Mhedzisiro yeHydroxyethyl Cellulose muOilfields

Hydroxyethyl cellulose (HEC) inowana akati wandei mashandisirwo muindasitiri yeoiri negasi, kunyanya muminda yemafuta. Heano mamwe emhedzisiro uye mashandisiro eHEC mukuita oirifield mashandiro:

1. Drilling Fluids: HEC inowanzowedzerwa kumvura yekuchera kudzora viscosity uye rheology. Inoshanda se viscosifier, inopa kugadzikana uye kuwedzera simba rekutakura remvura yekuchera. Izvi zvinobatsira kumisa kuchekwa kwezviboorwa nezvimwe zvionda, zvichidzivirira kugadzika uye kukonzera kuvharika mutsime.
2. Yakarasika Yekutenderera Kudzora: HEC inogona kubatsira kudzora yakarasika kutenderera panguva yekuchera mabasa nekugadzira chipingamupinyi kurwisa kurasikirwa kwemvura kuita porous mafomu. Inobatsira kuvhara kuputsika uye dzimwe nzvimbo dzinopindirana mukugadzirwa, kuderedza njodzi yekurasikirwa kwekutenderera uye kusagadzikana kwematsime.
3. Wellbore Kucheneswa: HEC inogona kushandiswa sechikamu mutsime rekuchenesa mvura kubvisa marara, madhaka ekuchera, uye keke rekusefa kubva mutsime nekuumbwa. Viscosity yayo uye kumiswa zvivakwa zvinobatsira mukutakura zvimedu zvakasimba uye kuchengetedza kufamba kwemvura panguva yekuchenesa mabasa.
4. Enhanced Oil Recovery (EOR): Mune dzimwe nzira dzeEOR dzakadai semafashama epolymer, HEC inogona kushandiswa seyakakora mumiriri wekuwedzera viscosity yemvura kana mapolymer solutions akaiswa mudziva. Izvi zvinovandudza kutsvaira, zvinobvisa mamwe mafuta, uye zvinowedzera kudzoreredza mafuta kubva mudura.
5. Fluid Kurasika Kudzora: HEC inoshanda mukudzora kurasikirwa kwemvura mune simende slurries inoshandiswa mukusimbisa mashandiro. Nekugadzira keke rakatetepa, risingapindiki refirita pachiso chechimiro, rinobatsira kudzivirira kurasikirwa kwemvura yakawandisa kusvika pakuumbwa, kuve nechokwadi chekuzviparadzanisa nevamwe uye kutendeseka zvakanaka.
6. Fracturing Fluids: HEC inoshandiswa mu hydraulic fracturing fluid kupa viscosity uye fluid-kurasikirwa kwekudzora. Inobatsira kutakura mapropants mumafractures uye kuchengetedza kumiswa kwavo, kuve nechokwadi chekushanda kwekutsemuka uye kupora kwemvura panguva yekugadzira.
7. Zvakanaka Kukurudzira: HEC inogona kuiswa mumvura ine acidizing uye mamwe matsime ekusimudzira marapirwo ekuvandudza fluid rheology, kudzora kurasikirwa kwemvura, uye kuwedzera kuenderana kwemvura nemamiriro ekuchengetedza. Izvi zvinobatsira kukwidziridza mashandiro ekurapa uye kuwedzera kugadzirwa kwakanaka.
8. Kupedzisa Fluids: HEC inogona kuwedzerwa pakupedzisa zvinwiwa kugadzirisa viscosity yavo uye kumiswa zvivakwa, kuve nechokwadi chekushanda kwematombo ematombo, kutonga kwejecha, uye kucheneswa kwegomba panguva yekupedza mabasa.

Hydroxyethyl cellulose (HEC) inobata basa rakakosha mumashandisirwo akasiyana-siyana emumunda wemafuta, ichibatsira mukuchera, kugadzikana kwetsime, manejimendi ekuchengetedza, uye kugadzirisa kugadzirwa. Kushanda kwakasiyana-siyana, kushanda, uye kuenderana nezvimwe zvinowedzera zvinoita kuti ive chinhu chakakosha muoirifield fluid masisitimu uye marapirwo.
