Zotsatira za Hydroxyethyl Cellulose mu Oilfields

Hydroxyethyl cellulose (HEC) imapeza ntchito zingapo m'makampani amafuta ndi gasi, makamaka m'malo opangira mafuta.Nazi zina mwazotsatira ndikugwiritsa ntchito kwa HEC pantchito zamafuta:

1. Madzi Obowola: HEC nthawi zambiri imawonjezedwa kumadzi obowola kuti azitha kuwongolera kukhuthala ndi rheology.Zimagwira ntchito ngati viscosifier, zomwe zimapereka bata komanso kukulitsa mphamvu yonyamulira yamadzi obowola.Izi zimathandiza kuyimitsa zodulira ndi zolimba zina, kuti zisakhazikike ndikupangitsa kuti chitsime chitsekeke.
2. Kutaya Kuzungulira Kwamazungulira: HEC ikhoza kuthandizira kuwongolera kutayika kotayika panthawi yobowola popanga chotchinga chotchinga kutayika kwamadzimadzi kukhala ma porous mapangidwe.Imathandiza kusindikiza fractures ndi madera ena permeable mu mapangidwe, kuchepetsa chiwopsezo cha kutaya kufalitsidwa ndi bwino kusakhazikika.
3. Wellbore Cleanup: HEC itha kugwiritsidwa ntchito ngati chigawo chamadzi oyeretsera chitsime kuchotsa zinyalala, matope obowola, ndi keke yosefera kuchokera pachitsime ndi mapangidwe.Kukhuthala kwake komanso kuyimitsidwa kwake kumathandiza kunyamula tinthu tating'onoting'ono ndikusunga kuyenda kwamadzimadzi panthawi yoyeretsa.
4. Kubwezeretsanso Mafuta Owonjezera (EOR): Munjira zina za EOR monga kusefukira kwa polima, HEC itha kugwiritsidwa ntchito ngati chowonjezera kukulitsa kukhuthala kwamadzi kapena ma polima omwe amabayidwa m'madzi.Izi zimathandizira kusesa, kutulutsa mafuta ambiri, ndikuwonjezera kuchira kwamafuta kuchokera m'madzi.
5. Fluid Loss Control: HEC imagwira ntchito bwino pakuwongolera kutaya kwamadzi mu slurries ya simenti yomwe imagwiritsidwa ntchito popanga simenti.Popanga keke yopyapyala, yosasunthika pamawonekedwe a nkhope, imathandizira kupewa kutayika kwamadzi ochulukirapo pamapangidwe, kuonetsetsa kudzipatula koyenera komanso kukhulupirika bwino.
6. Fracturing Fluids: HEC imagwiritsidwa ntchito m'madzi a hydraulic fracturing kuti apereke mamasukidwe akayendedwe komanso kutayika kwamadzimadzi.Zimathandizira kunyamula ma proppants muzophulika ndikusunga kuyimitsidwa, kuwonetsetsa kuti fracture conductivity ndi kuchira kwamadzimadzi panthawi yopanga.
7. Kukondoweza Bwino: HEC ikhoza kuphatikizidwa m'madzi a acidizing ndi mankhwala ena okondoweza bwino kuti apititse patsogolo rheology yamadzimadzi, kuwongolera kutayika kwamadzimadzi, ndikuwonjezera kuyanjana kwamadzi ndi malo osungira.Izi zimathandiza kukhathamiritsa chithandizo chamankhwala ndikukulitsa zokolola zabwino.
8. Madzi Omaliza: HEC ikhoza kuwonjezeredwa kumadzi omaliza kuti asinthe kukhuthala kwawo komanso kuyimitsidwa, kuonetsetsa kuti miyala yamtengo wapatali imanyamula, kuwongolera mchenga, komanso kuyeretsa bwino pomaliza ntchito.

Hydroxyethyl cellulose (HEC) imagwira ntchito yofunika kwambiri m'malo osiyanasiyana opangira mafuta, imathandizira pakubowola bwino, kukhazikika kwa chitsime, kasamalidwe ka posungira, komanso kukhathamiritsa kwa kupanga.Kusinthasintha kwake, kuchita bwino, komanso kugwirizana ndi zowonjezera zina kumapangitsa kuti ikhale yofunika kwambiri pamakina amadzimadzi amafuta amafuta ndi mankhwala.
