Asebenza kanjani amakholomu okubhoboza okungewona uzibuthe?

1. Umsebenzi we-non-magnetic drill collar

Njengoba wonke amathuluzi wokulinganisa 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 nguzibuthe futhi anensimu kazibuthe, ethinta amathuluzi okulinganisa kazibuthe futhi awakwazi ukuthola ulwazi olulungile lwesilinganiso se-wellbore trajectory. 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 yensimu kazibuthe ephazamisayo ngenhla nangaphansi kwekhola yokubhoboza ingenawo umthelela ethuluzini lokulinganisa, indawo engeyona enozibuthe iyadalelwa ithuluzi lokulinganisa kazibuthe, iqinisekisa ukuthi idatha elinganiswa ngethuluzi lokulinganisa kazibuthe iyiqiniso. ulwazi lwensimu ye-geomagnetic.

2. Izinto zekhola yokubhoboza okungezona uzibuthe

Izinto zekhola yokubhoboza 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 ehlinzeka ngamakholomu okubhoboza asezingeni futhi asongelwa ukusuka ku-3-1/8''OD kufika ku-14''OD ngokuvumelana ne-API, NS-1 noma i-DS-1.
