FC-651S Cov Tshuaj Ntxiv Rau Kev Tswj Xyuas Kev Poob Dej Kub Siab
• FC-651S muaj kev hloov pauv zoo thiab siv tau rau ntau yam kev siv cement slurry. Nws muaj kev sib raug zoo nrog lwm cov tshuaj ntxiv. Raws li FC-650S, cov khoom tau txhim kho nws txoj kev tiv thaiv ntsev thiab muaj kev ua haujlwm tiv thaiv ntsev zoo dua.
• FC-651S yog tsim rau qhov kub thiab txias dav dav nrog kev tiv taus kub siab txog li 230 ℃. Qhov ruaj khov ntawm cov cement slurry system hauv qhov chaw kub siab zoo dua vim yog kev qhia HA.
• FC-651S siv tau ib leeg xwb. Qhov txiaj ntsig zoo dua thaum siv ua ke nrog FC-631S/ FC-632S.
• Nws tsim nyog rau kev npaj cov dej tshiab/dej ntsev.
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-651S yog cov tshuaj tswj kev poob kua dej kub siab thiab nws tsim nyog rau kev lag luam Canadian.

Cov tshuaj tswj kev poob kua tau ntxiv rau hauv cov roj av cement slurries rau ntau tshaj 20 xyoo, thiab kev lag luam cementing niaj hnub no lees paub tias qhov zoo ntawm cov haujlwm cementing tau zoo dua. Qhov tseeb, nws tau lees paub dav dav tias kev tswj hwm kev poob kua tsis raug yuav ua rau muaj kev ua tsis tiav ntawm cov cementing thawj zaug los ntawm kev nce ntau dhau ntawm qhov ceev lossis annulus bridging, thiab tias cement filtrate nkag mus rau hauv qhov tsim yuav ua rau muaj kev phom sij rau kev tsim khoom. Cov tshuaj ntxiv rau kev poob kua tuaj yeem ua rau kev rov qab zoo dua los ntawm kev tiv thaiv cov roj thiab cov roj txheej kev ua qias tuaj ntawm cov kua lim ntxiv rau kev tswj hwm kev poob kua ntawm cov cement slurry.
