Hydroxyethylcellulose (HEC) imagwira ntchito yofunika kwambiri pakubowola mafuta, makamaka pobowola madzi kapena matope. Kubowola madzimadzi n'kofunika kwambiri pobowola chitsime chamafuta, kumapereka ntchito zambiri monga kuziziritsa ndi zobowola mafuta, kunyamula zodula zoboola pamwamba, ndikusunga chitsime cha bata. HEC ndi chowonjezera chachikulu mumadzi obowola awa, kuthandiza kuwongolera magwiridwe antchito awo onse.
Chiyambi cha Hydroxyethyl Cellulose (HEC):
1. Kapangidwe ka mankhwala ndi katundu:
Hydroxyethyl cellulose ndi nonionic, madzi sungunuka polima opangidwa ndi mankhwala kusinthidwa mapadi.
Gulu la hydroxyethyl mu kapangidwe kake limapangitsa kuti lisungunuke m'madzi ndi mafuta, ndikupangitsa kuti likhale losinthasintha.
Kulemera kwake kwa mamolekyulu ndi kuchuluka kwa kulowetsa m'malo kumakhudzanso mawonekedwe ake, omwe ndi ofunikira kwambiri pakuchita kwake mumadzi obowola.
2. Kusintha kwa Rheological:
HEC imagwiritsidwa ntchito ngati rheology modifier, yomwe imakhudza kayendedwe ka kayendedwe ka madzi ndi kukhuthala kwamadzi obowola.
Kulamulira rheological katundu n'kofunika kuti optimizing ntchito ya madzi pobowola pansi osiyana downhole mikhalidwe.
3. Kuwongolera kusefa:
HEC imagwira ntchito ngati wothandizira kusefera, kuteteza kutaya kwamadzi ochulukirapo mu mapangidwe.
Polima imapanga keke yopyapyala, yosasunthika pachitsime, ndikuchepetsa kulowerera kwamadzi obowola m'miyala yozungulira.
4. Kuyeretsa ndi kupachikidwa:
HEC imathandiza kuyimitsa kudula, kuwalepheretsa kukhazikika pansi pa chitsime.
Izi zimapangitsa kuti chitsime chiyeretsedwe bwino, chimapangitsa kuti chitsimecho chikhale choyera komanso kuti asatsekeke zomwe zingalepheretse kubowola.
5. Mafuta ndi kuziziritsa:
Mafuta opangira mafuta a HEC amathandizira kuchepetsa kukangana pakati pa chingwe chobowola ndi chitsime, potero amachepetsa kuwonongeka ndi kung'ambika kwa zida zobowola.
Zimathandizanso kuchotsa kutentha, kumathandizira kuziziritsa pobowola pobowola.
6. Kukhazikika kwapangidwe:
HEC imakulitsa kukhazikika kwa chitsime pochepetsa chiopsezo cha kuwonongeka kwa mapangidwe.
Zimathandiza kusunga kukhulupirika kwa chitsime popewa kugwa kapena kugwa kwa miyala yozungulira.
7. Madzi obowola pogwiritsa ntchito madzi:
HEC imagwiritsidwa ntchito kwambiri pobowola madzi opangira madzi kuti apereke mamasukidwe akayendedwe komanso kukhazikika kwamadzi obowola.
Kugwirizana kwake ndi madzi kumapangitsa kukhala koyenera kupanga madzi obowola omwe sakonda zachilengedwe.
8. Kanikizani madzi akubowola:
M'madzi oletsa kubowola, HEC imathandizira kuwongolera ma shale hydration, kupewa kukula, ndikuwongolera kukhazikika kwa chitsime.
9. Malo otentha kwambiri:
HEC ndi yokhazikika komanso yoyenera kugwiritsidwa ntchito pobowola kutentha kwambiri.
Makhalidwe ake ndi ofunikira kuti asunge mphamvu yamadzi obowola pansi pa kutentha kwakukulu.
10. Kuphatikiza kowonjezera:
HEC itha kugwiritsidwa ntchito limodzi ndi zina zobowola madzi zowonjezera monga ma polima, surfactants ndi wolemera wothandizila kukwaniritsa kufunika madzimadzi katundu.
11. Kuchepetsa kumeta ubweya:
Kumeta ubweya womwe umakumana nawo pakubowola kungayambitse HEC kunyozeka, kukhudza ma rheological properties pakapita nthawi.
Kupanga koyenera kowonjezera ndi kusankha kungachepetse zovuta zokhudzana ndi kukameta ubweya.
12. Kukhudza chilengedwe:
Ngakhale kuti HEC nthawi zambiri imatengedwa kuti ndi yogwirizana ndi chilengedwe, kukhudzidwa kwa chilengedwe kwa madzi obowola, kuphatikizapo HEC, ndi mutu wodetsa nkhaŵa ndi kufufuza kosalekeza.
13. Kuganizira zamtengo:
Kufunika kwa mtengo wogwiritsira ntchito HEC pobowola madzi ndikuganiziridwa, ndi ogwira ntchito akuyesa ubwino wa zowonjezerazo motsutsana ndi ndalama.
Pomaliza:
Mwachidule, hydroxyethyl cellulose ndiwowonjezera wofunikira pakubowola mafuta, zomwe zimathandiza kuti ntchito yobowola ikhale yopambana komanso yogwira ntchito bwino. Ntchito zake zingapo, kuphatikiza kusintha kwa rheology, kuwongolera kusefera, kuyeretsa mabowo ndi kuthira mafuta, zimapangitsa kuti ikhale gawo lofunikira pakubowola madzi. Pamene ntchito zobowola zikupitabe patsogolo ndipo makampani akukumana ndi zovuta zatsopano komanso malingaliro a chilengedwe, HEC ikupitirizabe kugwira ntchito yofunikira poonetsetsa kuti ntchito zoboola mafuta zikuyenda bwino. Kupitilira kafukufuku ndi chitukuko chaukadaulo wapolymer chemistry ndi kubowola madzimadzi ukadaulo zitha kupititsa patsogolo kupita patsogolo komanso kukonza kagwiritsidwe ntchito ka cellulose ya hydroxyethyl pamakampani amafuta ndi gasi.
