1. Hydroxyethyl cellulose hmoov tuaj yeem tawm hauv dej kub thiab dej txias, thiab yuav tsis nag lossis daus los yog hau. Vim tias, nws muaj ntau yam ntawm solubility thiab viscosity tus yam ntxwv thiab tsis yog - thermogelability.
2. Hec tuaj yeem lis cov dej nrog lwm cov dej - soluble polymers, surfactants, thiab ntsev. HEC yog qhov zoo tshaj plaws colloidal tuab muaj cov kev daws teeb meem dientectrtric.

4. Piv rau methylcellulose thiab hydroxyprropyilcethylcelylulose, HEC muaj cov muaj zog tiv thaiv kev tiv thaiv muaj zog.
Kev lag luam kev tsim kho: Hec tuaj yeem siv los ua cov dej noo returent tus neeg saib xyuas thiab cov chaw ua haujlwm xis nyob rau hauv inhibitor.
Roj Drilling Kev Lag Luam: Nws tuaj yeem siv los ua tuab thiab tus neeg sawv cev rau cov roj ua kua. Cov dej lim dej nrog HEC tuaj yeem txhim kho kev ruaj khov drilling ruaj khov raws nws cov khoom muaj zog qis muaj nuj nqi.
Txheej kev lag luam: HEC tuaj yeem ua lub luag haujlwm hauv thickening, dispersify, dispersing, ruaj khov thiab khaws dej rau cov ntaub ntawv yas. Nws yog tus cwj pwm los ntawm cov nyhuv tuab tuab tuab, xim zoo ri tau, zaj duab xis tsim, thiab kev ruaj khov.
Daim ntawv thiab cwj mem: Nws tuaj yeem siv ua tus sawv cev ntawm cov ntawv thiab cov ntawv nyeem, ua cov neeg sawv cev thiab ncua rau dej.
Tshuaj Txhua Hnub: HEC yog kev ua yeeb yaj kiab zoo - kev ua yeeb yaj kiab, nplaum, cov nplaum thiab cov khoom siv cov plaub hau, thiab tshuaj pleev ib ce.
