FC-631S Cov Tshuaj Ntxiv rau Kev Tswj Xyuas Kev Poob Kua
• FC-631S 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-631S muaj viscosity siab thiab shear rate qis, uas tuaj yeem txhim kho qhov ruaj khov ntawm cov cement slurry system, tswj qhov fluidity ntawm slurry, tiv thaiv kev sedimentation tib lub sijhawm, thiab muaj kev ua haujlwm zoo tiv thaiv roj channeling.
• FC-631S yog tsim rau qhov kub thiab txias dav dav nrog kev tiv taus kub siab txog li 230 ℃. Tom qab siv, qhov fluidity ntawm cov cement slurry system zoo, ruaj khov nrog tsawg dua cov kua dawb thiab tsis muaj retarding teeb tsa thiab lub zog thaum ntxov ntawm qhov kub qis tsim sai.
• FC-631S siv tau ib leeg xwb. Qhov zoo dua thaum siv ua ke nrog FC-650S.
• FC-631S yog tsim rau kev npaj cov dej tshiab.
Cov chaw roj kub siab ntsib ntau yam teeb meem tshwj xeeb thaum nws los txog rau kev ua kom lub qhov dej zoo. 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-631S yog ib hom kev tswj cov kua dej poob thiab nws tsim nyog rau kev lag luam Lavxias thiab North American.

Tau ntau tshaj 20 xyoo, cov tshuaj tswj kev poob kua tau ntxiv rau hauv cov roj av cement slurries thiab tam sim no nws tau lees paub hauv kev lag luam tias qhov zoo ntawm cov haujlwm cementing tau zoo dua qub. Tseeb tiag, nws feem ntau lees paub meej tias tsis muaj kev tswj kev poob kua yuav yog lub luag haujlwm rau kev ua tsis tiav ntawm cov cementing thawj zaug, vim yog qhov ntom ntom ntau dhau lossis annulus bridging thiab tias kev tsim los ntawm cement filtrate tuaj yeem ua rau muaj kev phom sij rau kev tsim khoom. Cov tshuaj ntxiv rau kev poob kua tsis tsuas yog tuaj yeem tswj tau qhov poob kua ntawm cov cement slurry, tab sis kuj tiv thaiv cov roj thiab cov roj txheej kom tsis txhob raug kuab paug los ntawm cov kua lim thiab yog li ua rau kom muaj kev rov zoo dua.
