FC-FR180S Fluid tsis tswj
Cov kua dej poob tswj sulphonate copolymer (drilling fluid) FC-FR180S yog tsim los ntawm ntau cov kauj ruam polymerization nyob rau hauv qhov kev txiav txim los ntawm acrylic amide, acrylic acid, 2-acryloyloxybutyl sulfonic acid (AOBS), epoxy chloropropane thiab tshiab nplhaib qauv cationic monomer.Cov khoom no yog ib tug dav-spectrum kub resistant thiab ntsev resistant kua tsis tswj nrog zoo heev kua poob kev ua tau zoo.Nws muaj qhov zoo viscosity nce cov txiaj ntsig hauv cov dej tshiab slurry, thiab me ntsis nce viscosity hauv cov dej ntsev slurry thiab tuaj yeem siv los ua tus neeg sawv cev rau viscosity nce thiab kua poob tswj hauv cov khoom dawb thiab tsis tshua muaj cov dej drilling.Cov khoom no muaj qhov kub thiab txias tsis kam thiab ntsev, qhov kub thiab txias tuaj yeem ncav cuag 180 ℃, thiab ntsev kuj tuaj yeem ncav cuag saturation.Nws yog tshwj xeeb tshaj yog haum rau seawater drilling kua, sib sib zog nqus zoo drilling kua thiab ultra tob zoo drilling kua.

1. Cov nyhuv siab, tsawg npaum li cas, kev ua haujlwm zoo ntawm kev tswj tsis tau dej.
2. Nws muaj qhov zoo thermal stability thiab kub tsis kam ntawm 180 ℃, thiab tuaj yeem siv rau hauv qhov dej tob thiab ultra tob;
3. Nws muaj zog ntsev tsis kam rau saturation thiab calcium magnesium tsis kam, thiab tuaj yeem siv rau drilling thiab ua tiav cov kua dej hauv cov dej tshiab, dej ntsev, dej qab ntsev thiab dej hiav txwv;
4. Nws muaj qhov zoo viscosity nce cov nyhuv hauv cov dej tshiab slurry.
