    3. E hoʻomaka i ka pauma a me ka pōʻaiapuni ʻana i ka wai e holoi i ka puka i ka wā e wili ai i kahi kiko ma kahi o 30 mau mika a lalo o ka lua, a e hoʻohuli i ke kaula drill ma ka māmā haʻahaʻa ʻaʻole i oi aku ma mua o 60rpm

    4. E hoʻokokoke i ka lalo ma kahi o ka hapalua mika.E kaapuni no 5 a 10 mau minuke me ke kahe piha.

    5 ʻO Reaming

    ʻAʻole ʻōlelo ʻia ʻo 1.Reaming ʻāpana lōʻihi o ka lua undergauge.

    2. Inā pono ka hana reaming, pono e hana ʻia ka hana reaming me ka nui o ke kahe kahe o ke kahe, ke kaumaha kikoʻī ma ka bit ʻaʻole iʻoi aku ma mua o 90N/mm (diameter), ʻaʻole i ʻoi aku ka wikiwiki o ka rotary ma mua o 60 rpm kahi i paʻa ai i ka wā e hele ai. i loko.

    6 wahi haʻihaʻi bit

    1.Overusing hōʻike mea kani ke bit approch bottomhole.Inā hoʻonui ka WOB a me ka torque, ua komo ka bit ma lalo. E hoʻohana i ʻoi aku ma mua o 90N/mm, kaumaha –on = bit a me 40 a 60rpm e hoʻokumu i ke kumu o ka bottomhole ma ka hapalua mika.

    Ua hoʻopau ʻia ka 2.Bit break-in a pono e hoʻoponopono ʻia i ka RPM no ka loaʻa ʻana o ka hoʻohui ʻana o nā ʻāpana wili.

    3. Pono e koho ʻia ka hoʻoponopono ʻana i nā palena o ka drilling i loko o nā palena o nā ʻāpana i ʻōlelo ʻia e pili ana i ke ʻano o ka hoʻonui ʻana i nā ʻōkuhi wili.
