ʻO ka rig wili he ʻōnaehana hoʻohui ʻia e wili ai i nā luawai, e like me ka ʻaila a i ʻole nā pūnāwai kinoea, ma lalo o ka honua.
Hiki i nā rig wili ke hana nui i nā lako hale i hoʻohana ʻia e wili ai i nā luawai aila, a i ʻole nā luawai hoʻoheheʻe kinoea maoli, hiki i nā rigs drill ke hōʻike i nā waihona mineral subsurface, ka pōhaku hoʻāʻo, ka lepo a me nā waiwai kino wai, a hiki ke hoʻohana ʻia e hoʻokomo i nā mea hana sub-surface, e like me e like me nā mea hana ma lalo o ka honua, nā mea kani, nā tunnels a i ʻole nā luawai. Hiki i nā rig wili ke lilo i mea kelepona i kau ʻia ma luna o nā kaʻa kaʻa, nā kaʻa a i ʻole nā mea kaʻa, a i ʻole nā ʻāina mau a i ʻole nā hale kai (e like me nā paepae aila, i kapa ʻia ʻo 'offshore oil rigs' inā ʻaʻole i loaʻa kahi rig wili).
ʻO nā rigs wili liʻiliʻi a liʻiliʻi he mobile, e like me nā mea i hoʻohana ʻia i ka ʻeli ʻana o ka mineral, blast-hole, nā pūnāwai wai a me nā noiʻi kaiapuni. Hiki i nā rigs nui ke wili i loko o nā kaukani mika o ka ʻōpala o ka Honua, me ka hoʻohana ʻana i nā "puʻu lepo" nui e kaʻapuni i ka lepo wili (slurry) ma o ka drill bit a piʻi i luna o ka casing annulus, no ka hoʻomaha ʻana a me ka wehe ʻana i nā "ʻoki" i ka wā e hoʻoheheʻe ʻia ai ka pūnāwai. wili ʻia.
Hiki i nā hoists i ka rig ke hāpai i nā haneli haneli o ka paipu. Hiki i nā mea hana ʻē aʻe ke hoʻoikaika i ka waika a i ʻole ke one i loko o nā waihona no ka hoʻomaʻamaʻa ʻana i ka ʻaila a i ʻole ke kinoea maoli; a ma nā wahi mamao hiki ke noho mau a me ka mālama ʻana i nā luina (ʻoi aku paha ma mua o hoʻokahi haneli).
Hiki i nā rigs waho ke holo i mau tausani mile ka mamao mai ke kahua lako me ka hoʻololi pinepine ʻana a i ʻole ka pōʻai.
Hiki iā mākou ke hoʻolako i nā rigs drilling mai 500-9000 mika ka hohonu, i alakaʻi ʻia e ka papa ʻaina rotary a me ka ʻōnaehana hoʻokele kiʻekiʻe, Me ka skid mounted rig, track mounted rig, workover rig a me waho o ka rig.
