarantee distance at 50 meters or so, mobile relay 107-1,107-2,107-3 are in the equidistant arrangement of the approximation of annular space from bottom to top, shape
The wireless transmission channel delivered in relays at one；Mobile communication controls pipe nipple 103 while discharging mobile relay, adopts to data
Collect pipe nipple 105 and send instruction, after data acquisition pipe nipple 105 is connected to instruction, by wireless communication to mobile communication control pipe nipple 103
Data needed for sending；After mobile communication control pipe nipple 103 receives data, sent to the mobile relay 107-1 nearest from it
Data, mobile relay 107-1 after receiving the data, send to mobile relay 107-2, transmit upwards in turn, which can
Pass through tag addresses in communication protocol；Data are successively transferred to ground, are received by ground communication reception device 111, and be transferred to
Computer terminal is handled.Mobile relay 107 is circulated up with the drilling fluid of annular space, after reaching ground, can be recycled by ground
Device 109 is captured using sieve or magnetism, to be recycled.
After the mobile relay release in mobile communication control pipe nipple 103, it can be notified in last time communication
Ground, and notification data acquisition pipe nipple 105 stops transmission；Ground can relay delivery device 108 by ground moving and will weigh at this time
The mobile relay 107 that postpones is launched into tubing string, will be moved downward with the drilling fluid in tubing string, as shown in figure 1 downward
Shown in arrow, the mobile relay in tubing string can be controlled pipe nipple 103 by mobile communication and capture, and is stored in mobile communication control
