Polyanionic cellulose viscosity ephantsi (PAC-LV)

I-Polyanionic cellulose low viscosity (PAC-LV) luhlobo lwe-polyanionic cellulose edla ngokusetyenziswa njenge-additives kwi-drilling fluids yokuhlola i-oyile negesi. Nantsi isishwankathelo sePAC-LV kunye nendima yayo kwimisebenzi yokomba:

1. Ukubunjwa: I-PAC-LV ithathwe kwi-cellulose, i-polymer yendalo efumaneka kwizityalo, ngokuguqulwa kweekhemikhali. Amaqela e-Carboxymethyl aziswa kwi-cellulose backbone, eyinika iimpawu ze-anionic (ezihlawuliswa kakubi).
2. Ukusebenza:
   • I-Viscosifier: Ngelixa i-PAC-LV ine-viscosity esezantsi xa ithelekiswa namanye amabanga e-polyanionic cellulose, isasebenza njenge-viscosifier kulwelo lokomba. Inceda ukwandisa i-viscosity ye-fluid, inceda ekumisweni nasekuthuthweni kwe-cuttings drilled.
   • Ulawulo lwelahleko yolwelo: I-PAC-LV ikwanegalelo kulawulo lwelahleko yolwelo ngokwenza ikeyiki ebhityileyo yokuhluza kudonga lomngxuma, inciphisa ilahleko yolwelo lokugrumba ekubunjweni kwayo.
   • I-Rheology Modifier: I-PAC-LV inefuthe kwindlela yokuziphatha kunye neempawu zerheological zolwelo lokomba, iphucula ukunqunyanyiswa kwezinto eziqinileyo kunye nokunciphisa ukuzinza.
3. Usetyenziso:
   • I-Oli kunye neGesi yoKwemba: I-PAC-LV isetyenziselwa ukugrumba ulwelo olusekwe emanzini ukuphonononga i-oyile negesi kunye nokuveliswa. Inceda ukuphucula uzinzo lwe-wellbore, ukuthintela umonakalo wokwakheka, kunye nokuphucula ukusebenza kakuhle kokomba.
   • Ulwakhiwo: I-PAC-LV inokuphinda isetyenziswe njengesixhobo sokujiyisa kunye nokugcina amanzi kwimixube yesamente efana neegrouts, i-slurries, kunye nodaka olusetyenziswa kwizicelo zokwakha.
   • I-Pharmaceuticals: Kuqulunqo lwamachiza, i-PAC-LV inokusebenza njenge-binder, i-disintegrant, kunye ne-ejenti elawulwayo yokukhululwa kwi-tablet kunye ne-capsule formulations.
4. Iinkcazelo ngeempawu:
   • Ukunyibilika kwamanzi: I-PAC-LV inyibilika ngokulula emanzini, ivumela ukuba kube lula ukufakwa kwiinkqubo zolwelo lokomba olumanzi.
   • Ukuzinza kweThermal: I-PAC-LV igcina iimpawu zayo zokusebenza kuluhlu olubanzi lwamaqondo obushushu adibana nawo kwimisebenzi yokomba.
   • Ukunyamezelwa kweTyuwa: I-PAC-LV ibonisa ukuhambelana okuhle kunye namazinga aphezulu eetyuwa kunye neebrines eziqhelekileyo ezidibana nazo kwiindawo zeoli.
   • I-Biodegradability: Njengezinye iifom ze-polyanionic cellulose, i-PAC-LV ithathwe kwimithombo yokuhlaziywa kwezityalo ezisekelwe kwizityalo kwaye i-biodegradable, iyenza ukuba ivumelane nokusingqongileyo.
5. Umgangatho kunye neeNgcaciso:
   • Iimveliso ze-PAC-LV zifumaneka kumabakala ahlukeneyo kunye neenkcukacha ezilungiselelwe iimfuno zolwelo oluthile lokomba.
   • Amanyathelo olawulo lomgangatho aqinisekisa ukuhambelana kunye nokuthotyelwa kwemigangatho yoshishino, kubandakanywa ne-API (i-American Petroleum Institute) inkcazo ye-drilling fluid additives.

Isishwankathelo, i-polyanionic cellulose i-viscosity ephantsi (i-PAC-LV) yongezwa okubalulekileyo kumanzi okugaya asekelwe emanzini, ukubonelela nge-viscosification, ukulawulwa kwelahleko yamanzi, kunye neempawu zokuguqulwa kwe-rheology ukunyusa ukusebenza kokugaya kunye nokuzinza kwe-wellbore kwi-oyile kunye nokuhlola igesi.
