DELETION OF PSEUDO ECHO-SIGNALS FROM ACOUSTIC WAVES Russian patent published in 2017 - IPC E21B47/14

Abstract RU 2630005 C2

FIELD: physics.

SUBSTANCE: method involves deploying a well logging tool. Transmission of the first acoustic wave using a transmitting acoustic transducer of a logging tool. Reception of the second acoustic wave using a receiving acoustic transducer of a logging tool. The transmitting acoustic transducer of the logging tool is a receiving acoustic transducer of the logging tool, and wherein the deterministic wave is a pseudo-echo wave, removes a deterministic wave from the second acoustic wave to produce a reflected wave, and then extracts the measurement result from the reflected wave.

EFFECT: receiving a wave having only a true signal.
