I-CMC kunye nePAC idlala njani indima kwishishini leoli?

I-sodium carboxymethyl cellulose (CMC) kunye ne-polyanionic cellulose (PAC) zombini zisetyenziswa ngokubanzi kwishishini leoli, ngakumbi ekubhobhozeni nasekugqibeni ulwelo. Badlala indima ebalulekileyo ngenxa yokukwazi ukuguqula iipropati ze-rheological, ukulawula ilahleko yolwelo, kunye nokuphucula uzinzo lwe-wellbore. Nantsi indlela iCMC kunye nePAC ezisetyenziswa ngayo kwishishini leoli:

1. Ukugrumba izongezo zolwelo:
   • CMC kunye PAC zisetyenziswa ngokuqhelekileyo njengezongezo emanzini-based sokomba ulwelo ukulawula iimpawu rheological ezifana viscosity, inqaku isivuno, kunye nokulahlekelwa ulwelo.
   • Zisebenza njenge-viscosifiers, zinyusa i-viscosity ye-drilling fluid ukuthutha i-drill cuttings ukuya phezulu kunye nokugcina uzinzo lwe-wellbore.
   • Ukongeza, bancedisa ukulawula ilahleko yolwelo ngokwenza ikeyiki ecekethekileyo, enganyangekiyo yokucoca kudonga lomthombo, ukunciphisa ilahleko yolwelo kwiindlela ezinokungena kunye nokugcina uxinzelelo lwe-hydrostatic.
2. Ulawulo lwelahleko yolwelo:
   • I-CMC kunye ne-PAC zi-arhente ezisebenzayo zokulawula ilahleko kwiincindi zokomba. Benza ikeyiki ecekethekileyo, eyomelelayo yokucoca eludongeni lomthombo, inciphisa ukungeneka kokumila kunye nokunciphisa ilahleko yolwelo kwilitye elijikelezileyo.
   • Ngokulawula ilahleko yolwelo, i-CMC kunye ne-PAC zinceda ukugcina uzinzo lwe-wellbore, ukuthintela umonakalo wokwakheka, kunye nokwandisa ukusebenza kakuhle kokugrumba.
3. Uthintelo lweShale:
   • Kulwakhiwo lwe-shale, i-CMC kunye ne-PAC zinceda ukunqanda ukudumba nokusasazwa kodongwe, ukunciphisa umngcipheko wokungazinzi kwequla kunye neziganeko zokuxinga kwemibhobho.
   • Benza umqobo okhuselayo kumphezulu we-shale, ukuthintela amanzi kunye ne-ion ekusebenziseni iiminerali zodongwe kunye nokunciphisa ukudumba kunye nokusasazeka.
4. Ulwelo oluqhekezayo:
   • I-CMC kunye ne-PAC zikwasetyenziswa kwi-hydraulic fracturing (fracking) ulwelo ukuguqula i-viscosity yolwelo kunye nokumisa amasuntswana axhasayo.
   • Bancedisa ukuthutha i-proppant kwi-fracture kunye nokugcina i-viscosity efunwayo yokubekwa kakuhle kwe-proppant kunye ne-fracture conductivity.

I-sodium carboxymethyl cellulose (CMC) kunye ne-polyanionic cellulose (PAC) zidlala indima ebalulekileyo kwishishini leoli ngokuguqula ukugrumba kunye nokugqiba ulwelo ukufezekisa ukusebenza kakuhle, ukomeleza uzinzo lwe-wellbore, ukulawula ukulahleka kolwelo, kunye nokunciphisa umonakalo wokwakheka. Ukukwazi kwabo ukuguqula iipropathi ze-rheological, inhibit ukudumba kwe-shale, kunye nokumisa amasuntswana angxamisekileyo kubenza babe izongezo eziyimfuneko kwimisebenzi eyahlukeneyo ye-oyile.
