I-Sodium Carboxymethylcellulose isebenzisa ezimbonini zePetroleum

I-Sodium Carboxymethylcellulose(CMC) i-polymer encibilika emanzini etholakala ku-cellulose esetshenziswa ezinhlobonhlobo zezimboni, kuhlanganise ne-petroleum.Embonini ye-petroleum, i-CMC isetshenziswa njengesengezo soketshezi lokumba, isithasiselo soketshezi lokuphothula, kanye nesengezo se-fracturing fluid.Izakhiwo zayo eziyingqayizivele ziyenza ibe yingxenye ebalulekile emisebenzini eminingi yokuhlola nokukhiqiza uwoyela negesi.Lesi sihloko sizoxoxa ngokusetshenziswa okuhlukahlukene kwe-CMC embonini ye-petroleum.

1. Isengezo se-Drilling Fluid:

Uketshezi lokumba, okwaziwa nangokuthi udaka lokumba, lusetshenziselwa ukugcoba nokupholisa i-drill bit, ukumisa ukusikwa kokubhoboza, nokulawula ukucindezela emgodini womthombo.I-CMC isetshenziswa njengesengezo soketshezi lokumba ukuze kuthuthukiswe i-viscosity, ukulawulwa kokuhlunga, kanye nezakhiwo zokuvinjwa kwe-shale zodaka lokumba.I-CMC iphinde isize ekwehliseni ukulahleka koketshezi ngokwenza ikhekhe lesihlungi elincanyana, elingangeneli ezindongeni zomthombo.Lokhu kusiza ukuvimbela ukulahlekelwa uketshezi lokumba ekubunjweni, okungabangela ukulimala kokwakheka nokunciphisa ukukhiqiza kahle.

2. Isengezo Sokuqeda Uketshezi:

Uketshezi lokuphothula lusetshenziselwa ukugcwalisa umthombo emva kokumba nangaphambi kokukhiqiza.Lawa manzi kufanele ahambisane nokwakheka futhi angalimazi idamu.I-CMC isetshenziswa njengesengezo soketshezi lokuphothula ukulawula i-viscosity kanye nezakhiwo zokulahlekelwa uketshezi loketshezi.Kuyasiza ukuvimbela uketshezi ukuthi lungangeni ekwakhekeni futhi ludale umonakalo.

3. Isengezo se-Fluid Fracturing:

I-Hydraulic fracturing, eyaziwa nangokuthi i-fracking, iyindlela esetshenziselwa ukugqugquzela ukukhiqizwa kukawoyela negesi kusuka ekwakhekeni kwe-shale.I-Fracturing fluid iphonswa ekubunjweni ngaphansi kwengcindezi ephezulu, okwenza ukubunjwa kuphule futhi kukhulule uwoyela negesi.I-CMC isetshenziswa njengesengezo se-fracturing fluid ukuze kuthuthukiswe i-viscosity kanye nezakhiwo zokulahlekelwa uketshezi loketshezi.Kuyasiza futhi ukumisa izinhlayiya ezikhuthazayo, ezisetshenziselwa ukubamba ukuvula ama-fractures ekubunjweni.

4. Ukulawula Ukulahleka Kwe-Fluid:

Ukulahlekelwa uketshezi kuyinkinga enkulu emsebenzini wokumba nokuqeda.I-CMC isetshenziswa njenge-ejenti yokulawula ukulahlekelwa uketshezi ukuze kuvinjelwe ukulahleka kokumba nokuqeda uketshezi ekwakhekeni.Yakha ikhekhe lesihlungi elincanyana, elingenakunyakaziswa ezindongeni zomthombo, okusiza ukuvimbela ukulahlekelwa uketshezi kanye nokulimala kokwakheka.

5. I-Shale Inhibition:

I-Shale wuhlobo lwetshe oluvame ukuhlangana nalo ekuhloleni uwoyela negesi kanye nemisebenzi yokukhiqiza.I-Shale inobumba oluningi, olungabangela ukuthi ikhukhumale futhi ihlakazeke lapho ibhekene noketshezi lokumba olusekelwe emanzini.I-CMC isetshenziswa njenge-ejenti yokuvimbela i-shale ukuvimbela i-shale ukuthi ingavuvukali futhi ihlakazeke.Yakha ungqimba oluvikelayo ezinhlayiyeni ze-shale, okusiza ukuzinzisa nokuzivimbela ekuphenduleni uketshezi lokubhoboza.

6. I-Rheology Modifier:

I-Rheology yisifundo sokugeleza koketshezi.I-CMC isetshenziswa njengesilungisi se-rheology ekubholeni, ekuqedeni, nasekuqhekekeni kwamanzi.Ithuthukisa i-viscosity kanye nezindawo zokunciphisa i-shear-thinning yoketshezi, okusiza ukugcina ukuzinza koketshezi futhi kuvimbele ekuzinzeni.

7. I-Emulsifier:

I-emulsion iyinhlanganisela yoketshezi olubili olungaguquki, njengamafutha namanzi.I-CMC isetshenziswa njenge-emulsifier ekubholeni nasekuqedeni uketshezi ukuze kuqiniswe i-emulsion futhi kuvimbele uwoyela namanzi ukuthi ahlukane.Lokhu kusiza ukuthuthukisa ukusebenza koketshezi futhi kuvimbele ukulimala kokubunjwa.

Sengiphetha, i-CMC iyi-polymer eguquguqukayo esetshenziswa kabanzi embonini ye-petroleum.Izakhiwo zayo eziyingqayizivele ziyenza ibe yingxenye ebalulekile emisebenzini eminingi yokuhlola nokukhiqiza uwoyela negesi.Isetshenziswa njengesengezo se-drilling fluid, i-completion fluid additive, kanye nesengezo se-fracturing fluid.Iphinde isetshenziselwe ukulawula ukulahlekelwa uketshezi, inhibition shale, rheology ukuguqulwa, futhi emulsification.
