The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this kind is used for the high-speed transfer emitter of measurement while drilling, comprise a circuit and a power storehouse 5 that is built-in with data modulating-coding circuit and high-pressure shocking wave pulse generating circuit, and a columned high-pressure shocking wave impulse generator body 7 and a hollow be connected guide rod 4.Wherein, on described high-pressure shocking wave impulse generator body 7, have some shock wave generation passages 6 that pass through for mud liquid 2, but it is right all to be equipped with the high-voltage discharging electrode of some synchronous discharges in each described shock wave generation passage 6; Described connection guide rod 4 is fixed between high-pressure shocking wave impulse generator body 7 and circuit and the power storehouse 5, is connected in that the cable between the circuit passes through from the described center that is connected guide rod 4 in described high-voltage discharging electrode pair and circuit and the power storehouse 5.
In addition, the principle of compositionality figure of described data modulating-coding circuit and high-pressure shocking wave pulse generating circuit as shown in Figure 2.Plain statement is as follows: foregoing circuit can be divided into two parts, first is digital distribution and the digital drive circuit that is used for the data modulating-coding, it mainly is made up of " sensor interface ", " data modulating-coding ", " sync driver " and unit such as " power amplifiers ", wherein, there are several passages will dispose the digital distribution and the digital drive circuit of equal number on the high-pressure shocking wave impulse generator body.The second portion of circuit is to be made of " power supply " and " high pressure generator " 2 unit, and the output of high pressure generator is connected to the power supply utmost point of power amplifier so that provide high voltage source for power amplifier.The data that single-chip microcomputer in the data modulating-coding unit is measured by " sensor data interface " unit production wells lower sensor, then data are modulated into the pulse code sequence, afterwards again by the corresponding shock wave pulse generator that drives of sync driver, sync driver drives the power amplification circuit of 3000-5000V respectively, high voltage discharge circuit independent of each other but that controlled by a sync driver is simultaneously arranged in every group of high-voltage power amplifying circuit, each independently high voltage discharge circuit all be connected with pair of electrodes, to realize the discharge simultaneously under the control of sync driver of electrode pair in the same shock wave generation passage, the function of accumulation of energy simultaneously.
Provide a specific embodiment of this programme below, be that the right quantity of high-voltage discharging electrode that described shock wave generation passage 6 is built-in with is 3, be respectively the upper strata sparking electrode to 3, the middle level sparking electrode to 8 and lower floor's sparking electrode to 9, the quantity of the shock wave generation passage 6 that has on described high-pressure shocking wave impulse generator body 7 then is 4.
So the reason of determining is: the number of shock wave generation passage will cooperate circuit design, and the quantity that increases passage can make each passage high voltage discharge circuit have the enough accumulation of energy time to help the lifting of discharge voltage.Installing in same passage manyly has two favourable parts to electrode: at first be by many electrode to be produced the shock strength that the stack of shock pulse can be strengthened producing synchronously; In a single day secondly, in same passage, there is pair of electrodes to damage, also has other, do not influence the generation of this passage shock pulse electrode work.
In this example, because the shock wave pulse generator has adopted four pulse generation passages, so pulse can be by the 8-4-2-1 coded format, one group of complete coding is totally four binary code positions, these four binary code positions are distributed on four delivery outlets of single-chip microcomputer, and each delivery outlet drives a sync driver; Four corresponding four shock wave pulse generators of sync driver, four sync drivers drive the power amplification circuit of four groups of 3000-5000V respectively, have three independently but simultaneously by the high voltage discharge circuit of a sync driver control in every group of high-voltage power amplifying circuit.Three independent high voltage discharge circuit discharge accumulation of energys simultaneously simultaneously under the control of sync driver
This device needs as shown in Figure 1 when using, and places in the drill string hydrophthalmia 1.Simply provide the course of work after this device adopts the 8-4-2-1 coding below.First of 8-4-2-1 coded digital " 1101 " is " 1 ", single-chip microcomputer is then opened the sync driver of No. 1 passage to the sync driver output driving pulse of No. 1 passage, this moment, " power amplifier " of No. 1 passage produced electrion by " electrode pair " that is attached thereto, owing to there is mud to flow through from No. 1 passage, the high-voltage arc that takes place on the electrode pair of No. 1 passage will produce a blast impulse pulse in mud like this; In like manner after producing a blast impulse pulse, No. 1 passage also produce a firing pulse according to No. 2 passage under second control of bits of coded at single-chip microcomputer; Because the 3rd bits of coded is " 0 " single-chip microcomputer only to be controlled time delay and send out driving pulse for the sync driver of No. 3 passage, such No. 3 passage just do not produce firing pulse; Then the 4th bits of coded is " 1 ", and No. 4 passage repeats the course of work of No. 1 passage and No. 2 passage under Single-chip Controlling, and also produces firing pulse in No. 4 passage.Behind four passage rotation work one-periods, in the drill string hydrophthalmia, just have one group of shock wave pulse by 8-4-2-1 digital coding sequence spread.Afterwards, shock wave pulse will be uploaded along the drill string hydrophthalmia in mud, and this like this shock wave with specific coding sequence will be transferred to ground to the information that downhole sensor collects.Because shock wave pulse width, intensity height, shock wave pressure at the clock place can reach 30-50MP, therefore, the transfer rate of the shock wave sequence of process coding can reach more than 1K bps, has improved the data transmission bauds in the mud-pulse transmission technology greatly.
