Isistimu ye-concentric casing

 Isistimu yokubhola eyi-Drill symmetric/Concentric drilling iklanyelwe ukubhoboza nokufaka imbobo ngesikhathi esisodwa ezimweni ezingazinzile zomhlabathi. Ibhithi yomshayeli ehlanganiswe nendandatho eyanelisayo noma indandatho ephinde isetshenziswe yenza idizayini yekhanda eligcwele yobuso ethuthukisa kakhulu izinga lokungena kanye nokuqondisa kwembobo kokumba. Ama-grooves angaphakathi okuguquguqukayo kanye nezicathulo ze-casing ezakhelwe ngaphakathi zinikeza uphawu oluhle enkinobho yembobo yokubhoboza, futhi ngaleyo ndlela kuncishiswe ukuphazamiseka kokuzungezile kwembobo yokubhoboza.

Ibanga Lohlelo:Ilungele ukumba imithombo yamanzi, imithombo ye-geothermal, ama-miscopies amafushane, umgodi wokumba wesakhiwo ophakathi nendawo, iphrojekthi yedamu kanye nechweba.
