Drilling Fluid Addives | HEC, CMC,PAC

Ukugrumba izongezo zolwelo, kubandakanywa iHEC (i-hydroxyethyl cellulose), i-CMC (i-carboxymethyl cellulose), kunye ne-PAC (i-polyanionic cellulose), zizinto ezibalulekileyo ezisetyenziswa kwishishini leoli kunye negesi ukunyusa ukusebenza kolwelo lokomba. Nantsi inkcazo yeendima zabo kunye nemisebenzi:

1. I-HEC (i-Hydroxyethyl Cellulose):
   • Ukulawulwa kweViscosity: I-HEC yipolymer enyibilikayo emanzini ehlala isetyenziswa njenge-viscosity modifier kwi-drilling fluids. Inceda ukwandisa i-viscosity ye-fluid, ebalulekileyo ekuthwaleni nasekumiseni i-drill cuttings, ngakumbi kumaqula athe nkqo okanye atenxileyo.
   • Ukulawulwa kokuLahlwa kwe-Fluid: I-HEC inokuphinda isebenze njenge-arhente yokulawula ukulahleka kwamanzi, ukunciphisa ukulahlekelwa kwe-drilling fluids ekubunjweni. Oku kunceda ukugcina uzinzo lwe-wellbore kunye nokuthintela umonakalo obiza imali.
   • Ukuzinza kobushushu: I-HEC ibonisa ukuzinza kakuhle kweqondo lokushisa, okwenza kube yinto efanelekileyo yokusetyenziswa kwiindawo zombini zokushisa kunye nokushisa okuphantsi.
   • Isebenzisana kakuhle nokusiNgqongileyo: I-HEC iyabolisa kwaye ihambelana nokusingqongileyo, nto leyo eyenza ibe lolona khetho lukhethwayo lokusetyenziswa kulwelo lokomba, ngakumbi kwiindawo ezinobuthathaka kokusingqongileyo.
2. I-CMC (iCarboxymethyl Cellulose):
   • I-Viscosity Modifier: I-CMC yenye ipholima enyibilikayo emanzini edla ngokusetyenziswa njenge-viscosity modifier kulwelo lokomba. Inceda ekuphuculeni iimpawu rheological ulwelo, iphucula umthamo wayo ethwele kunye nokunqunyanyiswa drill cuttings.
   • Ukulawulwa kwelahleko yolwelo: I-CMC isebenza njengearhente yokulawula ilahleko yolwelo, ukunciphisa ilahleko yolwelo ekubunjweni nasekugcineni uzinzo lwe-wellbore ngexesha lemisebenzi yokomba.
   • Ukunyamezelwa kweTyuwa: I-CMC ibonakalisa ukunyamezela ityuwa elungileyo, iyenza ilungele ukusetyenziswa ekugrumbeni ulwelo kulwakhiwo lwetyuwa okanye apho ubutyuwa obuphezulu budibana khona.
   • Uzinzo lwe-Thermal: I-CMC inozinzo olufanelekileyo lwe-thermal, eyivumela ukuba igcine ukusebenza kwayo nakumaqondo obushushu aphakamileyo adityaniswa kwimisebenzi yokomba enzulu.
3. I-PAC (i-Polyanionic Cellulose):
   • I-Viscosity ephezulu: I-PAC yi-polymer ephezulu ye-molecular-weight ebonelela nge-viscosity ephezulu kwi-drilling fluids. Inceda ukuphucula umthamo wokuthwala ulwelo kwaye inceda ekunqunyanyisweni kokusikwa kwe-drill.
   • Ukulawulwa kwelahleko ye-Fluid: I-PAC yi-arhente esebenzayo yokulawula ilahleko yolwelo, ukunciphisa ilahleko yolwelo ekubunjweni kunye nokugcina uzinzo lwe-wellbore.
   • Uzinzo lobushushu: I-PAC ibonisa uzinzo olubalaseleyo lwe-thermal, iyenza ilungele ukusetyenziswa kwiindawo zokomba ezinobushushu obuphezulu, ezifana namanzi anzulu okanye ukugrumba i-geothermal.
   • Ukonakaliswa koLwakhiwo oluphantsi: I-PAC yenza ikhekhe elicwengekileyo, elingagungqiyo ebusweni bokwakheka, ukunciphisa umngcipheko womonakalo wokwakheka kunye nokuphucula ukusebenza kakuhle.

Ezi zongezelelo zolwelo zokomba, kubandakanywa i-HEC, i-CMC, kunye ne-PAC, zidlala indima ebalulekileyo ekuphuculeni imisebenzi yokomba ngokulawula iipropati zolwelo, ukunciphisa umonakalo wokwenziwa, kunye nokuqinisekisa ukuzinza kwe-wellbore. Ukukhethwa kwabo kunye nokusetyenziswa kwabo kuxhomekeke kwiimeko ezithile zokomba, ezifana neempawu zokubumba, ubunzulu bomthombo, ubushushu, kunye netyuwa.
