ISodium Carboxymethylcellulose isetyenziswa kwiPetroleum Industries

I-Sodium carboxymethylcellulose (CMC) inezicelo ezininzi ezibalulekileyo kwishishini lepetroleum, ngakumbi kulwelo lokomba kunye neenkqubo zokuphucula ioyile. Nalu olunye usetyenziso olungundoqo lwe-CMC kwizicelo ezinxulumene nepetroleum:

1. Ulwelo loKwemba:
   • Ukulawulwa kweViscosity: I-CMC yongezwa kwi-drilling fluids ukulawula i-viscosity kunye nokuphucula iimpawu ze-rheological. Inceda ukugcina i-viscosity efunwayo yolwelo lokomba, olubalulekileyo ekuthwaleni i-drill cuttings phezulu kunye nokuthintela ukuwa kwequla.
   • Ulawulo lwelahleko yolwelo: I-CMC isebenza njengearhente yokulawula ilahleko yolwelo ngokwenza ikeyiki ecekethekileyo, engenamanzi yokucoca eludongeni lomthombo. Oku kunceda ukunciphisa ukulahlekelwa kwamanzi ekubunjweni, ukugcina uzinzo lwe-wellbore, kunye nokuthintela umonakalo wokwakheka.
   • I-Shale Inhibition: I-CMC inqanda ukudumba kwe-shale kunye nokusasazeka, okunceda ukuzinzisa ukwakheka kwe-shale kunye nokuthintela ukungazinzi kwe-wellbore. Oku kubaluleke kakhulu ekubunjweni okunomxholo ophezulu wodongwe.
   • Ukunqunyanyiswa kunye noThutho lwe-Fluid: I-CMC iphucula ukunqunyanyiswa kunye nokuthuthwa kwezinto ezisikiweyo zokomba kulwelo lokomba, ukuthintela ukuhlaliswa kunye nokuqinisekisa ukususwa ngokufanelekileyo kumthombo. Oku kunceda ukugcina ukucoceka kwe-wellbore kwaye kuthintele umonakalo wesixhobo.
   • Iqondo lobushushu kunye noZinzo lweSalinity: I-CMC ibonisa uzinzo olulungileyo kuluhlu olubanzi lwamaqondo obushushu kunye namanqanaba etyuwa adityaniswe nawo kwimisebenzi yokugrumba, iyenza ilungele ukusetyenziswa kwiindawo ezahlukeneyo zokomba.
2. UkuBuyiswa kwakhona kwe-Oli (EOR):
   • Ukukhukula kwamanzi: I-CMC isetyenziselwa imisebenzi yokukhukula kwamanzi njenge-arhente yokulawula ukushukuma ukuphucula ukusebenza kakuhle kokutshayela kwamanzi atofwayo kunye nokuphucula ukubuyiswa kweoli kwiidama. Inceda ukunciphisa umjelo wamanzi kunye neminwe, iqinisekisa ukufuduswa okufanayo kweoli.
   • Izikhukula zePolymer: Kwiinkqubo zokukhukula kwepolymer, i-CMC ihlala isetyenziswa njenge-arhente etyebisayo idityaniswe nezinye iipolymers ukunyusa i-viscosity yamanzi atofwayo. Oku kuphucula ukusebenza kakuhle kokutshayela kunye nokusebenza kakuhle kokufuduswa, okukhokelela kumazinga aphezulu okubuyisela ioyile.
   • Ukuguqulwa kweProfayili: I-CMC ingasetyenziselwa unyango lokuguqulwa kweprofayili ukuphucula ukuhamba kwamanzi phakathi kwamadama. Inceda ukulawula ukushukuma kolwelo kunye nokuhamba kwakhona ukuhambisa ukuya kwiindawo ezingatshayelwayo kancinci, ukonyusa imveliso ye-oyile kwiindawo ezingasebenzi kakuhle.
3. Ulwelo lokuSebenza kunye nokuQeda:
   • I-CMC yongezwa kwi-workover kunye nokugqiba ulwelo ukunika ulawulo lwe-viscosity, ulawulo lwelahleko yolwelo, kunye neempawu zokunqunyanyiswa. Inceda ukugcina uzinzo lwe-wellbore kunye nokucoceka ngexesha lemisebenzi yokusebenza kunye nemisebenzi yokugqiba.

I-sodium carboxymethylcellulose idlala indima ebalulekileyo kwiinkalo ezahlukeneyo zokuhlola i-petroleum, ukugrumba, ukuvelisa, kunye neenkqubo zokuphucula i-oyile. Ukuguquguquka kwayo, ukusebenza kakuhle, kunye nokuhambelana nezinye izongezo kuyenza ibe licandelo elixabisekileyo le-drilling fluids kunye nonyango lwe-EOR, igalelo ekusebenzeni ngokufanelekileyo kunye neendleko ezisebenzayo zepetroleum.
