(54) MULTI-CHANNEL DEVICE FOR REGISTRATION OF RESULTS OF INDUSTRIAL AND GEOPHIEICHBIAN

R

"/

The invention relates to geophysical instrument making and is intended for recording and processing geophysical information in digital form in a well logging process.

A device with a mechanical method of combining information on depth and photoregulation is known. til.

The disadvantages of such a device are low reliability, complexity of retrofitting and high precision alignment.

It is also known a device for recording the results of field geophysical research, in which the problem is posed by electronic means, containing preamplifiers connected via electronic keys and a tator of channels with analog-code transformer, magnetic recorder, depth coder and memory cube between the PACK and the magnetic recorder. Such a device makes it possible to obtain information combined in depth on a magnetic tape, and is used in the composition of logging geophysical stations in conjunction with a logging oscilloscope, plotter, etc. (2). RESEARCH

The disadvantages of this device are the lack of coordination between the output unit (magnetic recorder) and the secondary device (light beam oscillograph, plotter, etc.) 4 precisely between the speed of the information recorded by the magnetic recorder and the capabilities of the light beam oscilloscope, and the impossibility of combining the previously recorded magnetic information tape without its depth matching.

The purpose of the invention is to expand the functional capabilities of the device by ensuring its operability at various rates of issuing, receiving and combining information that is not previously agreed in depth. .

20 The goal is achieved by the fact that a multichannel device for recording the results of geophysical surveys containing preliminary

2 $ amplifiers connected via a KOtwytator of channels with a PAK, a magnetic digital recorder, whose inputs are connected to a depth encoder, a memory cube and a control unit, the outputs of which are connected to .1

memory, channel switch and PAK. and the inputs are with a memory cube and input terminals, the first of which is connected to the azhfrator of depth, as well as the output terminals, which are connected by two first and second inputs to the control unit of the 2I-OR cell, one of which is connected to the third input the output of the PLC and the second with the output of the cube, four inputs of both are connected to the output of the magnetic recorder, while the output of the first cell is connected to the input of the memory cube, and the second to the output 1 terminals of the device.

The drawing shows the block diagram of the proposed device,

The device contains a preliminary; amplifiers 1, commutator 2 channel, ILC 3, cube 4 pairs, control unit 5, encoder 6 depths, magnet digital recorder 7, cells 2 H-YALI 8 and 9, pkodike 10 and 11 and H11 input 2 klsmmm.

The device works in a slouchy way,

The register; signals are continuously accessed, io, gyyyyygredvarptelnyh amplifier. 1 and from the output through the switch 2 kanalol are fed to the PLC. The operation is arranged synchronized with pulses of CAT 11T51-1 pin depth, which are fed to the terminal 10. Mmpulsy icDanTODiunin also go to ROCH (Uf () | .TOTO b depth of formation KO / fi deaf and on the unit 5 upraplet (ig1. Plok 5 uprshlenip produces kg; mail1 uprai.geni immutator 2 kanitor, 1LK 3, cube 4 pm and a magnetic rostorpgorom 7. For each sq-ft depth switch 2 channels alternately key switch. signals to PL1, dd "they are converted to code.

In the recording mode, the code through cell 8 enters the cube 4 of the memory, where it is delayed by the depth of the fault, caused by the block 5, and then the recorder 7 for the record is received. In the case where the value of Gzadv; The kuPe pggm ty is equal to zero, the information us the magnetic tape is written without matching at the depth,

Depending on JMiif paHHoro rszhiia and the passage of specific information occurs in a slip way. In the first section of the tutorial - the ro-histrator 7 H42SiKa 9-gee some km.MLI 12, and the second and the trot from the luchapkh - the recorder 7-lchg1y / 1: a 8 - if.vfi 4

The memory is 9-output terminals 12. In this case, the second and third options are different in that in the second one, in the cube of 4 memories, the information is matched in depth, and, in the third, the information is accumulated and issued synchronously on request to input terminal 11, All control commands in recording and playback modes, delay values and sample addresses from the memory cube

o are formed in control block 5.

The proposed device allows an express analysis of the data obtained in the logging process, which increases productivity by 1.4 times.
