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 wili, ʻo nā mea hana wili he mau magnetic a loaʻa kahi pākuʻi magnetic, e pili ana i nā mea ana magnetic a ʻaʻole hiki ke loaʻa 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 drilling. .

Hōʻike ʻia ke kumu hana o ke kola drill non-magnetic ma ke kiʻi. No ka mea, ʻaʻohe hopena o ka laina ma luna a ma lalo o ke kola drill i ka mea ana, ua hana ʻia kahi kaiapuni 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 hao manganese-chromium-nickel home, etc.

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