FIELD: soil or rock drilling.
SUBSTANCE: invention relates to well drilling and, more particularly, to a nuclear magnetic resonance tool. Downhole tool comprises a tool body, a magnetic field source connected to the tool body, an antenna, connected to the tool body and a radial protrusion from the tool body near the antenna and inclined relative to a longitudinal axis of the tool body.
EFFECT: technical result is higher effectiveness of measurements.
