Hydroxyethyl Cellulose HEC Rau Kev Siv Roj

Hydroxyethyl Cellulose (HEC) yog ib qho nonionic, ceev hydrating, thiab ultra-siab viscosity.HEC yog siv los ua viscosity thiab rheology modifier, dej tuav tus neeg saib xyuas, stabilizer, thiab suspending tus neeg sawv cev nyob rau hauv ib tug ntau yam ntawm cov dej-raws li lub tshuab uas xav tau ib yam khoom nonionic.

Siv rau hauv cementing thiab roj drilling kev lag luam:

Drilling av (khoom khib nyiab thiab brine kua)

Drill-in-kua

Spud av nkos (tam sim no viscosity)

Ua kom tiav thiab ua haujlwm kua dej (Brine kua)

Pob zeb pob zeb

Spacers los yog flushes

Txiav kev txhaj tshuaj

Fracturing fluids (raug tshem tawm ntawm cov khoom siv)

Hydroxyethyl Cellulose thickening tus neeg sawv cev tuaj yeem siv los ua cov roj ua haujlwm ua kua thiab cementing tus neeg sawv cev.Pab muab kev qhia meej txog cov ntsiab lus tsis tshua muaj kev ruaj ntseg, yog li txo qis cov qauv kev puas tsuaj rau cov qhov dej.Kev siv Hydroxyethyl Cellulose thickening kua tau yooj yim acids, enzymes los yog oxidants decomposition, zoo heev txhim kho lub peev xwm rov qab hydrocarbons.

Cov kua dej hauv lub qhov dej, Hydroxyethyl Cellulose yog siv los ua cov cab kuj.Cov kua dej no tuaj yeem yooj yim los ntawm cov txheej txheem tawg

Hydroxyethyl Cellulose configuration siv cov kua dej drilling, raws li nws cov ntsiab lus tsis tshua muaj, tuaj yeem ua kom muaj kev ruaj ntseg drilling.Cov khoom no tuaj yeem siv los cuam tshuam cov kua nruab nrab mus rau siab hardness ntawm pob zeb thiab hnyav shale lossis shale drilling

Kev txhawb zog hauv kev ua haujlwm cement, Hydroxyethyl Cellulose slurry tuaj yeem txo qhov kev sib txhuam hydraulic, qhov poob ntawm pob zeb kom txo qis dej.
