FC-S60S Lub Rooj Sib Txuas Uas Tiv Thaiv Kub Siab
Cov tshuaj ntxiv rau qhov sib nrug, uas tuaj yeem tshem tawm cov kua dej drilling tau zoo, tuaj yeem tiv thaiv cov cement slurry kom tsis txhob sib xyaw nrog nws. Muaj cov nyhuv ua rau cov cement slurry tuab nyob rau hauv qee qhov xwm txheej, yog li ntawd, yuav tsum siv cov tshuaj lom neeg inert spacing agents kom raug kom cais tawm ntawm cov cement slurry. Dej tshiab lossis dej sib tov tuaj yeem siv ua cov tshuaj lom neeg inert spacing agents.
• FC-S60S yog ib lub spacer uas tiv taus kub heev, uas yog sib xyaw los ntawm ntau yam polymers uas tiv taus kub.
• FC-S60S muaj zog thiab sib haum zoo. Nws tuaj yeem cais cov kua drilling thiab cov cement slurry thaum hloov cov kua drilling, thiab tiv thaiv kev tsim cov slurry sib xyaw ntawm cov kua drilling thiab cov cement slurry.
• FC-S60S muaj ntau qhov hnyav (txij li 1.0g/cm2)3txog 2.2g/cm33). Qhov sib txawv ntawm qhov ceev sab saud thiab qis dua yog lees dua 0.10g / cm3tom qab lub spacer tseem nyob li 24 teev.
Lub spacer tau npaj nrog cov yam ntxwv tshwj xeeb ntawm cov kua, xws li viscosity thiab density, uas tau tsim los hloov cov kua drilling thaum ua kom muaj kev tso cov cement sheath tiav. FC-S60S yog cov ntaub ntawv muaj nqis ntxiv uas yog tsom mus rau cov neeg siv khoom thiab kev daws teeb meem, hwm txhua yam kev qhia tshwj xeeb, cov cai ib puag ncig thiab cov qauv kev lees paub zoo tshaj plaws.
| Khoom | Cov Ntawv Qhia |

Ib lub spacer yog ib yam kua siv los cais cov kua drilling thiab cov slurries cementing. Ib lub spacer tuaj yeem tsim los siv nrog cov kua drilling uas yog dej lossis roj, thiab npaj ob qho tib si yeeb nkab thiab kev tsim rau kev ua haujlwm cementing. Cov spacers feem ntau yog densified nrog cov neeg sawv cev uas tsis yaj-khoom hnyav. Muaj cov nyhuv ua rau cov cement slurry tuab nyob rau hauv qee qhov xwm txheej, yog li ntawd, yuav tsum tau siv cov tshuaj inert spacing agents kom raug kom cais tawm ntawm cov cement slurry.
