Pehea ka hana ʻana o nā kola drill non-magnetic?

1. Hana o ka non-magnetic drill collar

Ma muli o ka ʻike ʻana o nā mea ana magnetic a pau i ke kahua geomagnetic o ka luawai i ke ana ʻana i ke ʻano o ka luawai, pono ka mea ana i loko o kahi kaiapuni non-magnetic.Eia nō naʻe, i ka wā o ke kaʻina hana ʻana, ʻo nā mea hana wili he mea magnetic a loaʻa kahi pā magnetic, e pili ana i nā mea ana magnetic a ʻaʻole hiki ke kiʻi i ka ʻike ana i ke ana ʻana o ka wellbore trajectory.Hiki i ka hoʻohana ʻana i nā kola drill non-magnetic ke hāʻawi i kahi kaiapuni non-magnetic a loaʻa nā hiʻohiʻona o ka drill collars i ka wili..

Hōʻike ʻia ke kumu hana o ke kola drill non-magnetic ma ke kiʻi.No ka mea, ʻaʻohe hopena o nā laina mākēneki interference ma luna a ma lalo o ke kola drill i ka mea ana, ua hana ʻia kahi ʻāina non-magnetic no ka mea ana magnetic, e hōʻoiaʻiʻo ana i ka ʻikepili i ana ʻia e ka mea ana magnetic.ʻike kahua geomagnetic.

2. Non-magnetic drill collar mea

ʻO nā mea hana kolar drill non-magnetic me Monel alloy, chromium-nickel steel, austenitic steel ma muli o ka chromium a me ka manganese, ke kila keleawe-plated, SMFI non-magnetic steel, ka hale manganese-chromium-nickel steel, etc.

Hāʻawi ʻo Landrill i nā kola drill ma ke ʻano maʻamau a hoʻokaʻawale ʻia mai 3-1 / 8''OD a hiki i 14''OD e like me nā kikoʻī API, NS-1 a i ʻole DS-1.
