E like me kā mākou e ʻike ai, ʻo ke koho ʻana i nā ʻāpana koʻikoʻi o ka rotary drilling rig e hoʻoholo pololei i kona ola lawelawe. No kēia, e hoʻolauna ʻo Sinovo, kahi mea hana wili wili wili, pehea e koho ai i nā bākeke drill.
1. E koho i nā bākeke wili e like me nā kūlana honua
ʻO ka hana nui o karig wili ʻanaʻo ka hana ʻana i puka puka ma ka ʻili, a ʻo ka mea hana he pōhaku. Ma muli o ka liʻiliʻi liʻiliʻi o ka puʻu puʻu i kūkulu ʻia, ua hoʻololi ka pōhaku i ka hoʻololi paʻakikī i ke ʻano, ka nui o ka particle, porosity, cementation, hanana a me ka ikaika compressive ma o ka neʻe tectonic a me ka hana mechanical a me ka hana kemika, no laila ka mea hana o ka rotary drilling rig. paʻakikī loa.
No ka hōʻuluʻulu ʻana, aia nā ʻāpana.
Wahi a lithology, ua māhele ʻia i shale, sandstone, limestone, granite, etc.
Wahi a genesis, hiki ke hoʻokaʻawale ʻia i ka pōhaku magmatic, pōhaku sedimentary a me ka pōhaku metamorphic;
Wahi a nā waiwai mechanical, ua hoʻokaʻawale ʻia i ka paʻa, ka plastic a me ka wehe. No laila pehea e koho ai i ka drill bit e like me nā kūlana hoʻokumu? ʻO kēia ka mea i hoʻolauna ʻia:
(1) Pālolo: koho ʻia ka pahu hoʻoheheʻe rotary me ka lalo hoʻokahi. Inā liʻiliʻi ke anawaena, hiki ke hoʻohana ʻia i ʻelua bākeke a i ʻole ka wili ʻana me ka pā wehe.
(2) Hiki ke hoʻolako ʻia ka ʻōpala, ka ʻili lepo palupalu, ka lepo one a me ka papa ʻiliʻili me ka cementation maikaʻi ʻole a me ka liʻiliʻi liʻiliʻi me ka pahu lua lua lalo.
(3) Paʻa mastic: rotary drilling bākeke me ka lepo lepo hoʻokahi (hoʻokahi a papalua lalo) a i ʻole wili pololei me nā niho bakeke e koho ʻia.
(4) Papa Permafrost: hiki ke hoʻohana ʻia ka bakeke auger pololei a me ka bakeke wili ʻana no ka poʻe me ka liʻiliʻi o ka hau, a hiki ke hoʻohana ʻia ka bit auger conical no ka poʻe me ka nui o ka hau. Pono e hoʻomaopopo ʻia he maikaʻi ka bit auger no ka papa lepo (koe wale ka sludge), akā pono e hoʻohana ʻia me ka ʻole o ka wai o ka lepo e pale aku ai i ka paʻi ʻana ma muli o ka momi.
(5) ʻO nā ʻiliʻili i hoʻopaʻa ʻia a me nā ʻiliʻili a me nā pōhaku i hoʻomaloʻo ʻia: conical spiral bit a me pālua ka lalo rotary drilling bākeke e hoʻolako ʻia (hoʻokahi awa no ka nui ʻāpana nui a me ke awa pālua no ka nui ʻāpana liʻiliʻi)
(6) ʻO ka pōhaku moe: hoʻolako ʻia me ka ʻāpana pahu koho - ʻāpana ʻāpana conical - bākeke wili wili me ka lua lalo, a i ʻole e koho i ka bit spiral pololei - bakeke wili ʻana me ka lalo pālua.
(7) ʻO kahi moe moe liʻiliʻi: ua lako me ka ʻāpana cone barrel coring bit - conical spiral bit - pālua pahu wili ʻana i lalo. Inā ʻoi aku ka nui o ke anawaena, e hoʻohana ʻia ke kaʻina hana wili.
