ʻOi aku ka nui o ka ROP ma mua o nā pahu drill cone roller
Ke hoʻohālikelike ʻia me nā ʻāpana cone roller, hiki i nā ʻāpana drill hybrid ke hoʻonui i ka ROP, e koi ana i ka liʻiliʻi o ke kaumaha ma ka bit a e hōʻemi i ka bounce bit.
Hoʻohālikelike ʻia ka dinamika drilling i hoʻohālikelike ʻia me PDC
Nā hiʻohiʻona koho
Hoʻohālikelike ʻia me nā PDC, ʻoi aku ka lōʻihi o nā bits hybrid i ka wā e wili ai ma waena o nā hoʻokumu interbedded. Hoʻemi lākou i ka stick-slip a hoʻomaʻamaʻa i ka hoʻokele torque drilling i ka wā e hana like ai ia, e ʻae ana i nā hoʻololi maʻalahi ma o nā ʻano like ʻole. ʻO ka hoʻomaikaʻi ʻana i ke kūpaʻa a me ka hoʻokele kuhikuhi e hiki ai i ka mana kū pololei ʻoi aku ka maikaʻi a me ka nui o ke kūkulu ʻana i nā ʻāpana ma nā ʻāpana pihi.
