I-Casing Advancing Systems ODEX 140
I-Eccentric casing drilling system iyindlela yanamuhla ekhethwayo yokumba ezimweni ezinzima zomhlabathi, isibonelo, lapho kunamatshe amatshe noma ukwakheka okuxekethile.I-EDS iyisixazululo esiyonga kakhulu ngoba uphiko lwayo lokuvuselela ngobuhlakani ibhithi liyabuyiswa lingasetshenziswa emgodini olandelayo.Lokhu kuklanyelwe ikakhulukazi izimbobo ezingashoni, njengoba kuvame ukuba njalo ekumbiweni kwemithombo yamanzi, emithonjeni ye-geothermal kanye nomsebenzi wokumboza kancane.I-EDS ilungele izimbobo ezimfushane umthwalo osindayo ohlanganisiwe.Ingxenye yesistimu ye-Eccentric iqukethe ama-Pilot bits, ama-Reamer bits, idivayisi yomhlahlandlela nesicathulo se-casing.
Uma ubhoboza, ibhithi ye-reamer izozungezisa iphumele ngaphandle ukuze ikhulise imbobo eyanele ukuthi ishubhu le-casing lishelele phansi ngemva kwe-reamer.Uma kufinyelelwa ekujuleni okudingekayo, ipayipi lokubhoboza lizobhoboza liye emuva futhi i-reamer bit izohlehla, ivumela lonke uhlelo lokumba ludlule ku-casing.
Usayizi ongezansi wezinhlelo ze-Eccentric ezitholakalayo, kanye nomklamo okhethekile uphezu kwemfuneko yekhasimende:
I-Eccentric 90, i-Eccentric 114, i-Eccentric 140, i-Eccentric 165, i-Eccentric 190 ne-Eccentric 240
Isicelo
- Ukumba umthombo we-Geothermal
- Ukumba umthombo wamanzi
- Uphahla lwamapayipi (umbrella arch drilling)
- Umsebenzi Foundation
- Ukuqinisa

Ukusetshenziswa:
1. Ekubunjweni kwamadwala okungazinzile, i-casing iyadingeka ukulandela.
2. Imvamisa ekubhojweni komthombo wamanzi, ukuze kubhore imbobo enkulu.
3. Ukujula kokumba kungcono ngaphansi kwamamitha angama-40 ukulawula umgodi kahle.
4. Fanisa ku-6" isando kanye neshubhu lebhokisi lebhokisi elingu-194mm.
5. Umfutho womoya ungu-20 Bar kanye nevolumu yomoya engu-500 cfm.
6. Amathuluzi alandwa ukuze asetshenziswe emigodini elandelayo.
