Polyanionic Cellulose High Viscosity (PAC HV)

High viscosity polyanionic cellulose (PAC-HV) ndi mtundu wa cellulose yochokera ku cellulose yomwe imagwiritsidwa ntchito kwambiri ngati viscosifier ndi zowonjezera zowongolera kutayika kwamadzi m'mafakitale osiyanasiyana, makamaka pobowola ndi kumaliza madzi ofufuza mafuta ndi gasi. Nazi mwachidule za PAC-HV:

1. Mapangidwe: PAC-HV imachokera ku cellulose yachilengedwe kupyolera mu kusintha kwa mankhwala kuti adziwe magulu a carboxymethyl ndikuwonjezera kusungunuka kwake m'madzi. Kuchuluka kwa kulowetsa m'malo ndi kulemera kwa maselo kumatsimikizira kukhuthala ndi mawonekedwe a PAC-HV.

2. Kachitidwe:

• Viscosifier: PAC-HV imapereka mamasukidwe apamwamba pamayankho amadzi, kupangitsa kuti ikhale yogwira mtima pakukulitsa zamadzimadzi zobowola ndikukweza mphamvu yake yonyamula podula zoboola.
• Fluid Loss Control: PAC-HV imapanga keke yopyapyala yopyapyala pakhoma la borehole, imachepetsa kutayika kwamadzi mukupanga ndikusunga chitsime cha bata.
• Rheology Modifier: PAC-HV imakhudza machitidwe oyenda komanso mawonekedwe amadzimadzi akubowola, kukulitsa kuyimitsidwa kwa zolimba ndikuchepetsa kukhazikika.

3. Mapulogalamu:

• Kubowola Mafuta ndi Gasi: PAC-HV imagwiritsidwa ntchito kwambiri pobowola zotengera madzi pobowola kumtunda ndi kunyanja. Zimathandizira kukhazikika kwa Wellbore, kupewa kuwonongeka kwa mapangidwe, komanso kumathandizira pakubowola koyenera.
• Ntchito yomanga: PAC-HV imagwiritsidwa ntchito ngati chokhuthala komanso chosungira madzi m'mapangidwe a simenti monga ma grouts, slurries, ndi matope omwe amagwiritsidwa ntchito pomanga.
• Mankhwala: M'mapangidwe amankhwala, PAC-HV imagwira ntchito ngati chomangira, chosokoneza, komanso chowongolera chotulutsa mumapiritsi ndi makapisozi.

4. Katundu:

• Kuwoneka Kwakukulu: PAC-HV imawonetsa kukhuthala kwakukulu mu yankho, kumapereka katundu wokhuthala kwambiri ngakhale pamlingo wochepa.
• Kusungunuka kwamadzi: PAC-HV imasungunuka mosavuta m'madzi, kulola kulowetsedwa mosavuta m'makina amadzimadzi popanda kufunikira kwa zosungunulira zowonjezera kapena dispersants.
• Kukhazikika kwa Matenthedwe: PAC-HV imasunga kukhuthala kwake ndi mawonekedwe ake pamatenthedwe osiyanasiyana omwe amakumana nawo pakubowola ndi ntchito zina zamafakitale.
• Kulekerera Mchere: PAC-HV imawonetsa kuyanjana kwabwino ndi kuchuluka kwa mchere ndi ma brines omwe amakumana nawo m'malo opangira mafuta.

5. Ubwino ndi Mafotokozedwe:

• Zogulitsa za PAC-HV zimapezeka m'magiredi osiyanasiyana komanso mawonekedwe ogwirizana ndi magwiritsidwe antchito komanso zofunikira pakuchita.
• Njira zowongolera zabwino zimatsimikizira kusasinthika komanso kutsata miyezo yamakampani, kuphatikiza mafotokozedwe a API (American Petroleum Institute) pakubowola zowonjezera zamadzimadzi.

Mwachidule, PAC-HV ndi chowonjezera chosunthika komanso chothandiza chokhala ndi kukhuthala kwakukulu, kuwongolera kutaya kwamadzimadzi, komanso mawonekedwe a rheological, kupangitsa kuti ikhale yofunikira pazogwiritsa ntchito zosiyanasiyana zamafakitale, makamaka pakubowola mafuta ndi gasi. Kudalirika kwake, magwiridwe antchito, komanso kugwirizana ndi zowonjezera zina zimathandizira kuti zigwiritsidwe ntchito pobowola zovuta.
