Iselulosi yeHydroxyethyl kwiDrilling Fluid

I-Hydroxyethyl cellulose (HEC) idla ngokusetyenziswa ekugrumbeni ulwelo lwe-oyile kunye nokuhlolwa kwegesi kunye nokuveliswa. Isebenza ngeenjongo ezahlukeneyo kwaye inikezela ngeenzuzo ezininzi kwesi sicelo. Nantsi indlela iHEC esetyenziswa ngayo kulwelo lokomba:

1. Ulawulo lweRheology: I-HEC isebenza njenge-rheology modifier kwi-drilling fluids, inceda ukulawula i-viscosity yolwelo kunye neempawu zokuhamba. Iphucula isakhono solwelo lokunqumamisa kunye nokuhambisa i-drill cuttings ukuya phezulu, ukuthintela ukuhla kwazo kunye nokugcina uzinzo lwemingxuma.
2. Ukulawulwa koLahleko lwe-Fluid: I-HEC inceda ukunciphisa ilahleko yolwelo olusuka kulwelo lokugrumba lube kwiindlela ezinokungena, ezinokubangela ukungazinzi kunye nomonakalo wokwakheka. Yenza ikeyiki ecekethekileyo, engangenekiyo yokucoca kubuso obubumbayo, inciphisa ilahleko yolwelo lokugrumba kunye nokunciphisa ukungena kwamanzi.
3. Ukucocwa komngxuma: I-HEC inceda ekucoceni imingxuma ngokuphucula umthamo wokuthwala ulwelo lokomba kunye nokuququzelela ukususwa kwe-drill cuttings kumthombo. Iphucula iimpawu zokunqunyanyiswa kolwelo, ukuthintela izinto eziqinileyo ukuba zingahlali kwaye ziqokelele ezantsi komngxuma.
4. Ukuzinza kobushushu: I-HEC ibonisa ukuzinza okuhle kwe-thermal kwaye inokumelana noluhlu olubanzi lwamaqondo okushisa adibana nawo ngexesha lokugaya. Igcina iimpawu zayo ze-rheological kunye nokusebenza njengento edibanisa ulwelo phantsi kweemeko zobushushu obuphezulu, iqinisekisa ukusebenza okuhambelanayo kwiindawo ezicela umngeni.
5. Ukunyamezelwa kweTyuwa: I-HEC iyahambelana ne-salinity ephezulu yokwemba amanzi kwaye ibonisa ukunyamezela ityuwa. Ihlala isebenza njenge-rheology modifier kunye ne-arhente yokulawula ilahleko yolwelo kulwelo lokugrumba oluqulathe ugxininiso oluphezulu lweetyuwa okanye i-brines, eqhele ukuhlangana nemisebenzi yokugrumba kude nonxweme.
6. Isebenzisana kakuhle nokusiNgqongileyo: I-HEC ithathwe kwimithombo ye-cellulose ehlaziyekayo kwaye inobuhlobo nokusingqongileyo. Ukusetyenziswa kwayo kwi-drilling fluids inceda ukunciphisa impembelelo yokusingqongileyo yemisebenzi yokugaya ngokunciphisa ukulahleka kwamanzi, ukuthintela umonakalo wokwakheka, kunye nokuphucula ukuzinza komngxuma.
7. Ukuhambelana neZongezo: I-HEC iyahambelana noluhlu olubanzi lwezongezo zamanzi zokugaya, kubandakanywa i-shale inhibitors, i-lubricants, kunye ne-weighting agents. Inokudityaniswa ngokulula kwimixube yokwemba ulwelo ukufezekisa iimpawu zokusebenza ezinqwenelekayo kunye nokuhlangabezana nemingeni ethile yokomba.

I-Hydroxyethyl cellulose (HEC) iyongezwa kwizinto ezininzi zokugaya amanzi, apho igalelo ekulawuleni i-viscosity, ukulawula ukulahleka kwamanzi, ukucocwa komngxuma, ukuzinza kweqondo lokushisa, ukunyamezela ityuwa, ukugcinwa kwendalo, kunye nokuhambelana nezinye izongezo. Ukusebenza kwayo ekuphuculeni ukusebenza kwe-drilling fluid kwenza kube yinto exabisekileyo kwi-oyile kunye negesi yokuhlola kunye nemisebenzi yokuvelisa.
