FC-600S Cov tshuaj ntxiv rau kev tswj cov kua dej poob
Muaj ob hom kev ua ub ua no tseem ceeb hauv kev ua cementing, uas yog, kev ua cementing thawj zaug thiab kev ua cementing thib ob. Kev ua cementing thawj zaug kho cov hlau casing rau ntawm cov formation ib puag ncig. Kev ua cementing thib ob yog siv rau kev sau cov formations, sealing, lossis kaw dej. Cov tshuaj ntxiv rau kev poob kua, uas ruaj khov rau qhov kub siab thiab cov ntsev concentrated, ua kom ntseeg tau tias muaj kev ua haujlwm cementing txhim khu kev qha hauv qab cov xwm txheej nyuaj.
• FC-600S yog cov tshuaj polymer uas ua rau cov kua dej poob rau cov cement siv rau hauv cov roj qhov thiab tsim los ntawm kev sib xyaw nrog AMPS ua cov monomer tseem ceeb nrog kev tiv taus kub thiab ntsev zoo thiab ua ke nrog lwm cov monomers tiv thaiv ntsev. Cov molecule muaj ntau pawg adsorptive xws li - CONH2, - SO3H, - COOH, uas ua lub luag haujlwm tseem ceeb hauv kev tiv taus ntsev, tiv taus kub, nqus dej dawb, txo dej poob, thiab lwm yam.
• FC-600S 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-600S yog tsim rau qhov kub thiab txias dav dav nrog kev tiv taus kub siab txog li 180 ℃. Tom qab siv, qhov fluidity ntawm cov cement slurry system zoo, ruaj khov nrog tsawg dua cov kua dawb thiab tsis muaj kev ncua kev teeb tsa thiab lub zog tsim sai.
• FC-600S yog tsim rau kev npaj cov dej tshiab/dej ntsev.

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.
Q1 Koj cov khoom tseem ceeb yog dab tsi?
Peb feem ntau tsim cov roj zoo cementing thiab drilling additives, xws li kua poob tswj, retarder, dispersant, anti-gas migration, deformer, spacer, flushing kua thiab lwm yam.
Q2 Koj puas tuaj yeem muab cov qauv?
Yog, peb tuaj yeem muab cov qauv dawb.
Q3 Koj puas tuaj yeem kho cov khoom?
Yog, peb tuaj yeem muab cov khoom rau koj raws li koj xav tau.
Q4 Koj cov neeg siv khoom tseem ceeb yog los ntawm lub teb chaws twg?
North America, Asia, Tebchaws Europe thiab lwm thaj chaw.
