Abstract:
In an apparatus for multi-pole acoustic logging while drilling, a N-cycle sinusoidal wave signal is generated by utilizing a signal processor, and amplified into a high-voltage sinusoidal excitation signal by utilizing a power amplifier, and output to a transmitting transducer. The signal processor simultaneously generates an enable signal. The enable signal includes a transient discharge enable signal. The power amplifier is connected with a transient discharge circuit. After the signal processor generates N cycles of a sinusoidal wave, the transient discharge enable signal enables the transient discharge circuit to discharge to release an energy storage current of a power transformer so as to eliminate a high-voltage ringing effect and improve an excitation efficiency of the transducer.

Claim (Index 2):
The sinusoidal excitation method for multi-pole acoustic logging while drilling according to  claim 1 , wherein the transient discharge circuit comprises a gate drive chip and two high-power MOS transistors, wherein the two MOS transistors are connected in parallel, gates of the two parallelly connected MOS transistors are connected with the gate drive chip, sources of the two parallelly connected MOS transistors are connected with a first end of a resistor, and drains of the two parallelly connected MOS transistors are connected with two primary ports of the power amplifier, respectively, a second end of the resistor is grounded, and\n wherein, in the discharging step, the transient enable signal passes through the gate drive chip and controls the gates of the two parallelly connected MOS transistors to turn on the MOS transistors so that the energy stored in the power transformer is discharged via the resistor.
