Cenospheres hauv kev lag luam roj av

Ccov enospheres (kuj tseem muaj npe Cov Microspheres Hollow) yog ib yam khoom ntawm cov chaw tsim hluav taws xob hlawv thee thiab yog lub pob zeb tsis hnyav, tsis muaj zog, khoob uas muaj cua lossis roj tsis muaj zog. Cov xim ntawm Cenosphere txawv ntawm grey mus rau yuav luag dawb.
Cov khoom tshwj xeeb no (qhov ceev tsawg, lub zog siab, tshuaj lom neeg tsis muaj zog, tiv taus kub siab, zoo fluidity, thiab lwm yam) ua rau nws muaj ntau daim ntawv thov tseem ceeb hauv kev lag luam roj av, feem ntau yog hauv cov hauv qab no:

1. Cov cement slurry tsawg-density (cementing)

Cov Cenospheres (qhov ceev feem ntau yog 0.3-0.8 g / cm³) yog cov tshuaj ua kom lub teeb ci zoo heev. Thaum twg ntxiv rau cov cement slurry, lawv tuaj yeem txo qhov ceev ntawm cov cement slurry (mus rau 1.20 g / cm³ lossis qis dua). Lawv tuaj yeem tiv thaiv kev tawg ntawm cov qauv tsis muaj zog thiab txo qhov kev pheej hmoo ntawm kev xau. Piv nrog rau lwm cov neeg sawv cev ua kom pom tseeb (xws li bentonite, diatomaceous earth, thiab fly ash), Cenospheres tuaj yeem muab lub zog compressive siab dua ntawm qhov ceev qis dua. Cov microspheres pab txhim kho qhov fluidity thiab kev ua haujlwm ntawm cov cement slurry. Lawv pab tswj qhov ntau ntawm cov dej poob los ntawm cov cement slurry mus rau qhov tsim. Lub qauv hollow muab qee qib ntawm thermal rwb thaiv tsev, uas pab tiv thaiv kev poob siab thermal ntawm cov roj kub siab thiab cov roj txheej hauv cov qhov tob ntawm lub plhaub cement.

2. Cov kua dej drilling (av nplaum)

Zoo li daim ntawv thov hauv cov cement slurry, Cov Cenospheres tuaj yeem ntxiv rau cov kua dej los yog roj los ntawm kev khawb kom txo qhov ceev ntawm cov kua dej. Qhov no tseem ceeb heev rau kev khawb cov qauv siab qis, cov txheej xau loj heev, lossis thaum xav tau kev khawb tsis sib npaug (UBD). Nws tuaj yeem txo qhov siab ntawm qhov hauv qab, tiv thaiv kev xau, thiab tiv thaiv cov txheej tsim khoom. Qhov me me thiab cov qauv khov kho ntawm cov cenospheres ua rau nws yog cov khoom siv txuas zoo. Cov khoom me me pab txo cov yas viscosity thiab cov txiaj ntsig ntawm cov kua dej thiab txhim kho kev ua haujlwm. Nws cov khoom me me kuj tseem tuaj yeem txo qhov kev sib txhuam ntawm txoj hlua khawb thiab phab ntsa qhov dej, thiab ntawm txoj hlua khawb thiab lub plhaub.

3. Cov kav dej tiv thaiv xeb thiab rwb thaiv tsev thermal

Cov khoom siv rwb thaiv tsev thermal uas muaj cenospheres siv rau ntawm phab ntsa sab nraud ntawm cov kav dej roj los tsim ib txheej rwb thaiv tsev thermal tas mus li, uas tuaj yeem tiv thaiv kom tsis txhob muaj cua sov ntawm cov roj kub siab (lossis cov khoom siv kub qis) hauv cov kav dej kom tsis txhob poob rau hauv ib puag ncig sab nraud (lossis tiv thaiv kom tsis txhob muaj cua sov sab nraud xa mus rau cov kav dej kub qis), yog li tswj qhov kub ntawm cov khoom siv hauv cov kav dej kom ruaj khov, txo kev siv hluav taws xob.

ib. Txo qhov hnyavRau cov ntawv thov uas cov kav dej saum toj kawg nkaus lossis cov khoom siv yuav tsum tau txo qis, kev siv cov txheej rwb thaiv tsev cenospheres tuaj yeem txo qhov hnyav tag nrho ntawm cov kav dej.
b. Txhim kho kev ua haujlwm tau zooHauv cov ntaub ntawv cement, cov nyhuv spherical micro-bead ntawm cenospheres tuaj yeem ua lub luag haujlwm lubricating, txhim kho qhov fluidity thiab kev tsim kho ua haujlwm ntawm cov slurry, ua rau nws yooj yim dua rau twj, tsuag thiab thov, txo qhov kev tiv thaiv kev tsim kho, thiab tsim cov txheej txheem sib xws thiab ntom dua.
c. Txhim kho kev ua haujlwm tiv thaiv kev xeb ntawm cov txheej txheemLub ntsiab lus tseem ceeb ntawm cenospheres yog silicon txhuas iav, uas ruaj khov tshuaj lom neeg, tiv taus acid thiab alkali corrosion, thiab yuav tsis koom nrog cov tshuaj tiv thaiv corrosion, thiab tuaj yeem tswj kev ua tau zoo rau lub sijhawm ntev.

Lub kaw lus tiv thaiv xeb ua ke: Cov txheej txheej rwb thaiv tsev Cenospheres feem ntau yog siv ua ib feem ntawm tag nrho cov txheej txheem tiv thaiv xeb thiab rwb thaiv tsev kub. Cov txheej txheej Cenospheres feem ntau muab kev rwb thaiv tsev thiab txhim kho cov yam ntxwv ntawm lub cev.

Ntxiv rau cov ntawv thov tseem ceeb saum toj no, Cenospheres kuj muaj feem cuam tshuam tseem ceeb rau cov chaw ua roj hauv qab dej, cov khoom siv ntab, cov khoom siv ua kom av nkos ci ntsa iab, thiab lwm yam.
