Taw qhia

Kev ntsuas GD-4 electromagnetic ntsuas raws li thiab hais txog cov txheej txheem uas hluav taws xob tiv thaiv tau txiav txim siab los ntawm kev ntsuas ntawm hluav taws xob thiab kev sib nqus cov cheeb tsam muaj feem xyuam rau cov khoom tshwm sim ("tellurics", vim feem ntau los ntawm hluav taws xob ntaus) ntws hauv av.


Nws muaj ntau yam xws li cov teeb liab siv zauv, kev siv lub tshuab ua haujlwm khiav lag luam hauv nruab nrab, kev lag luam hauv nruab nrab ntawm kev ua lag luam, kev ua haujlwm siab zoo, 32 A / D siab, thiab cov ntaub ntawv siv hluav taws xob, HMT), Nws tseem tuaj yeem tshawb tau zoo li suab magnetotelluric (AMT) thiab magnetotelluric (MT los yog LMT).

Cov ntawv thov rau AMT thiab HSAMT (GD-4)

1.Minerals thiab dej hauv kev tshawb kawm hauv av mus rau 1,500 m qhov tob.

2. Daws qhov chaw kawm ntawm engineering.

3. Kev kawm tshawb fawb.


Kev xav thiab kev txwv rau AMT thiab HSAMT

1. Data zoo rau cov AMT thiab cov qis qis ntawm HSAMT yog nyob ntawm seb muaj cov kev liaj teb li cas. Yam tshwm sim ntawm AMT yog nyob ntawm lub caij, lub sijhawm ntawm hnub, thiab huab cua.

2. Sib txuas lus los ntawm 50 Hz los yog 60 Hz zog xws li cov fais fab, cov khoom siv ua haujlwm, lossis cov chaw hauv nroog tsis zoo rau cov ntaub ntawv zoo.


Qhov zoo ntawm AMT thiab HSAMT ntau dua cov tswv yim zoo sib xws

1.AMT tshaaj yog ua sai dua cov kev cai MT. Nrhiav tau rau cov ntaub ntawv tsawg zaus MT yuav tsum tau txog li 12 teev ntawm ib qho chaw nres tsheb nkaus xwb. Sau cov ntaub ntawv high-zaus AMT ntawm 10 Hz thiab saum toj no yuav ua tau rau hauv dua 15 feeb.


2. Kev sib txuas lus hauv QHOV CHEEB TSAM kev sib txuas lus no yooj yim dua thiab yooj yim dua. Ib cov kab grounded dipole CSAMT transmitter tuaj yeem siv sij hawm ntau teev. Ib lub voj voog dual-loop ua lub vev-xaij tuaj yeem teem sijhawm ntev tshaj 10 feeb.


3.HSAMT tuaj yeem txiav txim siab ntiav. HSAMT nce txog 100 kHz tuaj yeem tsim lub hom phaj li ntiav li 5 meters. Traditional low-frequency MT tsis tau daws cov hom phiaj nyob rau hauv lub siab 100m. AMT rau 10 kHz yuav daws tau lub hom phaj li ntiav li 20 metres nyob hauv lub ntiaj teb.


4.AMT thiab HSAMT sensor teeb yog yooj yim dua. Traditional low-frequency MT kuaj yuav tsum tau sib nqus sensors mus faus tsawg kawg 20cm hauv av, uas yuav siv sij hawm ntau heev thiab tej zaum yuav tsis yooj yim hauv khov los yog lwm yam nyuaj hauv av. High-frequency AMT los yog HSAMT sib nqus sensors feem ntau siv tau tsis ruaj khov. MT electric sensors siv non-polarising porous lauj kaub electrodes uas yuav tsum tau faus hauv cov av hauv av. Cov AMT electrodes tuaj yeem yog hlau hlau uas tsuas yog hammered rau hauv av.
