Nā ʻōlelo kuhikuhi no ka hoʻohana ʻana i ka bit drill
1 iki koho
1. E ʻoluʻolu e heluhelu pono i ka wehewehe ʻana i ka lithology a me nā moʻolelo bit o nā pūnāwai pili, a me ka nānā ʻana i nā ʻano hana.
2. Ke koho ʻana i ke ʻano kūpono e like me ka lithology.
2 Hoʻomākaukau ma mua o ka wili ʻana
1. E nānā i ka bit mua no ka poino kino, nalowale nā mea ʻoki a i ʻole nā mea hoʻokomo a me nā mea ʻē aʻe.
Pono e mālama pono ʻia ʻo 2.Bit me ka mālama ʻole i nā mea ʻoki a me nā mea paʻakikī.
3. E nānā inā he pōʻino ma nā ʻoki ʻoki a inā he mea ʻē i loko o ka bit.
4. E nānā inā hoʻokomo ka nozzle i nā koi, a hoʻololi i nā nozzles inā pono.
3 Hoailona i ka bit
1. E hoʻomaʻemaʻe i nā lola bit a kau i ka momona ma nā lola.
2. E hoʻopili i ka mea haki i ka bit, e hoʻohaʻahaʻa i ke kaula drill ma luna o ka pine a hoʻopili i nā kaula.
3. Locate i ka bit a me ka breaker i loko o ka rotary bushing, a make-up i ka bit e paipai 'ia torque.
4 Ke hele ʻana i loko
1. Wehe i ka mea uhaki a e hoʻohaʻahaʻa iho i ka bit ma o ke poʻo punawai i ʻole e pōʻino.
2.Shrinkage, poʻohiwi, dogleg a me ka noho kī o ka borehole pono e makaʻala ke nahu ma ka puka hakahaka.
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.
