I-CMC isebenzisa kwi-Petroleum kunye ne-Oil Drilling Industry

I-Carboxymethylcellulose (CMC) isetyenziswa ngokubanzi kwi-petroleum kunye ne-oyile yokugaya imboni yezicelo ezahlukeneyo ngenxa yeempawu zayo ezizodwa njengepolymer e-soluble yamanzi. Ithathwe kwi-cellulose, i-polymer yendalo efunyenwe kwizityalo, ngokusebenzisa inkqubo yokuguqulwa kweekhemikhali eyazisa amaqela e-carboxymethyl. I-CMC iqeshwe kwimisebenzi yokugrumba elunxwemeni nakwi-offshore. Nalu usetyenziso oluninzi olungundoqo lwe-CMC kwishishini le-petroleum kunye ne-oyile yokomba:

1. Drilling Fluid Additive:
   • I-CMC idla ngokusetyenziswa njengesongezo esiphambili kulwelo lokomba. Isebenza ngeenjongo ezininzi, kubandakanya:
     • I-Viscosifier: I-CMC yonyusa i-viscosity yolwelo lokomba, ibonelela ngokuthambisa okuyimfuneko kunye nokunqunyanyiswa kokusikwa.
     • Ukulawulwa kwelahleko yolwelo: I-CMC inceda ukulawula ilahleko yolwelo ekubunjweni kwayo, iqinisekisa ukuzinza kwequla.
     • I-Rheology Modifier: I-CMC isebenza njenge-rheology modifier, echaphazela iipropati zokuhamba kwamanzi okomba phantsi kweemeko ezahlukeneyo.
2. I-Arhente yokunqumamisa:
   • Kwi-drilling fluids, i-CMC isebenza njenge-arhente yokunqunyanyiswa, ikhusela amasuntswana aqinileyo, anjenge-cuttings egrunjiweyo, ekuhlaliseni emazantsi omthombo. Oku kunegalelo ekugrunjweni okusebenzayo kunye nokususwa kwezinto ezisikiweyo kumngxuma wokutsala amanzi.
3. Isinciphisi seLubricant kunye neFriction:
   • I-CMC ibonelela ngokuthambisa kwaye isebenza njengesinciphisi sokukhuhlana kwiincindi zokomba. Oku kubalulekile ekunciphiseni ukukhuhlana phakathi kwendawo yokomba kunye nequla, ukunciphisa ukuguga kwezixhobo zokomba kunye nokuphucula ukusebenza kakuhle kokomba.
4. Ukuzinziswa kweBorehole:
   • I-CMC inceda ukuzinzisa iqula ngokunqanda ukudilika kwezinto ezombiweyo. Yenza isambatho esikhuselayo kwiindonga ze-wellbore, ukuqinisa ukuzinza ngexesha lokusebenza kokumba.
5. ISement Slurry Additive:
   • I-CMC isetyenziswa njenge-additives kwi-slurries yesamente yokufakwa kwe-oyile kumthombo wesamente. Iphucula iimpawu ze-rheological ze-sement slurry, ukuqinisekisa ukubekwa ngokufanelekileyo kunye nokuthintela ukuhlukana kwamacandelo e-samente.
6. UkuBuyiswa kwakhona kwe-Oli (EOR):
   • Kwiinkqubo eziphuculweyo zokubuyisela ioli, i-CMC ingasetyenziswa njenge-arhente yokulawula ukuhamba. Inceda ekuphuculeni ukusebenza kakuhle kokufuduswa kolwelo olutofelweyo, kuququzelela ukubuyiswa kweoyile eyongezelelweyo kwiireservoirs.
7. Ulawulo lweViscosity yolwelo:
   • I-CMC iqeshwe ukulawula i-viscosity ye-drilling fluids, iqinisekisa iipropati zolwelo ezisemgangathweni phantsi kweemeko ezahlukeneyo ze-downhole. Oku kubalulekile ekugcineni ukusebenza kakuhle kokomba kunye nokuzinza kwequla.
8. Ulawulo lweKeyiki yesihluzi:
   • I-CMC inceda ukulawula ukusekwa kweekeyiki zokucoca kwiindonga ze-wellbore ngexesha lokomba. Inegalelo ekudaleni ikeyiki yokucoca ezinzileyo kwaye elawulekayo, ukuthintela ukulahleka kolwelo olugqithisileyo kunye nokugcina ingqibelelo ye-wellbore.
9. IziXhobo Zokugrunjwa Kwidama:
   • Ekugrunjweni kwedama, i-CMC isetyenziselwa ukugrumba ulwelo ukujongana nemingeni ethile ehambelana neemeko zamadama. Inceda ekugcineni uzinzo lwequla kunye nokulawula iimpawu zolwelo.
10. ULahleko loKujikeleza:
    • I-CMC iqeshwe ukulawula imiba elahlekileyo yokujikeleza ngexesha lokomba. Inceda ukutywina kunye nebhulorho izikhewu ekubunjweni, ukuthintela ukulahleka kolwelo lokomba kwiindawo eziqhekezayo okanye eziqhekekileyo.
11. Ulwelo lokuvuselela kakuhle:
    • I-CMC inokusetyenziselwa ulwelo lokuvuselela kakuhle ukomeleza i-viscosity yolwelo kunye nokumisa abaxhasi ngexesha lomsebenzi wokuqhekeka kwe-hydraulic.

Isishwankathelo, i-carboxymethylcellulose (CMC) idlala indima ebalulekileyo kwishishini le-petroleum kunye ne-oyile yokomba, igalelo ekusebenzeni, ukuzinza, kunye nokhuseleko lwemisebenzi yokomba. Iipropati zayo eziguquguqukayo zenza ukuba ibe yinto eyongezelelweyo exabisekileyo kwi-drilling fluids kunye ne-sement slurries, ejongene nemingeni eyahlukahlukeneyo ekuhlangabezwene nayo ekuhloliseni nasekukhutshweni kwemithombo yeoli kunye negesi.
