Polyanionic Cellulose

I-Polyanionic cellulose (PAC) iphuma ku-cellulose encibilika emanzini ethola ukusetshenziswa okubanzi ezinhlelweni ezihlukene zezimboni, ikakhulukazi embonini yokumba uwoyela negesi. Nasi isifinyezo se-polyanionic cellulose:

1. Ukwakheka: I-Polyanionic cellulose itholakala 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: I-PAC isetshenziswa ngokuyinhloko njenge-viscosifier kuketshezi lokumba olusekelwe emanzini. Inikeza i-viscosity oketshezini, ithuthukisa ikhono layo lokumisa okwesikhashana kanye nokuthutha ama-cuttings abhoboziwe phezulu.
• Ukulawula Ukulahleka Kwe-Fluid: I-PAC yenza ikhekhe lokuhlunga elincanyana, elingangeneli odongeni lwe-borehole, linciphisa ukulahlekelwa uketshezi ekubunjweni kwalo futhi ligcine ukuqina komthombo.
• I-Rheology Modifier: I-PAC ithonya ukuziphatha kokugeleza nezici ze-rheological zoketshezi lokumba, ithuthukisa ukumiswa kwezinto eziqinile futhi inciphise ukuzinza.

3. Izinhlelo zokusebenza:

• Ukumba Uwoyela Negesi: I-PAC iyisengezo esibalulekile kuketshezi lokumba olusekelwe emanzini olusetshenziswa ekuhloleni nasekukhiqizeni uwoyela negesi. Isiza ukulawula i-viscosity, ukulahlekelwa uketshezi, kanye ne-rheology, iqinisekisa ukusebenza kahle kokumba kanye nokuzinza kwe-wellbore.
• Ukwakhiwa: I-PAC isetshenziswa njenge-ejenti yokuqina kanye nokugcina amanzi ekwakhiweni kukasimende njengama-grouts, ama-slurries, nama-mortars asetshenziswa ezinhlelweni zokwakha.
• Ezemithi: Ekwenziweni kwemithi, i-PAC isebenza njenge-binder, disintegrant, kanye ne-ejenti ekhishwayo elawulwayo ekwakhekeni kwethebhulethi namakhephuseli.

4. Izakhiwo:

• Ukunyibilika Kwamanzi: I-PAC incibilika kalula emanzini, okuvumela ukufakwa kalula kumasistimu anamanzi ngaphandle kwesidingo sezinyibilikisi ezengeziwe noma izihlanzi.
• Ukuzinza Okuphezulu: I-PAC ibonisa ukuzinza okuphezulu kwe-thermal namakhemikhali, igcina izici zayo zokusebenza phezu kwebanga elibanzi lamazinga okushisa nezimo ze-pH.
• Ukubekezelela Usawoti: I-PAC ikhombisa ukuhambisana okuhle namazinga aphezulu kasawoti kanye ne-brines evame ukuhlangana nayo ezindaweni zasezindaweni zikawoyela.
• Ukubola kwezinto eziphilayo: I-PAC isuselwa emithonjeni evuselelekayo esekelwe ezitshalweni futhi iyakwazi ukubola, okuyenza ivumelane nemvelo.

5. Ikhwalithi Nemininingwane:

• Imikhiqizo ye-PAC 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-polyanionic cellulose iyisengezo esisebenza ngezindlela eziningi nesisebenzayo esine-viscosifying, isilawuli sokulahlekelwa uketshezi, kanye nezakhiwo ze-rheological, okuyenza ibaluleke kakhulu ekusetshenzisweni kwezimboni ezihlukahlukene, ikakhulukazi embonini yokumba uwoyela negesi. Ukuthembeka kwayo, ukusebenza, nokuhambisana kwemvelo kunomthelela ekusetshenzisweni kwayo kabanzi ezindaweni zokumba eziyinselele.
