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, olukwaziwa 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 ngokwakha 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 ukuqina koketshezi futhi luvimbele ukuthi lungahlali.

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.
