I-Polyanionic cellulose viscosity ephansi (PAC-LV)

I-Polyanionic cellulose low viscosity (PAC-LV) iwuhlobo lwe-polyanionic cellulose oluvame ukusetshenziswa njengesithako ekumbeni uketshezi lokuhlola uwoyela negesi. Nakhu ukubuka konke kwe-PAC-LV kanye neqhaza layo emisebenzini yokumba:

1. Ukwakheka: I-PAC-LV isuselwa ku-cellulose, i-polymer yemvelo etholakala ezitshalweni, ngokuguqulwa kwamakhemikhali. Amaqembu e-carboxymethyl ethulwa kumgogodla we-cellulose, awunikeze izakhiwo ze-anionic (ezikhokhiswa kabi).
2. Ukusebenza:
   • I-Viscosifier: Nakuba i-PAC-LV ine-viscosity ephansi uma iqhathaniswa namanye amabanga e-polyanionic cellulose, isasebenza njenge-viscosifier kuketshezi lokumba. Kuyasiza ukukhulisa i-viscosity yoketshezi, kusiza ekumisweni nasekuthuthweni kwama-cuttings aqoshiwe.
   • Ukulawula Ukulahleka Koketshezi: I-PAC-LV iphinde ibe negalelo ekulawuleni ukulahlekelwa uketshezi ngokwenza ikhekhe lesihlungi elincanyana odongeni lwe-borehole, linciphise ukulahlekelwa uketshezi lokumba ekubunjweni kwalo.
   • I-Rheology Modifier: I-PAC-LV ithonya ukuziphatha kokugeleza nezici ze-rheological zoketshezi lokumba, ithuthukisa ukumiswa kwezinto eziqinile kanye nokunciphisa ukuzinza.
3. Izicelo:
   • Ukumba Uwoyela Negesi: I-PAC-LV isetshenziswa oketshezini lokumba olususelwe emanzini ukuhlola nokukhiqiza uwoyela negesi. Isiza ukuthuthukisa ukuzinza kwe-wellbore, ivimbele ukulimala kokwakheka, futhi ithuthukise ukusebenza kahle kokumba.
   • Ukwakhiwa: I-PAC-LV ingase futhi isetshenziswe njenge-ejenti yokuqina kanye nokugcina amanzi ekwenziweni kukasimende njengama-grouts, ama-slurries, nama-mortar asetshenziswa ezinhlelweni zokwakha.
   • Ezemithi: Ekwenziweni kwemithi, i-PAC-LV ingasebenza njengesibopho, idilize, futhi ikhiphe i-ejenti elawulwayo ekwakhekeni kwethebhulethi namakhephuseli.
4. Izakhiwo:
   • Ukunyibilika Kwamanzi: I-PAC-LV incibilika kalula emanzini, okuvumela ukufakwa kalula ezinhlelweni zoketshezi lokumba olunamanzi.
   • Ukuzinza Kwe-Thermal: I-PAC-LV igcina izici zayo zokusebenza phezu kwebanga elibanzi lokushisa okuhlangatshezwana nalo emisebenzini yokumba.
   • Ukubekezelela Usawoti: I-PAC-LV ikhombisa ukuhambisana okuhle namazinga aphezulu kasawoti kanye ne-brines evame ukuhlangana nayo ezindaweni zamafutha.
   • I-Biodegradability: Njengezinye izinhlobo ze-polyanionic cellulose, i-PAC-LV itholakala emithonjeni evuselelekayo esekelwe ezitshalweni futhi iyakwazi ukubola, okuyenza ivumelane nemvelo.
5. Ikhwalithi Nemininingwane:
   • Imikhiqizo ye-PAC-LV itholakala ngamabanga ahlukahlukene kanye nokucaciswa okuvunyelaniswe nezidingo ezithile zoketshezi lokumba.
   • Izinyathelo zokulawula ikhwalithi ziqinisekisa ukuvumelana nokuhambisana nezindinganiso zomkhakha, okuhlanganisa imininingwane ye-API (American Petroleum Institute) yokumba izithasiselo zoketshezi.

Kafushane, i-polyanionic cellulose low viscosity (PAC-LV) iyisengezo esibalulekile oketshezini lokumba olusekelwe emanzini, oluhlinzeka nge-viscosification, ukulawulwa kokulahlekelwa uketshezi, kanye nezakhiwo zokuguqula i-rheology ukuze kuthuthukiswe ukusebenza kokumba nokuzinza kwe-wellbore ekuhloleni uwoyela negesi.
