Borehole Imaging Maps Khoom

Borehole Imaging Maps Khoom

Borehole imaging maps khoom piav qhia tag nrho cov ntau hom qhov drilled raws li ib feem ntawm qhov kev tshawb xyuas geotechnical los yog ib puag ncig ntawm qhov kev ntsuam xyuas los ntawm kev sau cov ntsiab lus ntawm qhov drilling nyob rau hauv txoj kev duab thiab video.

Ntsiab Cai:

Tus ciaj ciam teleperer nrog lub tshuab pulsed acoustic lub zog kom nws tuaj yeem pom cov phab ntsa borehole nyob rau hauv lub xub ntiag opaque drilling muds. Luv tawg ntho ntawm lub zog acoustic yog tawm los ntawm ib qho kev hloov transducer rau hom mem tes-ncha. Cov kev taug kev los ntawm cov av nkos thiab ua tiav ib feem ntawm cov phab ntsa borehole. Reflected pulses tau txais los ntawm lub transducer. Lub amplitudes ntawm cov reflected pulses ua lub hauv paus ntawm acoustic duab ntawm phab ntsa borehole. Cov amplitudes yog tswj los ntawm ntau yam. Thawj yog cov duab ntawm lub phab ntsa borehau nws tus kheej: cov kev ua tsis ncaj ncees ua rau lub zog txav mus rau qhov chaw qis qis kom qis zog tau txais qhov teeb meem ntawm lub transducer. Piv txwv ntawm cov kev tsis sib haum xeeb no yog pob txha, vugs, thiab kev ua txhaum. Tshaj li, cov teeb meem ntawm lub suab seev yog degraded nyob rau hauv elliptical thiab qoob loo zoo nkauj vim tsis muaj xwm txheej tshwm sim. Qhov thib ob yam yog qhov sib txawv hauv cov acoustic impedance ntawm cov av nkos thiab cov khoom uas ua rau cov phab ntsa borehole. Acoustic impedance muab ib qho ntsuas acoustic ntawm tus txheeb ze ntawm cov formations nkag los ntawm cov khoom siv zoo thiab, yog li, nws muaj peev xwm cais ntawm kev sib txawv ntawm lithologies, nrog siab acoustic impedance muab nce mus siab siab reflected amplitudes. Borehole televiewers ua hauj lwm zoo tshaj plaws uas cov phab ntsa borehole yog tus zoo thiab qhov sib txawv hauv cov acoustic impedance siab. Qhov thib peb yog qhov tawg lossis nqus ntawm acoustic zog los ntawm cov khoom hauv qhov av nkos. Qhov teeb meem no loj dua hauv hnyav hnyav hnyav hnyav, uas yog qhov feem ntau yog acoustically, thiab nws muab nce mus rau ib qho poob ntawm daim duab daws teeb meem.


Tus borehole televiewer yuav muab tau 360 degree duab rau hauv qhov qhib lossis khawm qhov. Nws tuaj yeem khiav lag luam nyob rau hauv txhua qhov chaw hauv cov cheeb tsam uas tsis yog qhov muaj qhov ua qhov roj. Lub sij hawm taug kev mus rau lub suab paj nruag acoustic nyob ntawm qhov kev sib nraus ntawm qhov kev hloov thiab cov phab ntsa borehole, nrog rau cov av tshaj tawm. Cov neeg tho niaj hnub pub qee txoj kev ywj pheej ntawm kev ntsuas av nkos. Yog li, tus borehole televiewer tseem ua haujlwm raws li tus txheej txheem ntawm caliper acoustic. Rau qhov zoo tshaj plaws, lub cuab tam yuav tsum tau koom, txawm hais tias kho cov algorithms tau tsim rau eccentered kuaj.



Daim ntawv thov:

Nws yog tsim rau tej yam xws li engineering xws li engineering geology, hydrological geology, geotechnical engineering soj ntsuam thiab xyuas. Nws yog tsim rau ntau cov boreholes nrog rau ntsug borehole, kab rov tav borehole, thauj tog rau nkoj (pas nrig) lub qhov dej, cov roj hmab thiab cov pob zeb borehole. Nws tuaj yeem tsim cov qauv hauv cov tub ntxhais cov qauv siv rau kev txuag txiav, tshwj xeeb tshaj yog rau cov crushing tsam strata qhov twg tsis tuaj yeem tau txais cov tub ntxhais kuaj. 1.Xav tagnrho-qhov duab phab ntsa thiab video teev rau ntawm qhov tseemceeb ntawm lub hauv paus, khaws cov duab ntawm qhov tseem ceeb, thiab lwm yam.

2. Soj ntsuam thiab ntsuas qhov thickness thiab orientation ntawm interlayer hauv pawg;

3. Soj ntsuam thiab ntsuas qhov tob ntawm txoj hauj lwm thiab qhov puas ntawm tawg pawg Qhov dav ntawm qhov kev taw qhia.



Tseem ceeb nta:

1. Muaj kev sib koom siab: kev sib xyaw ua ke tswj, duab tshaaj, tso saib thiab cia hauv kev tswj;

Tib lub sijhawm, cov ntaub ntawv duab, cov ntaub ntawv qhia tob thiab cov ntaub ntawv ntawm qhov chaw ntawm qhov kev sojntsuam tau muab, uas muaj peev xwm xyuas kom tseeb tias lub sijhawm pib ntawm qhov pib duab panoramic, yoojyim thiab seamless splicing, tsis siv neeg lub qhov tob thiab qhov tob, thiab panoramic duab duab yog nthuav tawm nyob rau ntawm lub sijhawm, thiab cov duab yog meej thiab tseeb. Synchronize cov duab stitching, cov ntaub ntawv thiab cov screenshots;

3. Kev muaj kev ruaj siab: Tag nrho lub cev muaj kev sib raug zoo thiab muaj kev ruaj ntseg zoo; qhov ntsuas yog ntim, dej tsis muaj dej thiab tsis muaj hmoov av;

4. Cov lus txhais tau zoo: Lub koob yees duab yog xim tsis muaj teeb pom kev zoo 700Lines, 0.1L1.x, 1.3 lab pixels; qhov kev siv ntawm lub teeb qhov chaw tuaj yeem hloov kho kom pom tseeb ntawm cov duab pom ntau yam;

5. Voj pom lub kaum sab xis: Lub koob yees duab muaj ib lub dav muag dav, uas muaj peev xwm paub txog tav toj siab 360-degree panoramic imaging tsis tsom;

6. Kev txav chaw zoo: Lub tshuab tseem tsawg me me, qhov loj hauv qhov hnyav thiab yooj yim heev;

7. Kev ua haujlwm zoo: Lub kaw lus tseem ceeb yooj yim mus txuas, yooj yim rau kev lag luam, thiab thawj zaug siv neeg siv tau pib ua sai sai; tus tswv tsev yuav siv tau ua lwm lub USB flash drive ntawm lub computer, thiab cov ntaub ntawv tuaj yeem muab theej thiab luam tau;

8. Cov kev cai tsis tshua muaj zog: Tus tswv tsev tau ua kom muaj teeb meem lithium roj teeb, thiab lub sijhawm ua haujlwm tsis tu ncua tsis tshaj 10 teev;

9. Peb hom zaub yooj ywm hloov: kev soj ntsuam software tuaj yeem tso tawm thiab tso zis rau daim ntawv qhia dav hlau dav, lub stereoscopic histogram, stereoscopic histogram tuaj yeem tig tau 360 degree tsis tu ncua; cov ntsiab lus tseem ceeb tshwm sim los ntawm lub rooj thiab cov cim histogram thiab daim ntawv qhia nthuav dav kuj tuaj yeem tshwm rau tib qhov dav;

10. Cov kev qhia ncaj qha: Lub hauv paus qhia ncaj ncaj tau piav txog daim ntawv qhia tsis muaj tseeb. Lub inclination, inclination thiab dav ntawm lub keej tau ncaj qha xam thiab rho tawm tau. Qhov dav dav yuav ncav cuag 0.1 hli thiab lub azimuth kaum tau ncav cuag 0.1 degree.
