Description
Technical field
The present invention relates to a kind of control system, be specifically related to a kind of drilling fluid wireless drilling instrument in the face of the control system of downhole instrumentSystem and control method.
Background technology
Drilling fluid wireless drilling instrument adopts powered battery, and in the time stopping boring, downhole instrument is not answered power consumption. For this reason, downhole instrumentWhether work and working method is controlled by ground, what control it is opening or stopping of slush pump. Slush pump leaves and stops, to down-holeImpact has two kinds, and one is slush pump while opening, and drilling rod (wireless drilling instrument is arranged on drilling rod) can shake because of mud flow;Another kind is that mud can circulate.
Conventionally adopted two kinds of methods to make downhole instrument receive the signal that slush pump is opened in the past, the one, in the circulating mud of down-holeA mechanical switch is installed, while circulating, switch conduction, otherwise just disconnected; The 2nd, on downhole instrument, install acceleration additionalSensor, judges whether accekeration determines slush pump work.
But in use procedure, above-mentioned two kinds of methods are all unstable, and the former often damages by mechanical switch, and the latter is under Holes of Complicated WellsUnder environment, instrument usually needs to install additional a large amount of damping devices, has directly caused instrument reaction sensibility inadequate, and work can notLean on, the well having is capable, and some wells are not all right, on same well, and some layer row, some layers are not all right. And this situation oneDawn occurs, and the drilling rod of several kms will be brought up from down-hole, after replacing instrument or mechanical switch, relays lower drilling rod again, everyInferior loss reaches several ten thousand yuan.
Summary of the invention
The object of the invention is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of drilling fluid wireless drilling instrument in the face of down-holeThe control system of instrument and control method.
For achieving the above object, the present invention adopts following technical proposals:
Drilling fluid wireless drilling instrument ground, in the face of the control system of downhole instrument, comprises the oscillating plate being arranged in centralizer, described in3-axis acceleration sensor and MCU are installed on oscillating plate, and described 3-axis acceleration sensor is connected to the AD conversion of MCUModule, what described MCU received ground slush pump opens, stops signal, and triggering signal is sent to wireless drilling instrument downhole instrument.
Described centralizer is fixed on the top of pressure-bearing pipe, pressure-bearing pipe inside be provided with successively from top to bottom seal shock-proof circle, damper,Connector and wireless drilling instrument downhole instrument.
Described control system and pressure-bearing Guan Jun are arranged at non magnetic drill collar central interior position.
Described non magnetic drill collar is installed between drill bit and drilling rod.
The control method of above-mentioned control system, step is as follows:
1) slush pump is opened, and centralizer vibrations, enter step 2); Slush pump is not opened, and centralizer does not have external force to make its vibrations,The work of wireless drilling instrument downhole instrument is shut down after the time delay setting in advance;
2) 3-axis acceleration sensor of centralizer internal vibration plate outputs signal to the AD modular converter of MCU, works as MCUWhen the signal strength signal intensity receiving is greater than settings, enter step 3);
3) shockproofness of the 3-axis acceleration sensor detecting according to AD modular converter, and predefined sensitivity,MCU exports a triggering signal, and is sent to wireless drilling instrument downhole instrument, thereby makes its work.
Operation principle of the present invention:
Make an oscillating plate, on this piece plate, 3-axis acceleration sensor and MCU are installed, 3-axis acceleration sensor is used forDetect the vibrations of all directions, MCU detects the shockproofness of 3-axis acceleration sensor by AD modular converter, and rootAccording to predefined sensitivity, export a triggering signal. Oscillating plate is arranged in the stable centralizer of vibrations to centralizerOriginal effect is that the various piece of wireless drilling instrument is coupled together, and makes instrument be placed in the device of non magnetic drill collar central authorities, and rightInstrument has cushioning effect, owing to connecting with connecting higher temperature line between the connector at centralizer two ends, therefore, is arranged on centralizerOscillating plate output just may pass through three connecting lines wherein, triggering signal is input to wireless drilling instrument downhole instrument, separatelyOutward, what MCU received ground slush pump opens, stops signal, thereby realize by slush pump control wireless drilling instrument downhole instrumentWhether work and working method.
Wireless drilling instrument when work, first by several parts of wireless drilling instrument downhole instrument (as inserting tube, driving, gamma,Pulser, battery etc.) be connected and installed with pressure-bearing pipe with centralizer together with, then the instrument being integrally connected is placed on without magnetic and is boredQuickly, non magnetic drill collar, as a part for drilling rod, is arranged between drill bit and drilling rod.
In drilling process, in the time that slush pump is not opened, mud does not flow, and centralizer does not have external force to make its vibrations, can not exportTriggering signal; In the time that slush pump is opened, mud can flow in non magnetic drill collar, and centralizer will be shaken, 3-axis accelerationSensor output signal is to the AD modular converter of MCU, when the signal strength signal intensity receiving as MCU is greater than settings, and MCUTriggering signal will be sent to wireless drilling instrument downhole instrument, thereby make its work. In the time that slush pump quits work, instrumentWork is shut down after the time delay setting in advance. In the course of the work, the opening time length of ground manual control slush pump,Can control the different operating mode of wireless drilling instrument downhole instrument.
The invention has the beneficial effects as follows, the present invention utilizes in centralizer oscillating plate is installed, and has both solved the problem of damping, again notCan cause that instrument reaction sensibility declines, thoroughly solve the unsettled problem of existing control system control procedure, realizeEffect is controlled reliably, improves drilling efficiency, saves human and material resources.
