FC-633S Cov Tshuaj Ntxiv Rau Kev Tswj Xyuas Kev Poob Dej Kub Siab
• FC-633S muaj viscosity siab ntawm qhov nrawm qis, uas tuaj yeem txhim kho qhov ruaj khov ntawm lub kaw lus cement slurry, tswj qhov fluidity ntawm slurry, tiv thaiv kev sedimentation tib lub sijhawm, nws muaj kev ua tau zoo tiv thaiv ntsev, tab sis nws tsis muaj kev ua haujlwm tiv thaiv roj channeling vim yog kev hloov pauv ntawm pawg ua haujlwm.
• FC-633S muaj kev hloov pauv zoo thiab siv tau rau ntau yam kev siv cement slurry. Nws muaj kev sib raug zoo nrog lwm cov khoom ntxiv.
• FC-633S siv tau rau qhov kub thiab txias dav dav thiab tiv taus kub txog li 230 ℃. Tom qab siv, cov kua ntawm cov cement slurry system zoo, ruaj khov nrog cov kua tsawg dua thiab tsis muaj kev ncua thiab lub zog thaum ntxov ntawm qhov kub qis sai sai. Nws siv tau rau kev npaj cov dej tshiab/dej ntsev slurry.
Cov chaw roj kub siab ntsib ntau yam teeb meem tshwj xeeb thaum nws los txog rau kev sib xyaw ua ke qhov dej. Ib qho ntawm cov teeb meem no yog qhov teeb meem ntawm kev poob kua, uas tuaj yeem tshwm sim thaum cov av nkos lim dej nkag mus rau hauv qhov chaw thiab ua rau cov kua dej tsawg dua. Txhawm rau daws qhov teeb meem no, peb tau tsim cov khoom siv txo cov kua dej tshwj xeeb uas tau tsim tshwj xeeb rau kev siv hauv cov chaw roj kub siab. FC-633S yog cov tshuaj tswj kev poob kua dej kub siab thiab nws tsim nyog rau kev lag luam North American.

Cov tshuaj tswj kev poob kua tau raug qhia rau cov roj-qhov av cement slurries rau ntau tshaj 20 xyoo, thiab kev lag luam cementing tau pom tias muaj kev txhim kho zoo hauv qhov zoo ntawm cov haujlwm cementing. Qhov tseeb, nws tau lees paub zoo tias qhov tsis muaj kev tswj kev poob kua yuav yog qhov ua rau muaj kev ua tsis tiav ntawm cov cementing thawj zaug vim yog qhov ntom ntom ntau dhau lossis annulus bridging, thiab tias cement filtrate nkag mus rau hauv qhov tsim yuav ua rau muaj kev puas tsuaj rau cov zis. Cov tshuaj ntxiv rau kev poob kua tuaj yeem pab cov cement slurry rov qab zoo dua los ntawm kev tiv thaiv cov roj thiab cov roj txheej ua qias tuaj nrog rau kev tswj kev poob kua ntawm cov cement slurry.
