PAC-LV, PAC-Hv, PAC R, Zida Zobowola Mafuta

Polyanionic cellulose (PAC) nthawi zambiri imagawika m'makalasi osiyanasiyana kutengera kulemera kwake kwa maselo, kuchuluka kwa m'malo, ndi zina. Nayi kusanthula kwamitundu yodziwika bwino ya PAC yomwe imagwiritsidwa ntchito pobowola mafuta:

1. PAC-LV (Low Viscosity):
   • PAC-LV ndi kagawo kakang'ono ka kukhuthala kwa cellulose ya polyanionic yomwe imagwiritsidwa ntchito pobowola madzi.
   • Imadziwika ndi mawonekedwe ake otsika poyerekeza ndi magiredi ena a PAC.
   • PAC-LV amagwiritsidwa ntchito pamene kuwongolera kukhuthala kocheperako komanso kutayika kwamadzimadzi kumafunika pakubowola.
2. PAC-HV (Kuwoneka Kwambiri):
   • PAC-HV ndi kawonedwe kapamwamba ka cellulose ya polyanionic yomwe imagwiritsidwa ntchito kuti ikwaniritse mamasukidwe apamwamba amadzi akubowola m'madzi.
   • Imapereka zinthu zabwino kwambiri za rheological komanso kuwongolera kutaya kwamadzimadzi, ndikupangitsa kuti ikhale yoyenera pakubowola komwe kumafunikira kuyimitsidwa kolimba.
3. PAC R (Yokhazikika):
   • PAC R, kapena kalasi yanthawi zonse PAC, ndi kalasi yapakatikati yama cellulose a polyanionic.
   • Amapereka ma viscosifying moyenera komanso kuwongolera kutaya kwamadzimadzi, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito pobowola mosiyanasiyana komwe kumafunikira kukhuthala kocheperako komanso kutayika kwamadzimadzi.

Magiredi osiyanasiyana a PAC awa amagwiritsidwa ntchito mumadzi obowola mafuta kuti akwaniritse kukhuthala kwake, rheology, ndi zolinga zowongolera kutaya kwamadzimadzi potengera momwe kubowola, mawonekedwe ake, komanso zofunikira zakukhazikika kwachitsime.

Pobowola mafuta, PAC imagwiritsidwa ntchito ngati chowonjezera chofunikira pamadzi obowola pamadzi kuti:

• Control mamasukidwe akayendedwe ndi rheology kukhathamiritsa ntchito pobowola ndi kuteteza wellbore kusakhazikika.
• Chepetsani kutayika kwamadzi mumpangidwe, kuchepetsa kuwonongeka kwa mapangidwe ndikusintha bwino zokolola.
• Imitsani mokhomerera cuttings ndi zolimba, kutsogoza awo kuchotsa ku chitsime.
• Perekani mafuta ndi kuchepetsa kukangana pakati pa chingwe chobowola ndi khoma la chitsime.

Ponseponse, PAC imagwira ntchito yofunika kwambiri ngati viscosifier komanso chowongolera kutayika kwamadzimadzi mumadzi obowola pamadzi, zomwe zimathandizira pakubowola koyenera komanso kopambana pamakampani amafuta ndi gasi.
