I-CMC ne-PAC idlala kanjani indima embonini kawoyela?

I-sodium carboxymethyl cellulose (CMC) kanye ne-polyanionic cellulose (PAC) zombili zisetshenziswa kabanzi embonini kawoyela, ikakhulukazi ekubholeni nasekuqedeni uketshezi. Badlala indima ebalulekile ngenxa yekhono labo lokuguqula izakhiwo ze-rheological, ukulawula ukulahlekelwa koketshezi, nokuthuthukisa ukuzinza kwe-wellbore. Nansi indlela i-CMC ne-PAC esetshenziswa ngayo embonini kawoyela:

1. Ukubhoboza Izithako Zoketshezi:
   • I-CMC kanye ne-PAC zivame ukusetshenziswa njengezithasiselo kuketshezi lokumba olusekelwe emanzini ukulawula izakhiwo ze-rheological ezifana ne-viscosity, iphuzu lesivuno, nokulahlekelwa uketshezi.
   • Zisebenza njengama-viscosifiers, zikhulisa i-viscosity yoketshezi lokumba ukuze kuthuthwe i-drill cuttings phezulu futhi igcine ukuqina kwe-wellbore.
   • Ukwengeza, asiza ukulawula ukulahlekelwa uketshezi ngokwenza ikhekhe lesihlungi elincanyana, elingangeneki odongeni lomthombo, ehlise ukulahlekelwa uketshezi ekwakhekeni okungenekayo nokugcina ingcindezi ye-hydrostatic.
2. Ukulawula Ukulahleka Kwe-Fluid:
   • I-CMC kanye ne-PAC ama-ejenti asebenzayo okulawula ukulahlekelwa uketshezi kuketshezi lokumba. Zakha ikhekhe lesihlungi elincanyana, eliqinile odongeni lomthombo, linciphisa ukungeneka kokubunjwa kanye nokunciphisa ukulahlekelwa uketshezi edwaleni elizungezile.
   • Ngokulawula ukulahleka koketshezi, i-CMC ne-PAC zisiza ukugcina ukuzinza kwe-wellbore, ukuvimbela ukulimala kokwakheka, nokuthuthukisa ukusebenza kahle kokumba.
3. I-Shale Inhibition:
   • Ekwakhekeni kwe-shale, i-CMC kanye ne-PAC zisiza ukuvimbela ukuvuvuka nokuhlakazeka kobumba, kwehlise ingcuphe yokungaqini kahle kwe-wellbore kanye nezigameko zamapayipi abhajwe.
   • Zakha umgoqo ovikelayo endaweni ye-shale, evimbela amanzi nama-ion ukuthi ahlangane namaminerali obumba futhi anciphise ukuthambekela kokuvuvukala nokuhlakazeka.
4. I-Fluid Fluids:
   • I-CMC ne-PAC nazo zisetshenziswa kuketshezi lwe-hydraulic fracturing (fracking) ukuze kulungiswe i-viscosity yoketshezi nokumisa izinhlayiya ezikhulayo.
   • Zisiza ukuthutha i-proppant ekuqhekekeni futhi zigcine i-viscosity oyifunayo ukuze kufakwe i-proppant ephumelelayo kanye nokuhanjiswa kwe-fracture.

I-sodium carboxymethyl cellulose (CMC) kanye ne-polyanionic cellulose (PAC) zidlala indima ebalulekile embonini kawoyela ngokulungisa uketshezi lokumba nokuqeda ukuze kuzuzwe ukusebenza kahle, kuthuthukiswe ukuzinza kwe-wellbore, ukulawula ukulahlekelwa uketshezi, kanye nokunciphisa ukulimala kokwakheka. Ikhono labo lokuguqula izakhiwo ze-rheological, ukuvimbela ukuvuvukala kwe-shale, nokumisa izinhlayiya ezikhuthazayo kubenza babe izithasiselo ezibalulekile ekusebenzeni okuhlukahlukene kwendawo kawoyela.
