Izongezo zoLawulo loLahleko lwe-FC-631S
• I-FC-631S inokuguquguquka okuhle kwaye ingasetyenziswa kwiinkqubo ezahlukeneyo zesamente. Ihambelana kakuhle nezinye izongezo.
• I-FC-631S inoburhabaxa obuphezulu obunesantya esiphantsi sokucheba, nto leyo enokuphucula ngokufanelekileyo uzinzo lokumiswa kwenkqubo yokulunywa kwesamente, igcine ukutyibilika kolurhabaxa, ithintele ukubola kwangaxeshanye, kwaye ibe nokusebenza kakuhle kokulwa nokutsha kwegesi.
• I-FC-631S ifanelekile kubushushu obubanzi obunokumelana nobushushu obuphezulu ukuya kuthi ga kwi-230℃. Emva kokusetyenziswa, ukunyibilika kwenkqubo yesamente slurry kulungile, izinzile ngolwelo olukhululekileyo oluncinci kwaye alunanto yakwenza nokulibaziseka kwaye amandla okuqala kubushushu obuphantsi akhula ngokukhawuleza.
• I-FC-631S ingasetyenziswa yodwa. Isiphumo siba ngcono xa isetyenziswa kunye ne-FC-650S.
• I-FC-631S ifanelekile ekulungiseleleni uthuli lwamanzi amatsha.
Iintsimi yeoyile ezinobushushu obuphezulu zijongene nemingeni eyahlukileyo xa kufikwa ekuqinisweni kwemithombo. Enye yezi mingeni yingxaki yokulahleka kolwelo, enokwenzeka xa i-filtrate yodaka lokugrumba ingena ekwakhekeni kwayo kwaye ibangele ukwehla komthamo wolwelo. Ukusombulula le ngxaki, siye saphuhlisa isixhobo sokunciphisa ukulahleka kolwelo esikhethekileyo esenzelwe ngokukodwa ukusetyenziswa kwiintsimi yeoyile ezinobushushu obuphezulu. I-FC-631S luhlobo lolawulo lokongeza ukulahleka kolwelo kwaye ifanelekile kwimarike yaseRashiya naseMntla Melika.

Kangangeminyaka engaphezu kwama-20, izinto zokulawula ukulahleka kolwelo zongezwe kwi-oil-source cement slurry kwaye ngoku kuyaziwa kwishishini ukuba umgangatho wemisebenzi yokufaka i-cement uphucuke kakhulu. Enyanisweni, ngokubanzi kuyavunywa ngokucacileyo ukuba ukungabikho kolawulo lokulahleka kolwelo kunokubangela ukusilela kokuqala kwe-cement, ngenxa yokwanda koxinano okanye i-annulus bridging kwaye ukuhlaselwa kokwakheka yi-cement filtrate kunokuba yingozi kwimveliso. I-fluid loss additive ayinakulawula kuphela ukulahleka kolwelo lwe-cement slurry, kodwa ikwathintela umaleko we-oyile negesi ekubeni ungcoliswe lulwelo oluhluziweyo kwaye ngaloo ndlela yonyusa ukusebenza kakuhle kokubuyisela.
