FC-FR180S Kev tswj cov kua dej poob
Cov kua dej tswj kev poob sulphonate copolymer (drilling fluid) FC-FR180S yog tsim los ntawm ntau kauj ruam polymerization nyob rau hauv qhov kev ua ntawm initiator los ntawm acrylic amide, acrylic acid, 2-acryloyloxybutyl sulfonic acid (AOBS), epoxy chloropropane thiab lub nplhaib tshiab qauv cationic monomer. Cov khoom no yog ib qho dav-spectrum kub-resistant thiab ntsev-resistant kua tswj kev poob nrog zoo heev kua poob kev ua tau zoo. Nws muaj cov nyhuv zoo viscosity nce nyob rau hauv dej tshiab slurry, thiab me ntsis nce viscosity nyob rau hauv dej ntsev slurry thiab siv tau ua tus neeg sawv cev rau viscosity nce thiab kua poob kev tswj nyob rau hauv cov khoom khov dawb thiab cov khoom khov qis drilling kua. Cov khoom no muaj zoo kub-resistant thiab ntsev-resistant, kub-resistant tuaj yeem ncav cuag 180 ℃, thiab ntsev-resistant tuaj yeem ncav cuag saturation. Nws yog tshwj xeeb tshaj yog haum rau dej hiav txwv drilling kua, tob qhov dej drilling kua thiab ultra tob qhov dej drilling kua.

1. Cov nyhuv loj, tsawg koob tshuaj, ua haujlwm zoo ntawm kev tswj cov kua dej poob.
2. Nws muaj kev ruaj khov zoo thiab kub tsis kam ntawm 180 ℃, thiab tuaj yeem siv rau hauv qhov dej tob thiab tob heev;
3. Nws muaj zog tiv taus ntsev thiab tsis kam rau calcium magnesium, thiab siv tau rau kev khawb thiab ua tiav cov kua dej hauv dej tshiab, dej ntsev, dej ntsev thiab dej hiav txwv;
4. Nws muaj cov viscosity zoo ua rau cov dej tshiab muaj zog.
