Zisebenza njani iikhola ze-non-magnetic drill?

1. Umsebenzi wekhola ye-non-magnetic drill

Kuba zonke izixhobo zokulinganisa imagnethi ziva umhlaba we-geomagnetic wequla xa kusenziwa umlinganiselo wokuma wequla, isixhobo sokulinganisa kufuneka sibe kwindawo engeyiyo eyemagnetic.Nangona kunjalo, ngexesha lenkqubo yokomba, izixhobo zokomba zihlala zimagnetic kwaye zinendawo yamagnetic, echaphazela izixhobo zokulinganisa imagnethi kwaye azikwazi ukufumana ulwazi oluchanekileyo lwe-wellbore trajectory.Ukusetyenziswa kwee-collars ze-drill non-magnetic kunokubonelela ngokusingqongileyo okungeyona imagnetic kwaye ibe neempawu ze-drill collars kwi-drilling..

Umgaqo wokusebenza wekhola ye-non-magnetic drill iboniswe kumzobo.Ekubeni imigca yemagnethi yophazamiseko ngaphezulu nangaphantsi kwekhola ye-drill ayinayo impembelelo kwisixhobo sokulinganisa, indawo engeyiyo imagnetic yenzelwe isixhobo sokulinganisa imagnethi, iqinisekisa ukuba idatha elinganiswe ngesixhobo sokulinganisa imagnethi iyinyani.ulwazi lwentsimi ye-geomagnetic.

2. Izixhobo zekhola zokuqhuba i-non-magnetic

Izixhobo zekhola yokugrumba i-non-magnetic ziquka i-Monel alloy, i-chromium-nickel steel, i-austenitic steel esekelwe kwi-chromium kunye ne-manganese, i-alloy ye-copper-plated, i-SMFI non-magnetic steel, intsimbi yasekhaya ye-manganese-chromium-nickel, njl.

I-Landrill inikezela ngee-collars drill kumgangatho kunye ne-spiral ukusuka kwi-3-1 / 8''OD ukuya kwi-14''OD ngokuhambelana ne-API, i-NS-1 okanye i-DS-1.
