Drilling Fluid Additives |HEC, CMC,PAC

Ukumba izithasiselo eziwuketshezi, okuhlanganisa i-HEC (i-hydroxyethyl cellulose), i-CMC (carboxymethyl cellulose), kanye ne-PAC (polyanionic cellulose), izingxenye ezibalulekile ezisetshenziswa embonini kawoyela negesi ukuthuthukisa ukusebenza koketshezi lokumba.Nakhu ukuhlukaniswa kwezindima nemisebenzi yabo:

1. I-HEC (Hydroxyethyl Cellulose):
   • I-Viscosity Control: I-HEC iyi-polymer encibilika emanzini evame ukusetshenziswa njengesilungisi se-viscosity ekubhojweni okuketshezi.Kuyasiza ukukhulisa i-viscosity yoketshezi, okubalulekile ekuthwaleni nasekumiseni ama-drill cuttings, ikakhulukazi emithonjeni eqondile noma ephambukile.
   • Ukulawulwa Kokulahleka Kwe-Fluid: I-HEC ingasebenza futhi njenge-ejenti yokulawula ukulahlekelwa uketshezi, inciphise ukulahlekelwa uketshezi lokumba ekubunjweni.Lokhu kusiza ukugcina ukuzinza kwe-wellbore futhi kuvimbela umonakalo obizayo wokwakheka.
   • Ukuzinza Kwezinga Lokushisa: I-HEC ibonisa ukuzinza okuhle kwezinga lokushisa, okwenza ifanelekele ukusetshenziswa kuzo zombili izindawo zokumba ezisezingeni eliphezulu nezingashisi.
   • Ayinobungane Ezemvelo: I-HEC iyabola futhi ayihambisani nemvelo, okuyenza ibe ukukhetha okuthandwayo ukusetshenziswa ekumba uketshezi, ikakhulukazi ezindaweni ezizwela imvelo.
2. I-CMC (Carboxymethyl Cellulose):
   • I-Viscosity Modifier: I-CMC enye i-polymer encibilika emanzini evame ukusetshenziswa njengesilungisi se-viscosity kuketshezi lokumba.Isiza ukuthuthukisa izakhiwo ze-rheological zoketshezi, ithuthukise umthamo wayo wokuthwala kanye nokumiswa kokusikwa kokubhoboza.
   • Ukulawulwa Kokulahleka Kwe-Fluid: I-CMC isebenza njenge-ejenti yokulawula ukulahlekelwa uketshezi, inciphisa ukulahlekelwa uketshezi ekwakhekeni nokugcina ukuzinza kwe-wellbore ngesikhathi sokumba.
   • Ukubekezelela Usawoti: I-CMC ikhombisa ukubekezelela usawoti okuhle, okuwenza ulungele ukusetshenziswa ekubhojweni koketshezi ekwakhekeni kukasawoti noma lapho kutholakala khona usawoti omningi.
   • Ukuzinza Kwe-Thermal: I-CMC inokuzinza okuhle kokushisa, okuyivumela ukuthi igcine ukusebenza kwayo ngisho nasemazingeni okushisa aphakeme okuhlangatshezwane nawo emisebenzini yokumba ejulile.
3. I-PAC (Polyanionic Cellulose):
   • I-Viscosity Ephakeme: I-PAC iyi-polymer enesisindo esikhulu samangqamuzana enikeza i-viscosity ephezulu kuketshezi lokumba.Isiza ukuthuthukisa umthamo wokuthwala uketshezi futhi isiza ekumisweni kokusikwa kokubhola.
   • Ukulawulwa Kokulahleka Kwe-Fluid: I-PAC iyi-ejenti esebenza kahle yokulawula ukulahlekelwa uketshezi, enciphisa ukulahlekelwa uketshezi ekwakhekeni futhi igcine ukuzinza kwe-wellbore.
   • Ukuzinza Kwezinga Lokushisa: I-PAC ibonisa ukuzinza okuhle kakhulu kwe-thermal, okuyenza ifanelekele ukusetshenziswa ezindaweni zokumba ezinezinga eliphezulu lokushisa, njengamanzi ajulile noma i-geothermal drilling.
   • Ukulimala Kokwakheka Okuphansi: I-PAC yakha ikhekhe lesihlungi elincanyana, elingangeneki ebusweni bokubunjwa, linciphisa ubungozi bokulimala kokwakheka kanye nokwenza ngcono ukukhiqiza kahle.

Lezi zithasiselo zoketshezi lokumba, okuhlanganisa i-HEC, i-CMC, ne-PAC, zidlala indima ebalulekile ekwenzeni imisebenzi yokumba ngokufanele ngokulawula izakhiwo eziwuketshezi, ukunciphisa umonakalo wokwakheka, nokuqinisekisa ukuzinza kwe-wellbore.Ukukhetha nokusetshenziswa kwazo kuncike ezimeni ezithile zokumba, njengezici zokubunjwa, ukujula komthombo, izinga lokushisa, nosawoti.
