Hoobkas ntawm cov roj zoo tricone laum ntsis hauv Tshuag nrog tus nqi luv nqi
IADC: 115 yog cov hlau hniav kaw cov menyuam bearing ntsis nrog gauge tiv thaiv rau cov formations mos nrog lub zog compressive qis.
Lub zog Compressive ntawm IADC115 ntsis cov ntsiab lus yog raws li nram no:
0-35 MPA/ 0-5,000 PSI
Kev piav qhia hauv av:
Lub IADC115 tricone ntsis yog tsim rau cov pob zeb mos, tsis zoo compacted thiab unstratifield xws li marl limestones, ntsev, gypsum, thiab cov thee tawv, tsis zoo compacted av nplaum thiab sandstones,
Cov ntsis tricone muaj hom Tungsten Carbide Insert (TCI) thiab Mill Tooth (Steel Tooth) raws li cov ntaub ntawv txiav.
Lawv muaj ntau yam thiab tuaj yeem txiav ntau hom pob zeb. Lub pob zeb tricone siv rau cov pob zeb mos. Cov pob zeb TCI rotary tricone siv rau cov pob zeb nruab nrab thiab tawv. Cov pob zeb mos suav nrog cov xuab zeb tsis sib xyaw, av nplaum, pob zeb limestones mos, pob zeb liab thiab shale. Cov pob zeb nruab nrab tawv suav nrog dolomites, limestones, thiab shale tawv, thaum cov pob zeb tawv suav nrog shale tawv, thaum cov pob zeb tawv suav nrog shale tawv, av nkos, pob zeb limestones cherty thiab cov pob zeb tawv thiab abrasive.
