Method to Depress Trailing Excitation Signal in Acoustic Well Logging

Acoustic well logging adopts electrical excitation sources to produce instantaneous high-voltage pulse signals of thousands of voltages. Meanwhile, long-time trailing parts are always generated in these electronic signals after the desired excitation parts. These trailing signals influence the process of logging. In this paper, we study a new circuit to depress these trailing signals. Firstly, we introduce the hardware design and software workflow of the circuit. Thereafter, electronic experiments are performed to certify the depressing effect. Results illustrate the circuit is easy to realize and is suitable for high voltages of 4000 Volts. It can work as a separate circuit, or be integrated into any transducer excitation circuit.
