PAC-LV, PAC-Hv, PAC R, Oiri Drilling Material

Polyanionic cellulose (PAC) inowanzoiswa mumagiredhi akasiyana zvichienderana nehuremu hwayo hwemamorekuru, dhigirii rekutsiva, uye zvimwe zvinhu.Heano kuparara kwemamwe marudzi akajairika ePAC anoshandiswa muindasitiri yekuchera oiri:

1. PAC-LV (Low Viscosity):
   • PAC-LV igiredhi yakaderera viscosity ye polyanionic cellulose inoshandiswa mumvura-inocherwa zvinwiwa.
   • Iyo inoratidzirwa neiyo yakaderera viscosity kana ichienzaniswa nemamwe mamakisi ePAC.
   • PAC-LV inowanzo shandiswa kana iri pakati nepakati viscosity control uye kudzora kurasikirwa kwemvura kunodiwa mukuchera.
2. PAC-HV (High Viscosity):
   • PAC-HV yakakwira viscosity giredhi ye polyanionic cellulose inoshandiswa kuwana yakakwira viscosity mumvura-inocherwa zvinwiwa.
   • Inopa yakanakisa rheological zvivakwa uye kutadza kurasikirwa kwemvura, zvichiita kuti ive yakakodzera kune inonetsa mamiriro ekuchera uko kuwedzera kumiswa kwezvakaoma kunodiwa.
3. PAC R (Regular):
   • PAC R, kana yenguva dzose-giredhi PAC, iri yepakati-renji viscosity giredhi re polyanionic cellulose.
   • Inopa yakaenzana viscosifying uye fluid kurasikirwa kwekudzora zvivakwa, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekuchera zvikumbiro uko zvine mwero viscosity uye kutadza kurasikirwa kwemvura kunodiwa.

Aya magiredhi akasiyana ePAC anoshandiswa mumafuta ekuchera zvinwiwa kuti awane chaiyo viscosity, rheology, uye kurasikirwa kwemvura kurasikirwa zvibodzwa zvichienderana nemamiriro ekuchera, maitiro ekuumbwa, uye kugadzikana kwetsime zvinodiwa.

Mumabasa ekuchera oiri, PAC inoshandiswa sechinhu chakakosha mukuwedzera mumvura-yakavakirwa mvura yekuchera ku:

• Kudzora viscosity uye rheology kukwidziridza mashandiro ekuchera uye kudzivirira kusagadzikana kwematsime.
• Deredzai kurasikirwa kwemvura mukuumbwa, kuderedza kukuvadzwa kwekuumbwa uye kunatsiridza kugadzirwa zvakanaka.
• Kumisa zvakachekwa zvakachekwa uye zvakasimba, zvichibatsira kubviswa kwavo kubva mutsime.
• Ipa mafuta uye kuderedza kukweshera pakati pechibooreso nemadziro etsime.

Pakazere, PAC inobata basa rakakosha seviscosifier uye yekurasikirwa kwemvura yekudzora mumiriri mumvura-yakavakirwa mvura yekuchera, ichibatsira mukuita kwakanaka uye kwakabudirira kuchera muindasitiri yeoiri negasi.
