Pobowola madzi, PAC imatanthauza polyanionic cellulose, yomwe ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito pobowola matope. Kubowola matope, komwe kumadziwikanso kuti madzi akubowola, kumagwira ntchito yofunika kwambiri pakubowola zitsime zamafuta ndi gasi. Zimagwira ntchito zosiyanasiyana, monga kuziziritsa ndi kuthira mafuta pobowola, kunyamula zodulidwa pamwamba, kupereka kukhazikika kwa chitsime, ndikuwongolera kuthamanga kwa mapangidwe.
Polyanionic cellulose ndi polima wosungunuka m'madzi wochokera ku cellulose, polima wachilengedwe wopezeka muzomera. PAC imawonjezedwa kumadzimadzi obowola kuti apititse patsogolo ma rheology ndi kusefera kwawo.
1. Mapangidwe a Chemical ndi katundu wa polyanionic cellulose (PAC):
PAC ndi polima yosinthidwa ya cellulose yokhala ndi anionic charge.
Kapangidwe kake ka mankhwala kumapangitsa kusungunuka mosavuta m'madzi, kupanga njira yokhazikika.
Mkhalidwe wa anionic wa PAC umathandizira kuti athe kulumikizana ndi zigawo zina mumadzi obowola.
2. Kupititsa patsogolo ma rheological properties:
PAC imagwiritsidwa ntchito kusintha mawonekedwe a rheological amadzimadzi akubowola.
Zimakhudza kukhuthala, mphamvu ya gel ndi kuwongolera kutaya kwamadzi.
Kuwongolera ma rheology ndikofunikira pakuwongolera zoyendera ndikusunga chitsime cha chitsime.
3. Kuwongolera kusefa:
Imodzi mwa ntchito zazikulu za PAC ndikuwongolera kutaya kwamadzimadzi panthawi yoboola.
Zimapanga keke yopyapyala, yosasunthika pamakoma a chitsime, kuteteza kutaya kwamadzimadzi obowola mu mapangidwe.
Izi zimathandiza kukhalabe zofunika za matope kubowola ndi kuteteza mapangidwe kuwonongeka.
4. Kukhazikika kwa Wellbore:
PAC imathandizira kuti chitsime chikhale chokhazikika poletsa madzi ochulukirapo kuti asalowe mu mapangidwe.
Zimathandizira kuchepetsa kukhazikika kwa masiyanidwe ndi mavuto ena okhudzana ndi kusakhazikika kwa chitsime.
Kukhazikika kwa Wellbore ndikofunikira kuti ntchito zoboola zitheke.
5. Mitundu ya PAC ndi kagwiritsidwe ntchito kake:
Magulu osiyanasiyana a PAC akupezeka kutengera kulemera kwa mamolekyu ndi kuchuluka kwa m'malo.
Ma PAC owoneka bwino kwambiri amagwiritsidwa ntchito pomwe kuwongolera kwakukulu kumafunika.
Kwa mapulogalamu omwe kuwongolera kutayika kwamadzi kumakhala kodetsa nkhawa kwambiri, PAC yotsika kwambiri ya viscosity ingakhale yabwino.
6. Zoganizira zachilengedwe:
PAC nthawi zambiri imawonedwa ngati yogwirizana ndi chilengedwe chifukwa imatha kuwonongeka.
Kuwunika kwa chilengedwe kunachitika pofuna kuonetsetsa kuti madzi obowola omwe ali ndi PAC akugwiritsidwa ntchito moyenera.
7. Kuwongolera ndi kuyesa kwabwino:
Njira zowongolera bwino zimakhazikitsidwa kuti PAC igwire bwino ntchito pobowola madzi.
Mayeso osiyanasiyana, kuphatikiza kuyeza kwa rheological ndi kuyezetsa kutaya madzimadzi, adachitidwa kuti awunikire momwe matope obowola okhala ndi PAC.
8. Zovuta ndi zatsopano:
Ngakhale kuti amagwiritsidwa ntchito ponseponse, zovuta monga kukhazikika kwa kutentha ndi kugwirizanitsa ndi zina zowonjezera zikhoza kubwera.
Kufufuza kosalekeza ndi zatsopano zaperekedwa kuti athetse zovutazi ndikuwongolera magwiridwe antchito onse a PAC pobowola madzi.
Polyanionic cellulose (PAC) ndi gawo lofunikira pakubowola kwamadzimadzi ndipo limathandizira kuwongolera kwa rheology, kusefera komanso kukhazikika kwamadzi. Kapangidwe kake kapadera kamapangitsa kuti ikhale chowonjezera chofunikira pakubowola mafuta ndi gasi, zomwe zimagwira ntchito yofunika kwambiri pakubowola bwino komanso kuchita bwino.
