API 7-1Non-Magnetic Drill Collars for Well Drilling
ʻO nā kola Drill he mau paipu pā mānoanoa i mīkini ʻia mai nā kaola kila paʻa a hana ʻia i nā kikoʻī e hālāwai ai a i ʻole ma mua o nā kikoʻī API.Hōʻike ʻia kā mākou ʻike i nā mea kikoʻī, nā waiwai mechanical, ka mālama wela, ka mīkini a me ka nānā ʻana i kā mākou huahana.Hele mai nā kola wili i nā hoʻolālā slick a spiral me nā hiʻohiʻona hou no ka hana palekana a me ka pilikia ʻole.
