Abstract
The invention relates to a slim sonic logging tool with multiple modules for borehole resonance mode and pitch-catch measurement, comprising a cylindrical housing, a monopole transmitter, a pair of cross-dipole transmitters and a ring of receivers disposed between the monopole transmitter and the pair of cross-dipole transmitters within the cylindrical housing, the ring of receivers, being axially around a circumference of the first cylindrical housing.
Claims21
A borehole acoustic logging tool, comprising:
- a resonance mode measurement module including:
- a first cylindrical housing including a longitudinal axis;
- a first monopole transmitter disposed within the first cylindrical housing;
- a pair of cross-dipole transmitters disposed within the first cylindrical housing;
- and
- at least one ring of receivers disposed between the first monopole transmitter and at least one cross-dipole transmitter of the pair of cross-dipole transmitters within the first cylindrical housing, the ring of receivers being azimuthally arranged around a circumference of the first cylindrical housing, and the receivers, the first monopole transmitter and the pair of cross-dipole transmitters are placed to ensure a quasi-vertical resolution with respect to the logging tool.
