I-Polyanionic Cellulose High Viscosity (PAC HV)

I-high viscosity polyanionic cellulose (i-PAC-HV) iwuhlobo lokuphuma kwe-cellulose olusetshenziswa kakhulu njengesithako se-viscosifier kanye nesengezo sokulawula ukulahlekelwa uketshezi ezimbonini ezihlukahlukene, ikakhulukazi ekubholani nasekuqedeni uketshezi lokuhlola uwoyela negesi. Nakhu ukubuka konke kwe-PAC-HV:

1. Ukwakheka: I-PAC-HV isuselwa ku-cellulose yemvelo ngokuguqulwa kwamakhemikhali ukuze yethule amaqembu e-carboxymethyl futhi ithuthukise ukunyibilika kwayo emanzini. Izinga lokushintsha kanye nesisindo sengqamuzana linquma i-viscosity nezici zokusebenza ze-PAC-HV.

2. Ukusebenza:

• I-Viscosifier: I-PAC-HV inika i-viscosity ephezulu ezixazululweni ezinamanzi, iyenze isebenze kahle ekuqiniseni uketshezi lokumba kanye nokuthuthukisa umthamo wazo wokusikwa kokumba.
• Ukulawula Ukulahleka Kwe-Fluid: I-PAC-HV yenza ikhekhe lokuhlunga elincanyana, elingangeneki odongeni lwe-borehole, linciphisa ukulahlekelwa uketshezi ekubunjweni kwalo futhi ligcine ukuqina komthombo.
• I-Rheology Modifier: I-PAC-HV inomthelela ekuziphatheni kokugeleza nezici ze-rheological zoketshezi lokumba, ithuthukisa ukumiswa kokuqinile kanye nokunciphisa ukuhlaliswa.

3. Izinhlelo zokusebenza:

• Ukumba Uwoyela Negesi: I-PAC-HV isetshenziswa kakhulu kuketshezi lokumba olusekelwe emanzini kukho kokubili imisebenzi yokumba ogwini nasogwini. Isiza ukugcina ukuzinza kwe-wellbore, ivimbele ukulimala kokubunjwa, futhi yenze kube lula ukusebenza kahle kokumba.
• Ukwakhiwa: I-PAC-HV isetshenziswa njenge-ejenti yokuqina kanye nokugcina amanzi ekwenziweni kukasimende njengama-grouts, ama-slurries, nama-mortar asetshenziswa ezinhlelweni zokwakha.
• Ezemithi: Ekwenziweni kwemithi, i-PAC-HV isebenza njenge-binder, disintegrant, kanye ne-ejenti ekhishwayo elawulwayo ekwakhekeni kwethebhulethi namacapsules.

4. Izakhiwo:

• I-Viscosity Ephezulu: I-PAC-HV ikhombisa i-viscosity ephezulu esixazululweni, ihlinzeka ngezakhiwo ezinhle kakhulu zokujiya ngisho nasezindaweni eziphansi zokugxila.
• Ukunyibilika Kwamanzi: I-PAC-HV incibilika kalula emanzini, okuvumela ukufakwa kalula ezinhlelweni ezinamanzi ngaphandle kwesidingo sezinyibilikisi ezengeziwe noma izihlanzi.
• Ukuzinza Kwe-Thermal: I-PAC-HV igcina i-viscosity yayo nezici zokusebenza phezu kwebanga elibanzi lamazinga okushisa ahlangatshezwana nawo ekubholeni nezinye izinhlelo zokusebenza zezimboni.
• Ukubekezelela Usawoti: I-PAC-HV ikhombisa ukuhambisana okuhle namazinga aphezulu kasawoti kanye ne-brines evame ukuhlangana nayo ezindaweni zamafutha.

5. Ikhwalithi Nemininingwane:

• Imikhiqizo ye-PAC-HV itholakala ngamabanga ahlukahlukene kanye nokucaciswa okuklanyelwe izinhlelo zokusebenza ezithile kanye nezidingo zokusebenza.
• Izinyathelo zokulawula ikhwalithi ziqinisekisa ukuvumelana nokuhambisana nezindinganiso zomkhakha, okuhlanganisa imininingwane ye-API (American Petroleum Institute) yokumba izithasiselo zoketshezi.

Kafushane, i-PAC-HV iyisengezo esisebenza ngezindlela eziningi nesisebenzayo esine-viscosity ephezulu, isilawuli sokulahlekelwa uketshezi, kanye nezakhiwo ze-rheological, okuyenza ibaluleke kakhulu ekusetshenzisweni kwezimboni ezihlukahlukene, ikakhulukazi emisebenzini yokumba uwoyela negesi. Ukuthembeka kwayo, ukusebenza, nokuhambisana nezinye izithasiselo kunomthelela ekusetshenzisweni kwayo kabanzi ezindaweni zokumba eziyinselele.
