Abstract
High temperature properties of 1-3 piezoelectric composite material sample were studied for borehole ultrasonic imaging logging. The pulse echo waveforms were measured from room temperature to 240°C. The curves of echo peak values, the central frequency and bandwidth extracted from the corresponding frequency spectrum, with changing temperature were obtained. The results showed that the material can work steadily and continuously under 210°C. This work will provide experimental data and basis for the development of high temperature ultrasonic transducers and borehole ultrasonic imaging logging tools.
