Abstract

One of the most important components in a downhole system for ultrasonic logging is the acoustic insulator which is used to prevent signals from propagating along the case of the tool between the transmitters and receivers. A poor-quality insulator would result in the appearance of a false first arrival which would interfere with the wide usage of such logs.
