Asebenza kanjani amakholomu okubhoboza okungewona uzibuthe?

1. Umsebenzi we-non-magnetic drill collar

Njengoba wonke amathuluzi okulinganisa kazibuthe ezwa inkambu ye-geomagnetic yomthombo womthombo lapho ikala umumo womthombo, ithuluzi lokulinganisa kufanele libe sendaweni engeyona enozibuthe.Kodwa-ke, phakathi nenqubo yokumba, amathuluzi okumba avame ukuba kazibuthe futhi anendawo kazibuthe, ethinta amathuluzi okulinganisa kazibuthe futhi awakwazi ukuthola ulwazi olulungile lwesilinganiso somzila we-wellbore.Ukusetshenziswa kwamakholomu okubhoboza okungewona uzibuthe kunganikeza indawo engeyona enozibuthe futhi ibe nezici zamakholomu okubhoboza ekubholeni..

Umgomo wokusebenza wekhola yokubhoboza i-non-magnetic uboniswa esithombeni.Njengoba imigqa yakazibuthe ephazamisayo ngenhla nangaphansi kwekhola yokubhoboza ingenawo umthelela ethuluzini lokulinganisa, indawo engeyona enozibuthe iyadalelwa ithuluzi lokulinganisa kazibuthe, iqinisekisa ukuthi idatha elinganiswa ithuluzi lokulinganisa kazibuthe iyiqiniso.ulwazi lwensimu ye-geomagnetic.

2. Izinto zekhola yokubhoboza okungezona uzibuthe

Izinto zekhola yokubhola okungezona uzibuthe zifaka ingxubevange ye-Monel, insimbi ye-chromium-nickel, insimbi ye-austenitic esekelwe ku-chromium ne-manganese, ingxubevange ye-copper-plated, i-SMFI non-magnetic steel, insimbi yasekhaya ye-manganese-chromium-nickel, njll.

I-Landrill enikezela ngamakholomu okubhoboza asezingeni futhi asontekile ukusuka ku-3-1/8''OD kufika ku-14''OD ngokuvumelana ne-API, NS-1 noma i-DS-1.
