Geophone Magnet

Geophone Magnet

Qhov kev thov kom raug thiab zoo ntawm seismic cov ntaub ntawv tau txais yog nce raws li geophysical tshawb nrhiav technology nce qib. Broadband, high-fidelity, siab teeb liab-rau-suab nrov piv, thiab siab dynamic cov ntaub ntawv yuav tsum tau los txheeb xyuas lithology, kua, thiab fractured reservoirs, uas txhim kho reservoir qhov chaw, yam ntxwv, kev sib txuas, thiab, thaum kawg, roj rov qab. Lub geophone yog ib qho kev tshaj lij sensor uas hloov cov tshuab hluav taws xob ntog mus rau lub teeb liab hluav taws xob, lossis lub tshuab hluav taws xob hloov hluav taws xob uas hloov cov tshuab hluav taws xob rau hluav taws xob. Nws yog ib qho tseem ceeb ntawm tag nrho cov seismic cov ntaub ntawv tau txais txheej txheem. Raws li lawv cov qauv kev khiav hauj lwm, geophones raug cais raws li electromagnetic induction, piezoelectric ceramic, MEMS, thiab fiber optics. Feem ntau hom yog hluav taws xob induction, thiab txav coil geophone yog tus sawv cev tshaj plaws.

Basic Structure thiab Txoj Cai Ua Haujlwm

Geophones tau muab faib ua ob hom: kev vibration systems thiab magnetic circuit systems. Lub plhaub yog ua los ntawm lub tog raj kheej-zoo li tus hlau mos, thiab lub midsection tsev muaj ib tug sib nqus Circuit Court system. Lub tshuab hluav taws xob sib nqus muaj cov hlau nplaum thiab ob tus ncej khau uas txuas nrog lub plhaub. Qhov chaw nruab nrab ntawm lub plhaub hlau mos thiab cov hlau nplaum geophone yog nyob ntawm qhov kev co, uas muaj cov kauj, coil txhawb nqa, thiab cov springs, uas ua ke ua ib lub cev coasting. Ntxig lub geophone vertically rau hauv qhov chaw, thiab lub geophone yuav ua ke nrog cov av ntawm lub plhaub lub plhaub. Nto vibration yuav ua rau muaj kev sib raug zoo ntawm lub coasting lub cev thiab lub plhaub, uas ua rau muaj kev sib txheeb ntawm cov coil nyob rau hauv lub magnetic teb thiab cov zis tam sim no teeb liab sib xws rau lub sij hawm vibration. Cov qauv ntawm underground strata yuav raug qhia tom qab ua tiav cov teeb liab.

Hais txog Geophone Magnet

Cov hlau nplaum geophone, raws li cov khoom lag luam tseem ceeb, tsis yog tsuas yog cuam tshuam cov ntsiab lus tseem ceeb thiab qhov ntsuas ntawm geophone, tab sis kuj yog nws cov nqi. Ntau hom hlau nplaum ruaj khov yuav muab cov yam ntxwv sib txawv ntawm geophone. Tsuas yog qhov ntsuas ntawm cov hlau nplaum txiav txim siab qhov sib txawv ntawm huab cua. Kev sib nqus tom qab, qhov kub thiab txias, kev cuam tshuam ntawm electromagnetic, thiab kev co yuav cuam tshuam rau huab cua sib txawv, ua rau cov geophone tsis hloov. Txawm hais tias AlNiCo hlau nplaum, sintered Samarium Cobalt hlau nplaum, thiab sintered Neodymium hlau nplaum tau siv nyob rau hauv geophones, nrum AlNiCo hlau nplaum tseem suav hais tias yog qhov kev xaiv zoo tshaj plaws ntawm geophone hlau nplaum vim lawv qhov raug siab, ruaj khov, thiab tus nqi qis. Nws yuav tsum tau muab sau tseg tias cov hlau nplaum no muaj ib tug nruj heev dimension kam rau ua.
