ʻōnaehana hoʻokele rotary(RSS) he ʻano wiliʻenehanahoʻohana ʻia mawili kuhikuhi. Hoʻohana ia i ka hoʻohana ʻana i nā lako downhole kūikawā e pani i nā mea hana kuhikuhi maʻamau e like menā motika lepo.He hoʻololi nui ia i ka ʻenehana wili kuhikuhi mai ka makahiki 1990.
Loaʻa i ka RSS drilling nā hiʻohiʻona o ka friction haʻahaʻa a me ke kūpaʻa torsional, kiʻekiʻe drilling rate, haʻahaʻa ke kumu kūʻai, pōkole ke kūkulu ʻia ʻana o ka luawai, maʻemaʻe wellbore trajectory, maʻalahi ka mana a me ka hoʻonui ʻana i ka lōʻihi o ka ʻāpana ākea, a me nā mea ʻē aʻe. ʻenehana wili.
Hiki ke hoʻokaʻawale ʻia ka ʻōnaehana hoʻokele rotary i ʻelua ʻano ʻōnaehana e like me kona ʻano alakaʻi: Push the Bit a Point the Bit.
ʻOi aku ma mua o 40% o nā Wells directional o ka honua i wili ʻia me ka hoʻohana ʻana i nā ʻōnaehana hoʻokele rotary, i loaʻa ka pōmaikaʻi o ka mana maoli o ke kuhikuhi ʻana i lalo, e like me ka "3D version of the snake" drilling tool trajectory adjustment. ʻAe kēia i kahi huakaʻi hoʻokahi ma o ka hoʻokumu ʻia ʻana i loko o kahi "ʻekolu-dimensional" wahi - ʻoiai he 0.2 m anawaena bit hiki ke hele ma ka ʻaoʻao a i ʻole ka diagonal ma o kahi waihona wai lahilahi 0.7 m e hoʻokō i kahi huakaʻi "lateral" lōʻihi o 1,000 m i hoʻokahi. huakaʻi.
Ma muli o ke kumukūʻai kiʻekiʻe o ka ʻenehana, ua hana ʻia ka holomua liʻiliʻi ma ka ʻaoʻao haʻahaʻa o ka mākeke wili kuhikuhi. Eia nō naʻe, he waiwai nui ke alakaʻi pololei e hoʻonui ai i ka hoʻohana ʻana i nā kumuwaiwai aila a me ke kinoea.
