Mu madzi obowola, PAC imatanthauza polyanionic cellulose, yomwe ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito popanga matope obowola. Matope obowola, omwe amadziwikanso kuti madzi obowola, amachita gawo lofunika kwambiri pakubowola zitsime zamafuta ndi gasi. Amathandiza pa ntchito zosiyanasiyana, monga kuziziritsa ndi kudzola zinthu zobowola, kunyamula zidutswazo pamwamba, kupereka kukhazikika kwa chitsime, komanso kuwongolera kuthamanga kwa mapangidwe.
Polyanionic cellulose ndi polima wosungunuka m'madzi wochokera ku cellulose, polima wachilengedwe womwe umapezeka m'zomera. PAC imawonjezeredwa kumadzi obowola kuti iwonjezere mphamvu zawo zowongolera rheology ndi kusefa.
1. Kapangidwe ka mankhwala ndi makhalidwe a polyanionic cellulose (PAC):
PAC ndi polima ya cellulose yosinthidwa yokhala ndi mphamvu ya anionic.
Kapangidwe kake ka mankhwala kamapangitsa kuti kasungunuke mosavuta m'madzi, zomwe zimapangitsa kuti pakhale njira yokhazikika.
Kapangidwe ka anionic ka PAC kamathandizira kuti igwirizane ndi zigawo zina mumadzi obowola.
2. Mphamvu zabwino za rheological:
PAC imagwiritsidwa ntchito kusintha mawonekedwe a rheological a madzi obowola.
Zimakhudza kukhuthala kwa khungu, mphamvu ya gel komanso kulamulira kutayika kwa madzi.
Kulamulira matenda a rheology ndikofunikira kwambiri pakukonza bwino kunyamula kwa zidutswa ndikusunga kukhazikika kwa wellbore.
3. Kuwongolera zosefera:
Chimodzi mwa ntchito zazikulu za PAC ndikuwongolera kutayika kwa madzi panthawi yobowola.
Imapanga keke yopyapyala, yosalowa madzi m'makoma a chitsime, zomwe zimaletsa kutayika kwa madzi obowola m'makoma.
Izi zimathandiza kusunga makhalidwe ofunikira a matope obowola ndikuletsa kuwonongeka kwa mapangidwe.
4. Kukhazikika kwa chitsime cha madzi:
PAC imathandizira kukhazikika kwa wellbore mwa kuletsa madzi ochulukirapo kuti asalowe mu kapangidwe kake.
Zimathandiza kuchepetsa kusokonezeka kwa makoma ndi mavuto ena okhudzana ndi kusakhazikika kwa wellbore.
Kukhazikika kwa chitsime cha madzi ndikofunikira kwambiri kuti ntchito zobowola ziyende bwino.
5. Mitundu ya PAC ndi ntchito zake:
Mitundu yosiyanasiyana ya PAC imapezeka kutengera kulemera kwa mamolekyulu ndi kuchuluka kwa cholowa m'malo.
Ma PAC okhala ndi kukhuthala kwakukulu nthawi zambiri amagwiritsidwa ntchito pamene pakufunika kuwongolera kwambiri rheology.
Pa ntchito zomwe cholinga chachikulu ndi kuchepetsa kutayika kwa madzi, PAC yotsika kwambiri ingakhale yabwino.
6. Zinthu zofunika kuziganizira pa chilengedwe:
PAC nthawi zambiri imaonedwa kuti ndi yotetezeka ku chilengedwe chifukwa imatha kuwonongeka.
Kuwunika momwe zinthu zingakhudzire chilengedwe kunachitika kuti zitsimikizire kuti kugwiritsa ntchito bwino ndi kutaya madzi obowola omwe ali ndi PAC kukuchitika.
7. Kuwongolera khalidwe ndi kuyesa:
Njira zowongolera khalidwe zimayikidwa kuti zitsimikizire kuti PAC ikugwira ntchito bwino mumadzi obowola.
Mayeso osiyanasiyana, kuphatikizapo kuyeza kwa rheological ndi mayeso otaya madzi, adachitidwa kuti awone momwe matope obowola okhala ndi PAC amagwirira ntchito.
8. Mavuto ndi zatsopano:
Ngakhale kuti imagwiritsidwa ntchito kwambiri, mavuto monga kukhazikika kwa kutentha komanso kugwirizana ndi zowonjezera zina zingabuke.
Kafukufuku wopitilira ndi zatsopano zimaperekedwa kuti athetse mavutowa ndikukweza magwiridwe antchito onse a PAC mumadzi obowola.
Polyanionic cellulose (PAC) ndi gawo lofunikira kwambiri pakupanga madzi obowola ndipo limathandizira kulamulira rheology, kuwongolera kusefa ndi kukhazikika kwa wellbore. Kapangidwe kake kapadera kamaipangitsa kukhala yowonjezera yofunika kwambiri mumakampani obowola mafuta ndi gasi, zomwe zimagwira ntchito yofunika kwambiri pakupambana ndi kuchita bwino kwa ntchito zobowola.
