Mhedzisiro yeHydroxyethyl Cellulose muOilfields

Hydroxyethyl Cellulose (HEC) ipolymer inonyungudika mumvura iyo inowanzoshandiswa muindasitiri yemafuta negasi se rheology modifier, thickener, uye stabilizer. Heano mamwe emhedzisiro yeHEC muminda yemafuta:

1. Viscosity control: HEC inoshandiswa kudzora viscosity yekuchera zvinwiwa uye simende slurries muminda yemafuta. Inobatsira kuchengetedza viscosity yakagadzikana pasi pemamiriro akasiyana-siyana, akadai sekushisa uye kuchinja kwekumanikidza.
2. Filtration control: HEC inogona kuderedza chiyero chekurasikirwa kwemvura mumvura yekuchera uye simende slurries, iyo inovandudza yavo yekusefa yekudzora zvivakwa. Izvi zvinobatsira kudzivirira kugadzirwa kwemakeke edhaka asingapindike uye kuderedza njodzi yekunamira pombi panguva yekuchera.
3. Shear kuonda: HEC inoratidza shear-kuonda maitiro, izvo zvinoreva kuti viscosity yayo inoderera pasi pekuveura kushushikana. Ichi chivakwa chinogona kubatsira mune oirifield application uko yakaderera viscosity inodiwa panguva yekupomba asi yakakwirira viscosity inodiwa mutsime.
4. Fluid kugadzikana: HEC inobatsira kudzikamisa mvura yekuchera uye simende slurry nekudzivirira kugadzirisa uye flocculation yezvakarembera zvakasimbiswa.
5. Kuenderana kwezvakatipoteredza: HEC ine hushamwari kwezvakatipoteredza uye haikonzerese kukuvadza kune ecosystem. Haina-chepfu uye inoora, zvichiita kuti ive sarudzo yakachengeteka yekushandisa muminda yemafuta.
6. Kuenderana nezvimwe zvinowedzera: HEC inowirirana nehuwandu hwakawanda hwezvimwe zvinowedzera zvinoshandiswa muindasitiri yemafuta uye gasi, kusanganisira kuchera madhaka, brines, uye simende slurries. Inogona kushandiswa pamwe chete nemamwe mapolymers, akadai se xanthan gum, kuvandudza kushanda kwemvura yekuchera uye simenti slurries.

Pakazere, mhedzisiro yeHEC muminda yemafuta inoita kuti ive yekuwedzera yakakosha yekusimudzira zvimiro zvekuchera zvinwiwa uye simende slurries. Iyo viscosity control, filtration control, shear kuonda maitiro, kugadzikana kwemvura, kuenderana kwezvakatipoteredza, uye kuenderana nezvimwe zvinowedzera zvinoita kuti ive chinhu chakakosha muindasitiri yemafuta negesi.
