ʻO ka nānā ʻana o nā rig luawai wai

I ke kenekulia 2 BC, ua hoʻohana ʻo Kina i ka mana kanaka a ua hoʻohana i ka ikaika elastic bow bow e hoʻopōʻino ai i ka bit cone drill i ka lepo e wili ai.Ma hope mai, ua hoʻohana ʻia ma ke kuaʻāina ʻo Kina no ka manawa lōʻihi.ʻAʻole a hiki i ka makahiki 1950 i hoʻokomo ʻia nā rig wili kaula wili mai waho mai.I nā makahiki 1960, ua hoʻomohala ʻia nā rig wili wai maʻalahi e like me nā ipu hao nui a liʻiliʻi a me nā cones punch-grab.Ma kahi o 1966, ua hoʻomaka ʻia ka hoʻomohala ʻana i ka rig circulation rotary drilling rig, ka reverse circulation rotary drilling rig a me ka pūhui drilling rig i hoʻomohala maikaʻi ʻia a puni 1974, a ua hana ʻia ka down-the-hole vibrating rotary drilling rig i ka hopena o 1970s.Ua hoʻohana nui nā ʻāina ʻEulopa a me ʻAmelika i nā rig wili kaula kaula wili i ke kenekulia 19.I ka makahiki 1860, ua hoʻohana mua ʻo Farani i nā rigs rotary drilling rigs, i hoʻokomo ʻia ma hope aku i ʻAmelika Hui Pū ʻIa a hoʻomohala wikiwiki.I ka makahiki 1950, ua hoʻomaka ka hoʻomohala ʻana i nā rigs rotary rotary drilling reverse-circulation.Ma hope mai, ua hoʻohana ʻia nā rig wili wiliwili e hoʻohana ana i ka ea kōmi ma mua o ka lepo i ka wā i ʻike ʻia ai ka mea holoi wai.I ka makahiki 1970, ua hoʻomohala ʻia nā rigs wili wili hydraulic.
