Inkqubo ye-concentric casing

 I-Drill symmetric / Inkqubo yokomba ephakathi yenzelwe ukugrumba kunye nokufaka umngxuma ngaxeshanye kwiimeko ezingazinzanga zomhlaba. I-bit yomqhubi idityaniswe neringi eyanelisayo okanye i-ring ephinda isetyenziswe yenza uyilo olupheleleyo lwentloko yobuso ephucula kakhulu izinga lokungena kunye nokuthe ngqo komngxuma wokomba. I-grooves yangaphakathi yokugungxula kunye nezicathulo ze-casing ezakhelwe ngaphakathi zinika isitywina esilungileyo kwiqhosha lomngxuma wokubhoboza, kwaye ngaloo ndlela kuncitshiswe ukuphazamiseka kokujikeleza komngxuma wokugaya.

Uluhlu lweSicelo:Ilungele ukugrumba amaqula amanzi, amaqula e-geothermal, ii-miscopies ezimfutshane, umngxuma wokugrumba ophakathi kwesakhiwo, idama kunye neprojekthi yezibuko.
