Ob qho tib si bentonite thiab polymer slurries feem ntau yog siv cov ntaub ntawv nyob rau hauv ntau yam lag luam, tshwj xeeb tshaj yog nyob rau hauv drilling thiab kev tsim kho. Txawm hais tias muaj kev siv zoo sib xws, cov tshuaj no sib txawv hauv cov khoom xyaw, cov khoom thiab kev siv.
Bentonite:
Bentonite av nplaum, tseem hu ua montmorillonite av nplaum, yog cov khoom siv ntuj tsim los ntawm volcanic tshauv. Nws yog hom av nplaum-hom smectite yam ntxwv los ntawm nws cov khoom tshwj xeeb o thaum raug dej. Lub ntsiab ntawm bentonite yog cov ntxhia montmorillonite, uas muab nws cov khoom tshwj xeeb.
hauj lwm:
Bentonite av nplaum feem ntau yog tsim los ntawm montmorillonite thiab tseem muaj ntau yam ntawm lwm yam minerals xws li quartz, feldspar, gypsum, thiab calcite.
Cov qauv ntawm montmorillonite tso cai rau nws nqus dej thiab o, tsim cov khoom zoo li gel.
yam ntxwv:
o: Bentonite nthuav tawm qhov o tseem ceeb thaum hydrated, ua rau nws muaj txiaj ntsig zoo hauv kev sib khi thiab ntsaws daim ntaub ntawv.
Viscosity: Lub viscosity ntawm bentonite slurry yog siab dua, muab kev ncua zoo thiab txiav nqa peev xwm thaum drilling.
daim ntawv thov:
Drilling Fluids: Bentonite av nplaum feem ntau siv rau hauv cov av nkos rau cov roj thiab cov qhov dej. Nws pab txias thiab lubricate lub laum me ntsis thiab nqa cov chips rau saum npoo.
Sealing thiab Plugging: Bentonite cov khoom o tuaj yeem tso cai rau nws ua kom cov boreholes zoo thiab tiv thaiv cov dej tsiv teb tsaws.
qhov zoo:
Ntuj: Bentonite av nplaum yog ib txwm tshwm sim, ib puag ncig tus phooj ywg khoom.
Nqi-Effectiveness: Nws yog feem ntau tus nqi-zoo dua li lwm yam hluavtaws.
tsis txaus:
Tsawg qhov kub thiab txias: Bentonite tuaj yeem poob nws cov txiaj ntsig ntawm qhov kub thiab txias, txwv tsis pub siv hauv qee yam kev siv.
Kev daws teeb meem: Lub siab viscosity ntawm bentonite slurry tuaj yeem ua teeb meem yog tias tsis tswj xyuas kom zoo.
Polymer slurry:
Polymer slurries yog cov khoom sib xyaw ntawm cov dej thiab cov khoom siv hluavtaws tsim los ua kom tiav cov yam ntxwv ua tau zoo. Cov polymers no tau raug xaiv rau lawv lub peev xwm los txhim kho cov khoom ntawm slurry rau cov kev siv tshwj xeeb.
hauj lwm:
Polymer slurries yog tsim los ntawm dej thiab ntau yam hluavtaws polymers xws li polyacrylamide, polyethylene oxide, thiab xanthan gum.
yam ntxwv:
Tsis o: Tsis zoo li bentonite, polymer slurry tsis o thaum raug dej. Lawv tuav viscosity yam tsis muaj kev hloov pauv loj hauv ntim.
Shear Thinning: Polymer slurries feem ntau nthuav tawm tus cwj pwm shear thinning, uas txhais tau hais tias lawv cov viscosity txo qis nyob rau hauv kev nyuaj siab shear, uas pab txhawb nqa thiab ncig.
daim ntawv thov:
Trenchless Technology: Polymer av nkos feem ntau siv rau hauv kab rov tav directional drilling (HDD) thiab lwm yam kev siv trenchless los muab kev ruaj ntseg zoo thiab txo kev sib txhuam.
Kev tsim kho: Lawv yog siv rau hauv cov phab ntsa diaphragm, cov phab ntsa slurry thiab lwm yam kev tsim kho uas cov kua viscosity thiab stability yog qhov tseem ceeb.
qhov zoo:
Temperature stability: Polymer slurries tuaj yeem tswj lawv cov khoom ntawm qhov kub thiab txias, ua rau lawv haum rau ntau yam kev siv.
Txhim kho lubrication: Lub lubricating zog ntawm polymer slurries pab txo hnav ntawm cov khoom siv drilling.
tsis txaus:
Tus nqi: Polymer slurry tuaj yeem kim dua li bentonite, nyob ntawm seb cov khoom siv polymer tshwj xeeb.
Environmental Impact: Qee cov polymers hluavtaws tuaj yeem muaj kev cuam tshuam ib puag ncig uas yuav tsum tau ntsuas kev pov tseg kom tsim nyog.
nyob rau hauv xaus:
Thaum bentonite thiab polymer slurries muaj kev siv zoo sib xws thoob plaws hauv kev lag luam, lawv qhov sib txawv ntawm cov khoom xyaw, cov khoom thiab cov ntawv thov ua rau lawv haum rau cov xwm txheej sib txawv. Kev xaiv ntawm bentonite thiab polymer slurry nyob ntawm seb qhov yuav tsum tau ua ntawm ib qhov project, coj mus rau hauv tus account yam xws li tus nqi, kev cuam tshuam ib puag ncig, qhov kub thiab txias thiab cov yam ntxwv ntawm kev ua haujlwm. Cov kws tsim khoom thiab cov kws tshaj lij yuav tsum ua tib zoo tshuaj xyuas cov xwm txheej no los txiav txim siab cov ntaub ntawv zoo tshaj plaws rau lawv cov ntawv thov.
