API tricone laum ntsis nqe IADC216 4 5/8 nti (118mm)
Kev piav qhia txog khoom
4 5/8 "TCI tricone ntsis yog siv dav hauv kev khawb dej zoo, kev tshawb nrhiav, HDD pilot qhov, lub hauv paus piling, nws muaj lub hauv paus dav hlau tsim, yog li nws kuj tseem ua haujlwm tau rau kev khawb rov qab.
Cov kabmob raug kaw, lub neej ua haujlwm ntev dua li cov menyuam yaus qhib.
Hom hlau hniav tricone no muaj lub qhov hauv nruab nrab uas tsim nyog rau RC drilling (Reverse Circulation drilling).
IADC216 tricone ntsis tuaj yeem tho qhov nyuaj dua li IADC126, kev xaiv IADC kom raug raws li qhov nyuaj ntawm pob zeb yog thawj kauj ruam ntawm kev ua haujlwm siab. Far Eastern Drilling yog lub Hoobkas API tau ntawv pov thawj ntawm tricone roller bit.
