He aha nā mea hana pono e hoʻohana ʻia no ka ʻeli ʻana i ka geology ikaika

1. Hoʻolako ʻia ka rig drilling me kahi friction a i ʻole interlocking kelly bar, hiki ke hālāwai me ke anawaena o ka puʻu a me ka lōʻihi o ka puʻu.

2. Kelly Bar: koho i ke ʻano o ka paipu drill e like me ka ikaika o ka pōhaku i hoʻomaloʻo ʻia (1 mika pile anawaena, no ka laʻana), ʻoi aku ka haʻahaʻa haʻahaʻa ma mua o 500 kPa me ka friction kelly bar; ʻoi aʻe ma mua o 500 kPa me ka pahu kelly pili.

3. Nā mea hana wili: Hiki ke wili ʻia ka hapa nui o nā pōhaku i hoʻopaʻa ʻia me ka pahu lua lalo o nā niho pōkā; Hiki ke hoʻohana ʻia nā mea hana lua-cone spiral drilling no ka wili maloʻo. Ke piʻi ka mana haʻahaʻa hope loa i 600 kPa-900 kPa, pono e hoʻohana i ka pahu pahu pahu no ka ʻoki apo, akā ʻaʻole hiki ke lawe i nā cores, no laila pono e hoʻohana hou i ka lua lalo lalo.

4. ʻO ka wili ʻana i nā niho: 30/50.22 mm nā niho pōkā a me 4S bullet niho alakaʻi nā niho i hoʻohana ʻia e wili i loko o ka makani ikaika, kahi kūpono i ka ʻoki ʻana, hoʻemi i ke kūʻē ʻana i ka wili, a me ka hoʻohaʻahaʻa pono ʻana i nā poho.
