I-Concentric Casing System Nge-ring Bit

Incazelo emfushane:

Ukubhoboza amafomethi ngezinto ezixegayo, ezingahlanganisiwe njalo kuza nezinkinga ezifana nokubhoboza imbobo noma ukubhidlika.Indlela yokugwema lezi zinkinga?Ngokuhamba kweminyaka yokuzijwayeza nokucwaninga, sakha isistimu ye-cocentric casing enebhithi yokukhala yezinhlelo zokusebenza ezibanzi kakhulu.Ngokungena okusebenzayo, isistimu ifinyelela ku-casing 100meters, futhi ingasetshenziselwa ukunqwabelanisa isisekelo.

Isinyathelo1:Ukwakhiwa komthwalo phezu komthwalo sekuphelile.

Isinyathelo2:Hlehlisa ukuzungezisa isando bese udonsa kancane umshayeli embobeni.

Isinyathelo sesi-3:Faka esikhundleni ibhithi lokushayela ngebhithi evamile ukuze uqhubeke ubhoboza phansi.
