Polyanionic cellulose low viscosity (PAC-LV)

Polyanionic cellulose low viscosity (PAC-LV) ndi mtundu wa cellulose ya polyanionic yomwe imagwiritsidwa ntchito ngati chowonjezera pobowola madzi pofufuza mafuta ndi gasi. Nazi mwachidule za PAC-LV ndi ntchito yake pakubowola:

1. Kapangidwe: PAC-LV imachokera ku cellulose, polima wachilengedwe wopezeka muzomera, kudzera mukusintha kwamankhwala. Magulu a carboxymethyl amalowetsedwa pamsana wa cellulose, ndikuupatsa mphamvu ya anionic (yopanda pake).
2. Kagwiridwe ntchito:
   • Viscosifier: Ngakhale PAC-LV ili ndi kukhuthala kochepa poyerekeza ndi magulu ena a polyanionic cellulose, imagwirabe ntchito ngati viscosifier mumadzi obowola. Zimathandiza kuonjezera mamasukidwe akayendedwe a madzimadzi, kuthandiza kuyimitsidwa ndi kunyamula mokhomerera cuttings.
   • Fluid Loss Control: PAC-LV imathandiziranso kuti madzi asatayike popanga keke yopyapyala pakhoma la borehole, kuchepetsa kutayika kwamadzi obowola popanga.
   • Rheology Modifier: PAC-LV imakhudza kayendetsedwe ka kayendetsedwe kake ndi machitidwe a rheological a madzi obowola, kupititsa patsogolo kuyimitsidwa kwa zolimba ndikuchepetsa kukhazikika.
3. Mapulogalamu:
   • Kubowola Mafuta ndi Gasi: PAC-LV imagwiritsidwa ntchito pobowola madzi pofufuza ndi kupanga mafuta ndi gasi. Zimathandizira kukhazikika kwa chitsime, kupewa kuwonongeka kwa mapangidwe, komanso kupititsa patsogolo kubowola bwino.
   • Zomangamanga: PAC-LV itha kugwiritsidwanso ntchito ngati chokhuthala ndi kusunga madzi mumipangidwe ya simenti monga ma grouts, slurries, ndi matope omwe amagwiritsidwa ntchito pomanga.
   • Mankhwala: M'mapangidwe amankhwala, PAC-LV imatha kugwira ntchito ngati chomangira, chosokoneza, komanso chowongolera chotulutsa mumapiritsi ndi makapisozi.
4. Katundu:
   • Kusungunuka kwamadzi: PAC-LV imasungunuka mosavuta m'madzi, zomwe zimapangitsa kuti zikhale zosavuta kuziyika m'makina obowola amadzimadzi.
   • Kukhazikika kwa Matenthedwe: PAC-LV imasunga mawonekedwe ake pamatenthedwe osiyanasiyana omwe amakumana nawo pobowola.
   • Kulekerera Mchere: PAC-LV imawonetsa kuyanjana kwabwino ndi kuchuluka kwa mchere ndi ma brines omwe amapezeka nthawi zambiri m'malo opangira mafuta.
   • Kuwonongeka kwachilengedwe: Monga mitundu ina ya cellulose ya polyanionic, PAC-LV imachokera kuzinthu zongowonjezwdwa zozikidwa pazitsamba ndipo imatha kuwonongeka, kupangitsa kuti ikhale yogwirizana ndi chilengedwe.
5. Ubwino ndi Mafotokozedwe:
   • Zogulitsa za PAC-LV zimapezeka m'makalasi osiyanasiyana komanso mawonekedwe ogwirizana ndi zofunikira zamadzimadzi pobowola.
   • Njira zowongolera zabwino zimatsimikizira kusasinthika komanso kutsata miyezo yamakampani, kuphatikiza mafotokozedwe a API (American Petroleum Institute) pakubowola zowonjezera zamadzimadzi.

Mwachidule, polyanionic cellulose low viscosity (PAC-LV) ndi chowonjezera chofunikira mumadzi obowola opangidwa ndi madzi, kupereka viscosification, kuwongolera kutayika kwamadzimadzi, komanso kusintha kwa ma rheology kuti apititse patsogolo ntchito yoboola komanso kukhazikika kwabwino kwamafuta ndi gasi.
