BOREHOLE COMPENSATED RESISTIVITY LOGGING TOOL HAVING AN ASYMMETRIC ANTENNA SPACING
摘要:
A compensated resistivity logging while drilling tool having axially asymmetrically spaced transmitters is configured to provide compensated resistivity measurements. In one exemplary embodiment, the tool includes first and second compensating transmitters, preferably deployed axially symmetrically between first and second spaced receivers. The tool further includes a plurality of transmitters deployed axially asymmetrically with respect to the receivers, e.g., on one axial side of the receivers. The compensating transmitters are configured to acquire a borehole compensation that may be subtracted from conventional phase and attenuation measurements.
