PAC-LV, PAC-Hv, PAC R, Mea ʻeli ʻaila

Hoʻokaʻawale pinepine ʻia ka Polyanionic cellulose (PAC) i nā papa like ʻole e pili ana i kona kaumaha molekala, ke kekelē o ka hoʻololi ʻana, a me nā waiwai ʻē aʻe. Eia kahi wehewehe ʻana o kekahi mau ʻano PAC maʻamau i hoʻohana ʻia i ka ʻoihana ʻeli ʻaila:

1. PAC-LV (ʻAʻa haʻahaʻa):
   • He haʻahaʻa ka PAC-LV ma ka mānoanoa o ka cellulose polyanionic i hoʻohana ʻia i loko o nā wai ʻeli wai.
   • Hōʻike ʻia ia e kona viscosity haʻahaʻa i hoʻohālikelike ʻia me nā papa PAC ʻē aʻe.
   • Hoʻohana pinepine ʻia ka PAC-LV i ka wā e pono ai ke kaohi ʻana i ka mānoanoa kaulike a me ka kaohi ʻana i ka pohō wai i nā hana ʻeli.
2. PAC-HV (ʻAno Mānoanoa Kiʻekiʻe):
   • ʻO ka PAC-HV kahi pae viscosity kiʻekiʻe o ka cellulose polyanionic i hoʻohana ʻia no ka hoʻokō ʻana i ka viscosity kiʻekiʻe aʻe i nā wai wili wai.
   • Hāʻawi ia i nā waiwai rheological maikaʻi loa a me ka kaohi ʻana i ka pohō wai, e kūpono ana no nā kūlana ʻeli paʻakikī kahi e pono ai ka hoʻonui ʻana i ka hoʻokuʻu ʻia ʻana o nā mea paʻa.
3. PAC R (Maʻamau):
   • ʻO PAC R, a i ʻole PAC papa maʻamau, kahi papa viscosity waena o ka polyanionic cellulose.
   • Hāʻawi ia i nā waiwai viscosifying kaulike a me ka kaohi ʻana i ka pohō wai, e kūpono ana no nā ʻano hana wili like ʻole kahi e pono ai ka viscosity kaulike a me ka kaohi ʻana i ka pohō wai.

Hoʻohana ʻia kēia mau papa like ʻole o ka PAC i nā wai ʻeli aila e hoʻokō i nā pahuhopu kikoʻī o ka viscosity, rheology, a me ka kaohi ʻana i ka pohō wai e pili ana i nā kūlana ʻeli, nā ʻano hoʻokumu, a me nā koi paʻa o ka wellbore.

I nā hana ʻeli ʻaila, hoʻohana ʻia ka PAC ma ke ʻano he mea hoʻohui koʻikoʻi i nā wai ʻeli wai e:

• E kāohi i ka viscosity a me ka rheology e hoʻomaikaʻi i ka hana ʻeli a pale i ka paʻa ʻole o ka luawai.
• E hōʻemi i ka nalowale o ke wai i loko o ke kahua, e hōʻemi ana i ka pōʻino o ke kahua a hoʻomaikaʻi i ka huahua o ka luawai.
• E hoʻokuʻu i nā ʻokiʻoki i wili ʻia a me nā mea paʻa, e kōkua ana i kā lākou wehe ʻana mai ka luawai.
• E hoʻolako i ka lubrication a hoʻēmi i ka friction ma waena o ke kaula wili a me ka paia o ka luawai.

Ma keʻano holoʻokoʻa, he kuleana koʻikoʻi ko PAC ma ke ʻano he viscosifier a me ka mea kaohi i ka pohō wai i nā wai ʻeli wai, e kōkua ana i nā hana ʻeli kūpono a holomua i ka ʻoihana aila a me ke kinoea.
