I ka hana ana o ka wili wiliwili, aia mau kekahi sediment ma lalo o ka lua, he hemahema hiki ole ke pale ia o ka wili wiliwili.No laila, no ke aha he sediment ma lalo o ka lua?ʻO ke kumu nui he ʻokoʻa kāna kaʻina hana.Hoʻohana ka rotary drilling rig i ke ʻano hoʻoheheʻe lepo ʻole, a ʻaʻole hiki ke lawe ʻia ka palau wili ʻana i ka lepo ma ke kahe ʻana o ka lepo e noho i lalo.
ʻO kēia nā kumu nui o ka ulu ʻana o ka sediment:
1. Ke koena ma waena o nā niho bakeke o ka wili wili ʻana a me ka uhi lalo o ka bakeke wili.
2. ʻO nā niho o nā rigs wili liʻiliʻi he liʻiliʻi, no laila ʻaʻole hiki ke ʻae ʻia ka sediment ma waena o nā niho;
3. ʻAʻole paʻa paʻa ka uhi lalo o ka mea hana wili;
4. ʻAʻole hiki i ka lepo i ʻoki ʻia mai ka ʻaoʻao o waho o ka pahu hoʻoheheʻe rotary ʻaʻole hiki ke komo i ka waha cylinder ma muli o ka palahalaha lalo o ka lua a noho mau ma ka lihi o lalo o ka lua;
5. I ka ʻeli ʻana i ke one lepo a me ka hoʻoheheʻe ʻana i ka wai, ua nalowale ka wili ʻana i loko o ka pahu drill i ka wā o ka hāpai ʻana, a i kekahi manawa ua nalowale nā mea a pau i loko o ka lua;
6. ʻO ka hoʻihoʻi ʻana o ka pahu drill he nui loa, ua piha ka ukana, a ʻoki ʻia ka ʻōpala mai ka lua wai o ka uhi luna.
Wahi a ke kūlana aupuni, ʻaʻole ʻoi aku ka mānoanoa o ka sediment ma lalo o ka lua no ka puʻu hakakā a me ka puʻu hopena hope ʻaʻole i ʻoi aku ma mua o 100mm a ʻaʻole ʻoi aku ma mua o 50mm.
ʻO nā kumu ma luna aʻe ke kumu o ka loaʻa ʻana o ka lepo i loko o ka hoʻokumu ʻia ʻana o nā lua o nā rig wili liʻiliʻi liʻiliʻi i hōʻuluʻulu ʻia e Gookma.ʻOiai he hemahema hiki ʻole kēia o nā rigs wili liʻiliʻi, ʻo nā mīkini wili wili ʻo ia ka mīkini kūpono loa no ka wili ʻana a me ka pilang i kēia pae.
Ma hope o ka hoʻoheheʻe ʻia ʻana o ka lua, pono mākou e hoʻomaʻemaʻe i ka lua, i hiki ke wehe ʻia ka sediment ma lalo o ka lua.
