I-Sodium Carboxymethylcellulose isebenzisa kwi-Petroleum Industries

Sodium Carboxymethylcellulose(CMC) i-polymer enyibilikayo yamanzi ephuma kwi-cellulose esetyenziswa kuluhlu olubanzi lwamashishini, kuquka i-petroleum. Kushishino lwepetroleum, iCMC isetyenziswa njengesongezo solwelo lokomba, isongezelelo solwelo olugqityiweyo, kunye nesongezo solwelo oluqhekezayo. Iimpawu zayo ezikhethekileyo zenza ukuba ibe yinto ebalulekileyo kwimisebenzi emininzi yokuhlola ioli kunye negesi kunye nemveliso. Eli nqaku liza kuxoxa ngeendlela ezahlukeneyo zokusetyenziswa kwe-CMC kushishino lwepetroleum.

1. Drilling Fluid Additive:

Ulwelo lokugrumba, olukwaziwa njengodaka lokwemba, lusetyenziselwa ukuthambisa kunye nokupholisa intwana yokomba, ukunqumamisa ukusika i-drill, kunye nokulawula uxinzelelo kumthombo. I-CMC isetyenziswa njengesongezo sokwemba ulwelo ukuphucula i-viscosity, ulawulo lokuhluza, kunye neempawu zokuthintela i-shale yodaka lokomba. I-CMC ikwanceda ekunciphiseni ilahleko yolwelo ngokwenza ikeyiki ecekethekileyo, engangenekiyo yokucoca kwiindonga zequla. Oku kunceda ukuthintela ukulahleka kwe-drilling fluid ekubunjweni, okunokubangela umonakalo wokwakheka kunye nokunciphisa imveliso kakuhle.

2. Gqibezela ulwelo loNgezelelweyo:

Ulwelo lokugqibezela lusetyenziselwa ukuzalisa iqula emva kokugrunjwa naphambi kokuveliswa. Ezi ziselo kufuneka zihambelane nokubunjwa kwaye zingonakalisi i-reservoir. I-CMC isetyenziselwa ukugqiba ulwelo lokudibanisa ukulawula i-viscosity kunye neepropati zelahleko zolwelo. Inceda ukuthintela ulwelo ukuba lungavuzi ekubumbeni kwaye lubangele umonakalo.

3. I-fracturing Fluid Additive:

I-Hydraulic fracturing, ekwabizwa ngokuba yi-fracking, bubuchule obusetyenziselwa ukuvuselela ukuveliswa kwe-oyile kunye negesi evela kwi-shale formations. I-Fracturing fluid iphonswa ekubunjweni phantsi koxinzelelo oluphezulu, okwenza ukuba ukubunjwa kuqhekeze kwaye kukhulule ioli kunye negesi. I-CMC isetyenziswa njenge-fracturing fluid additive to improve the viscosity and fluid loss properties of the fluid. Kwakhona kunceda ukumisa iinqununu ezixhaphakileyo, ezisetyenziselwa ukubamba iifractures ezivulekileyo ekubunjweni.

4. Ulawulo lwelahleko yolwelo:

Ilahleko yolwelo yinkxalabo enkulu kumsebenzi wokomba nokugqiba. I-CMC isetyenziswa njenge-arhente yokulawula ilahleko yolwelo ukuthintela ilahleko yokugrumba kunye nokugqiba ulwelo ekubunjweni. Yenza ikeyiki ecekethekileyo, engenakungeneka kwiindonga zequla, enceda ukuthintela ukulahleka kolwelo kunye nomonakalo wokwakheka.

5. Uthintelo lwe-Shale:

I-Shale luhlobo lwelitye eliqhelekileyo lidibana neoli kunye negesi yokuhlola kunye nemisebenzi yokuvelisa. I-Shale inomxholo ophezulu wodongwe, onokubangela ukuba idumbe kwaye ichitheke xa ibonakaliswe kumanzi okugaya amanzi. I-CMC isetyenziswa njenge-arhente yokuthintela i-shale ukukhusela i-shale ekudumbeni nasekuqhekekeni. Yenza umaleko okhuselayo kwiincinci ze-shale, ezinceda ukuzinzisa kunye nokukhusela ukuba zingaphenduli kunye ne-drilling fluid.

6. Isilungisi seRheology:

I-Rheology lufundo lokuhamba kolwelo. I-CMC isetyenziswa njenge-rheology modifier ekwembeni, ukugqitywa, kunye nolwelo oluqhekezayo. Iphucula i-viscosity kunye ne-shear-thinning properties ye-fluid, enceda ukugcina uzinzo lwe-fluid kunye nokukhusela ukuba lungahlali.

7. Isifanisi:

I-emulsion ngumxube wezinto ezimbini ezingenakulinganiswa, ezifana neoli kunye namanzi. I-CMC isetyenziswa njenge-emulsifier kwi-drilling kunye nokugqiba ulwelo ukuzinzisa i-emulsion kunye nokuthintela i-oyile kunye namanzi ekwahlukaneni. Oku kunceda ukuphucula ukusebenza kolwelo kunye nokuthintela umonakalo wokwakheka.

Ukuqukumbela, i-CMC yipolymer eguquguqukayo esetyenziswa kakhulu kushishino lwepetroleum. Iimpawu zayo ezikhethekileyo zenza ukuba ibe yinto ebalulekileyo kwimisebenzi emininzi yokuhlola ioli kunye negesi kunye nemveliso. Isetyenziswa njenge-drilling fluid additive, completion fluid additive, kunye ne-fracturing fluid additive. Ikwasetyenziselwa ukulawula ilahleko yamanzi, inhibition ye-shale, ukuguqulwa kwe-rheology, kunye ne-emulsification.
