Daim ntawv thov ntawm Hydroxyethyl Cellulose hauv Oilfield Drilling

Hydroxyethyl cellulose (HEC) yog cov dej-soluble polymer uas tau siv dav hauv kev lag luam roj thiab roj, tshwj xeeb hauv kev ua haujlwm drilling.HEC yog siv rau hauv cov kua dej drilling los muab kev tswj xyuas rheological thiab kev tiv thaiv kev poob dej.Cov hauv qab no yog qee qhov kev thov tshwj xeeb ntawm HEC hauv cov roj av drilling:

1. Rheology Control: HEC yog siv los tswj cov rheology ntawm drilling kua.Qhov sib ntxiv ntawm HEC ua rau kom cov viscosity ntawm cov dej drilling, uas yuav pab kom tshem tawm cov laum txiav thiab tiv thaiv kev daws teeb meem.Lub viscosity ntawm cov kua drilling kuj tuaj yeem hloov kho los ntawm qhov sib txawv ntawm HEC hauv cov kua.
2. Fluid Poob Tiv Thaiv: HEC yog siv los ua cov kua dej poob ntxiv hauv cov kua dej drilling.Thaum ntxiv rau cov kua dej drilling, HEC tsim ib zaj duab xis nyias ntawm cov phab ntsa ntawm lub qhov dej, uas yuav pab tiv thaiv kom tsis txhob poob ntawm cov dej drilling rau hauv qhov tsim.
3. Suspension of Solids: HEC yog tus neeg sawv cev zoo rau cov khoom siv hauv cov dej drilling.Qhov sib ntxiv ntawm HEC pab ua kom cov khib nyiab hauv kev ncua, tiv thaiv lawv los ntawm kev nyob hauv qab ntawm qhov dej.
4. Lim Control: HEC yog siv los ua tus neeg saib xyuas kev pom hauv cov kua dej.Qhov sib ntxiv ntawm HEC pab tswj tus nqi ntawm cov dej drilling filtrates rau hauv kev tsim, tiv thaiv qhov poob ntawm cov dej muaj txiaj ntsig drilling.

Hauv cov ntsiab lus, Hydroxyethyl cellulose (HEC) plays lub luag haujlwm tseem ceeb hauv kev lag luam roj thiab roj raws li cov kua dej ntxiv, muab kev tswj xyuas rheological, kev tiv thaiv dej tsis zoo, tshem tawm cov khib nyiab, thiab kev tswj kom pom.
