I-Polyanionic cellulose eqhelekileyo (PAC-R)

I-olianionic cellulose regular (PAC-R) luhlobo lwe-modified cellulose polymer esetyenziswa kakhulu kwizicelo ezahlukeneyo zoshishino, ingakumbi kwishishini lokugrumba ioyile negesi. Ivela kwi-cellulose yendalo ngokusebenzisa uthotho lotshintsho lweekhemikhali ukunika iipropati ezithile ezifanelekileyo kwizicelo zayo. Nantsi inkcazo-ntetho ye-PAC-R:

1. Isongezo se-Fluid Drilling ye-oyile negesi: I-PAC-R isetyenziswa kakhulu njengesongezelelo solwelo lokugrumba kwishishini leoyile negesi. Isebenza njenge-rheology modifier, i-viscosifier, kunye ne-arhente yokulawula ukuhluza kulwelo lokugrumba olusekelwe emanzini. Ngokulungisa iipropati ze-rheological zolwelo lokugrumba, i-PAC-R inceda ukugcina uzinzo lwe-wellbore, ukulawula ukulahleka kolwelo, kunye nokuphucula ukusebenza kakuhle kokugrumba.
2. Iindawo ezinobushushu obuphezulu kunye netyuwa ephezulu: I-PAC-R ibonakalisa uzinzo kunye nokusebenza kakuhle nakwiindawo zokumba ezinobushushu obuphezulu kunye netyuwa eninzi. Igcina iipropati zayo zokulawula ukulahleka kolwelo kunye nokuxinana phantsi kweemeko ezinzima ezidibana nazo ekumba emanzini anzulu, kwiindawo zokugcina amanzi ezinobushushu obuphezulu, kunye neendawo ezinomxholo wetyuwa ephezulu.
3. Ulawulo lokuhluza: I-PAC-R yenza ikhekhe lesihluzo elincinci, elingangeni manzi eludongeni lwe-wellbor, ivala ngokufanelekileyo ii-permeable formations kwaye ithintele ukulahleka kolwelo kwii-rock structures ezijikelezileyo. Oku kunceda ukugcina uxinzelelo oluqinileyo kwi-wellbor kwaye kuthintela umonakalo kwii-building structure ngexesha lokugrumba.
4. Ukuhambelana nezinye izongezo: I-PAC-R iyahambelana noluhlu olubanzi lwezongezo zolwelo lokubhola, kuquka iipolymers, ii-shale inhibitors, kunye nee-weighting agents. Ingasetyenziswa kunye nezinye izongezo ukuze ilungelelanise iipropati zolwelo lokubhola kwiimeko ezithile ze-wellbore kunye neenjongo zokubhola.
5. Ukuthotyelwa kweMithetho yoBume beNdalo neMigqaliselo: Iifomyula ze-PAC-R zenzelwe ukuhlangabezana neemfuno ezingqongqo zokusingqongileyo kunye nemithetho kwishishini leoyile negesi. Zenzelwe ukunciphisa impembelelo yokusingqongileyo, ukuqinisekisa ukhuseleko lwabasebenzi, kunye nokuthobela imigangatho yolawulo elawula izongezo zolwelo lokumba.

Lilonke, i-PAC-R idlala indima ebalulekileyo ekuphuculeni ukusebenza, ukusebenza kakuhle, kunye nokhuseleko lwemisebenzi yokugrumba kwishishini leoyile negesi. Iimpawu zayo ezikhethekileyo zenza ukuba ibe sisongezelelo esibalulekileyo sokwenza ulwelo lokugrumba oluhlangabezana neemfuno ezifunekayo zemisebenzi yokugrumba yanamhlanje, ingakumbi kwiindawo ezinzima zokugrumba.
