Ukusetshenziswa kwe-CMC embonini ye-Petroleum kanye ne-Oyili

I-Carboxymethylcellulose (CMC) isetshenziswa kabanzi embonini yokumba uphethiloli kanye namafutha ngezinhlelo ezahlukene ngenxa yezakhiwo zayo ezihlukile njenge-polymer encibilika emanzini. Itholakala ku-cellulose, i-polymer yemvelo etholakala ezitshalweni, ngenqubo yokuguqulwa kwamakhemikhali eyethula amaqembu e-carboxymethyl. I-CMC isetshenziswa kokubili emisebenzini yokumba ogwini kanye nolwandle. Nazi izindlela eziningana eziyinhloko zokusebenzisa i-CMC embonini yokumba uphethiloli kanye namafutha:

1. Isengezo Sokubhoboza Uketshezi:
   • I-CMC ivame ukusetshenziswa njengesithako esiyinhloko koketshezi lokubhoboza. Isebenza ngezinjongo eziningi, okuhlanganisa:
     • I-Viscosifier: I-CMC yandisa ubulukhuni boketshezi lokubhoboza, ihlinzeka ngokugcotshwa okudingekayo kanye nokumiswa kwezicucu.
     • Ukulawulwa Kokulahlekelwa Uketshezi: I-CMC isiza ukulawula ukulahleka koketshezi ekwakhekeni, iqinisekisa ukuqina komgodi ogelezayo.
     • I-Rheology Modifier: I-CMC isebenza njenge-rheology modifier, ithonya izakhiwo zokugeleza koketshezi lokubhoboza ngaphansi kwezimo ezahlukene.
2. I-ejenti Yokumiswa:
   • Kuketshezi lokubhoboza, i-CMC isebenza njenge-suspension agent, ivimbela izinhlayiya eziqinile, njengezicucu ezibhoboziwe, ukuthi zingahlali phansi komgodi womthombo. Lokhu kunegalelo ekubhobozeni okuphumelelayo kanye nokususwa kwezicucu emgodini womthombo.
3. Isithambisi Sokuthambisa Nokunciphisa Ukungqubuzana:
   • I-CMC inikeza ukuthambisa futhi isebenza njengokunciphisa ukungqubuzana koketshezi lokubhoboza. Lokhu kubalulekile ekunciphiseni ukungqubuzana phakathi kwe-drill bit kanye ne-borehole, kunciphisa ukuguguleka kwemishini yokubhoboza kanye nokuthuthukisa ukusebenza kahle kokubhoboza.
4. Ukuqina Kwemigodi:
   • I-CMC isiza ekuqiniseni imbobo yomthombo ngokuvimbela ukubhidlika kwezakhiwo ezibholiwe. Yakha ungqimba oluvikelayo ezindongeni zembobo yomthombo, okuthuthukisa ukuzinza ngesikhathi sokubhoboza.
5. Isithasiselo se-Siment Slurry:
   • I-CMC isetshenziswa njengesithasiselo kuma-slurry esimende ukuze kuqiniswe ugesi emthonjeni kawoyela. Ithuthukisa izakhiwo ze-rheological ze-slurry yesimende, iqinisekisa ukubekwa kahle futhi ivimbele ukuhlukaniswa kwezingxenye zesimende.
6. Ukuvuselelwa Kwamafutha Okuthuthukisiwe (i-EOR):
   • Ezinqubweni zokubuyisa uwoyela ezithuthukisiwe, i-CMC ingasetshenziswa njenge-ejenti yokulawula ukuhamba. Isiza ekuthuthukiseni ukusebenza kahle kokufuduka koketshezi olujovwe, okwenza kube lula ukubuyisa uwoyela owengeziwe ezindaweni zokugcina amanzi.
7. Ukulawulwa Kokugoba Koketshezi:
   • I-CMC isetshenziswa ukulawula ukujiya koketshezi lokubhoboza, iqinisekisa izakhiwo zoketshezi ezifanele ngaphansi kwezimo ezahlukene zomgodi ophansi. Lokhu kubalulekile ekugcineni ukusebenza kahle kokubhoboza kanye nokuqina kwemigodi.
8. Ukulawula Ikhekhe Lokuhlunga:
   • I-CMC isiza ukulawula ukwakheka kwamakhekhe okuhlunga ezindongeni zemigodi ngesikhathi sokubhoboza. Isiza ekudalweni kwekhekhe lokuhlunga elizinzile nelilawulekayo, ivimbela ukulahleka koketshezi okweqile kanye nokugcina ubuqotho bemigodi yemigodi.
9. Uketshezi Lokubhoboza Echibini:
   • Ekubholeni emachibini, i-CMC isetshenziswa ekubholeni uketshezi ukuze ibhekane nezinselele ezithile ezihambisana nezimo zamachibi. Isiza ekugcineni ukuzinza kwe-wellbor kanye nokulawula izakhiwo zoketshezi.
10. Ukulawulwa Kokuvuza Kokujikeleza Kwegazi:
    • I-CMC isetshenziswa ukulawula izinkinga zokujikeleza kwegazi ezilahlekile ngesikhathi sokubhoboza. Isiza ukuvala nokuvala izikhala ekwakhekeni, ivimbele ukulahleka koketshezi lokubhoboza ezindaweni ezinezimbobo noma eziqhekekile.
11. Uketshezi Lokuvuselela Umthombo:
    • I-CMC ingasetshenziswa eziphuzweni ezivuselela imithombo ukuze kuthuthukiswe ukujiya koketshezi kanye nama-spensers alengayo ngesikhathi sokusebenza kwe-hydraulic fracturing.

Ngamafuphi, i-carboxymethylcellulose (CMC) idlala indima ebalulekile embonini yokumba uphethiloli kanye nowoyela, inikela ekusebenzeni kahle, ekuzinzeni, nasekuphepheni kwemisebenzi yokumba. Izakhiwo zayo eziguquguqukayo ziyenza ibe yisithako esibalulekile koketshezi lokumba kanye nodaka lukasimende, ibhekana nezinselele ezahlukahlukene ezihlangatshezwana nazo ekuhlolweni nasekukhishweni kwezinsizakusebenza zikawoyela negesi.
