PAC-LV, PAC-Hv, PAC R, Zinthu Zobowolera Mafuta

Polyanionic cellulose (PAC) nthawi zambiri imagawidwa m'magulu osiyanasiyana kutengera kulemera kwake kwa mamolekyulu, kuchuluka kwa cholowa m'malo, ndi zina. Nayi kusanthula kwa mitundu yodziwika bwino ya PAC yomwe imagwiritsidwa ntchito mumakampani obowola mafuta:

1. PAC-LV (Kukhuthala Kochepa):
   • PAC-LV ndi polyanionic cellulose yomwe imakhala ndi viscosity yochepa yomwe imagwiritsidwa ntchito mumadzi obowola pogwiritsa ntchito madzi.
   • Imadziwika ndi kukhuthala kwake kochepa poyerekeza ndi mitundu ina ya PAC.
   • PAC-LV nthawi zambiri imagwiritsidwa ntchito pamene pakufunika kuwongolera pang'ono kukhuthala kwa madzi ndi kutayika kwa madzi m'mabowo.
2. PAC-HV (Kukhuthala Kwambiri):
   • PAC-HV ndi polyanionic cellulose yokhala ndi viscosity yapamwamba kwambiri yomwe imagwiritsidwa ntchito kuti ikwaniritse viscosity yayikulu mumadzi obowola pogwiritsa ntchito madzi.
   • Imapereka mphamvu zabwino kwambiri za rheological komanso kuwongolera kutayika kwa madzi, zomwe zimapangitsa kuti ikhale yoyenera pamavuto obowola komwe kumafunika kuyimitsidwa kwakukulu kwa zinthu zolimba.
3. PAC R (Wamba):
   • PAC R, kapena PAC ya kalasi yokhazikika, ndi kalasi yapakati ya polyanionic cellulose yomwe imakhala ndi viscosity grade.
   • Imapereka mphamvu zolimbitsa bwino komanso zowongolera kutayika kwa madzi, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito mitundu yosiyanasiyana ya kubowola komwe kumafunika kukhuthala pang'ono komanso kutayika kwa madzi.

Ma PAC osiyanasiyana awa amagwiritsidwa ntchito mumadzi obowola mafuta kuti akwaniritse zolinga zinazake zowongolera kukhuthala, rheology, ndi kutayika kwa madzi kutengera momwe kubowola kulili, mawonekedwe ake, ndi zofunikira pakukhazikika kwa wellbor.

Pa ntchito zobowola mafuta, PAC imagwiritsidwa ntchito ngati chowonjezera chofunikira mu madzi obowola pogwiritsa ntchito madzi kuti:

• Sinthani kukhuthala ndi rheology kuti muwongolere magwiridwe antchito a kubowola ndikuletsa kusakhazikika kwa mabowo a wellbore.
• Chepetsani kutayika kwa madzi m'mapangidwe a zinthu, kuchepetsa kuwonongeka kwa mapangidwe a zinthu ndikuwonjezera kukolola bwino kwa zinthu m'chitsime.
• Ikani zidutswa zobowoledwa ndi zolimba, zomwe zimathandiza kuti zichotsedwe m'chitsime.
• Perekani mafuta odzola ndi kuchepetsa kukangana pakati pa chingwe chobowolera ndi khoma lobowola chitsime.

Ponseponse, PAC ili ndi gawo lofunika kwambiri monga chothandizira kuwononga ma viscosifier ndi madzi m'madzi obowola, zomwe zimathandiza kuti ntchito zobowola ziyende bwino komanso bwino mumakampani amafuta ndi gasi.
