摘要

A tool of nuclear magnetic resonance (NMR) to conduct measurements of Earth formation surrounding a Borehole and a methodof measurements (NMR) while making andL drill.The herramientatiene Mechanical force and Measurement sensitivity for measurements of nuclear magnetic resonance of an Earth formation.While Drilling The Hole Drilling.The tool has a imu00e1npermanente ma gnu00e9tico field whose direction is substantially perpendicular to the Axis of the hole DrillingA Steel collar of a Magnetic material surrounding the Antenna positioned outside the Magnet, a Necklace, and a Soft Magnetic material.Positioned in a certain relationship with the necklace and elimu00e1n that help shape the magnetic field of the tool.Due to the Magnetic Necklace, the tool can withstand the extreme conditions in the surroundings of the hole Drilling, while the hoyose is perforand or.The Invention also proposes a method to monitor the Movement of oftool MeasurementIn order to take account of that Movement when Processing signals from the hoyodeperforacion nuclear magnetic resonance.The meth Odo is used to identify periods when the nuclear magnetic resonance Measurements can be done without laprecision the Measurement is affected by the Movement ofThe tool or suorientacion Space.
