I-CMC isebenzisa embonini ye-petroleum ne-oyili yokumba uwoyela

I-Carboxymethylcelcelcellellulose (CMC) isetshenziswa kabanzi embonini ye-petroleum kanye nokushayela kawoyela izicelo ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile njenge-polymer esondelana amanzi. Kuthathwe ku-cellulose, i-polymer yemvelo etholakala ezitshalweni, ngenqubo yokuguqulwa kwamakhemikhali eyethula amaqembu e-carboxymethyl. I-CMC iqashwa emisebenzini yokumba eyokuqala kanye nokudla kwangaphandle. Nakhu ukusetshenziswa okungukhiye okuningana kwe-CMC embonini ye-petroleum ne-oyili yokumba:

1. Ukuvutha uketshezi olungezansi:
   • I-CMC isetshenziswa kakhulu njengesengezo esemqoka ku-dripling fluid. Inika izinhloso eziningi, kufaka phakathi:
     • I-VisCosifier: I-CMC ikhulisa ukubonana koketshezi lokumba, ukuhlinzeka ukuthambisa okudingekayo nokumiswa kwezindawo zokusika.
     • Ukulawulwa kokulahlekelwa yi-Fluid: I-CMC isiza ukulawula ukulahlekelwa koketshezi ekwakhiweni, kuqinisekisa ukuqina komthombo.
     • I-Rheelogy Modifier: I-CMC isebenza njengokushintsha kwe-Rheology, ithonya ukugeleza kwezindawo zoketshezi lokumba ngaphansi kwezimo ezahlukahlukene.
2. Umenzeli wokumiswa:
   • Ku-Drilling Fluids, i-CMC isebenza njenge-ejenti yokumiswa, ivimbela izinhlayiya eziqinile, njengokusika okubanjiwe, kusuka ekuxazululeni phansi komthombo. Lokhu kunomthelela ekubizeni okusebenzayo kanye nokususwa kokusikwa okuvela ku-borehole.
3. Ukugcotshwa nokushayisana nokushayisana:
   • I-CMC inikeza ukuthambisa futhi isebenza njengokunciphisa ukuncipha koketshezi. Lokhu kubalulekile ekunciphiseni ukungezwani phakathi kwe-drill bit kanye ne-borehole, kunciphisa ukugqoka emishini yokumba kanye nokuthuthukisa ukusebenza kahle kokumba.
4. Isilonda seBorehole:
   • I-CMC isiza izinzile i-Wellbore ngokuvimbela ukuwa kwefomu elibiziwe. Kwakha ukuhlanganiswa okuvikelayo ezindongeni ze-Wellbore, kuthuthukisa ukuqina ngesikhathi sokugaya.
5. Usimende Slurry Okweselile:
   • I-CMC isetshenziswa njengesengezo ku-Cement Slurries for uwoyela kahle ukhonkolo. Kuthuthukisa izakhiwo zesimbozo sikasimende Slurry, ukuqinisekisa ukubekwa okufanele nokuvimbela ukuhlukaniswa kwezinto zosethusi.
6. Ukubuyiselwa Kwe-Amafutha Okuthuthukisiwe (Eor):
   • In izinqubo zokubuyisa amafutha ezithuthukisiwe, i-CMC ingasetshenziswa njenge-ejenti yokulawula ukuhamba. Kuyasiza ukuthuthukisa ukusebenza kahle kokuchithwa koketshezi, okwenza ukululama kwamafutha angeziwe kusuka kuma-reservoors.
7. Ukulawulwa kwe-Fluid Viscosity:
   • I-CMC isetshenziswa ukulawula i-viscosity yokuvusa uketshezi, iqinisekise kahle izakhiwo ze-fluid ngaphansi kwezimo ezahlukene zokwehla. Lokhu kubalulekile ukuze ulondoloze ukusebenza kahle kokumba kanye nokuqina komthombo.
8. Isilawuli sekhekhe:
   • I-CMC isiza ukulawula ukwakheka kwamakhekhe okuhlunga ezindongeni ze-Wellbore ngesikhathi sokumba. Inomthelela ekwakhiweni kwekhekhe lokuhlunga elizinzile futhi elilawulayo, ukuvimba ukulahleka kwamanzi ngokweqile kanye nokugcina ubuqotho bempilo.
9. Uketshezi lokumba lwe-Reservoir:
   • Ekuvuthweni kokugcina, i-CMC isetshenziswa kumanzi wokumba ukubhekana nezinselelo ezithile ezihambisana nezimo zezinsalela. Isiza ekugcinweni kokuqina komthombo kanye nokulawula izakhiwo ze-fluid.
10. Ukulawulwa kokusakazwa okulahlekile:
    • I-CMC isetshenziswa ukulawula izindaba ezilahlekile zokujikeleza ngesikhathi sokumba. Kuyasiza ukubekwa uphawu kanye nokuvinjwa kwebhuloho ekwakhekeni, kuvimbela ukulahleka koketshezi lokumba kube yizindawo noma ezikhubazekile.
11. Uketshezi olukhuthaza kahle:
    • I-CMC ingasetjenziswa kumanzi wokukhuthaza kahle ukuze uthuthukise ubuhlakani besenhlamisa abaphuphu ngesikhathi sokuhlaselwa kwe-hydraulic ukuphupha.

Ngamafuphi, i-carboxymethylcellosi (CMC) idlala indima ebalulekile embonini ye-petroleum ne-oyili yokumba embonini, ukuqina ekusebenzeni kahle, ukuqina nokuphepha kokusebenza kokumba. Izakhiwo zayo eziguquguqukayo zikwenza kube yisengezo esibalulekile ekudleni uketshezi kanye nosimende ukuncipha, ukubhekana nezinselelo ezahlukene ezihlangabezana nazo ekuhlolweni nasekukhishweni kwezinsizakusebenza zamafutha negesi.
