Casing Advancing Systems ODEX 140
Eccentric casing drilling system yog niaj hnub no txoj kev nyiam rau drilling hauv av nyuaj, piv txwv li, qhov twg muaj pob zeb los yog xoob formations.EDS yog cov kev daws teeb meem zoo tshaj plaws vim tias nws qhov kev txawj ntse reaming tis lub ntsis yog retrievable siv tau ntawm lub qhov tom ntej.Qhov no yog tshwj xeeb tshaj yog tsim rau cov qhov ntiav ntiav, ib yam li feem ntau cov ntaub ntawv nyob rau hauv dej zoo drilling, geothermal qhov dej thiab rau ntiav micro-piling ua hauj lwm.EDS yog qhov zoo tagnrho rau qhov luv luv hauv kev sib sau ua ke overburden.Cov khoom ntawm Eccentric system muaj xws li Pilot khoom, Reamer khoom, Qhia ntaus ntawv thiab casing khau.
Thaum drilling, lub reamer me ntsis yuav tig tawm kom loj lub qhov uas txaus rau lub casing raj xaub rau hauv qab lub reamer.Thaum ncav cuag qhov xav tau qhov tob, cov yeeb nkab laum yuav laum mus rau qhov kev taw qhia rov qab thiab cov reamer me ntsis yuav thim rov qab, nws tso cai rau tag nrho cov txheej txheem drilling kom dhau los ntawm lub casing.
Cov hauv qab no loj ntawm Eccentric systems uas muaj, thiab cov qauv tsim tshwj xeeb yog raws li cov neeg siv khoom xav tau:
Eccentric 90, Eccentric 114, Eccentric 140, Eccentric 165, Eccentric 190 thiab Eccentric 240
Daim ntawv thov
