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 1):
A sinusoidal excitation method for multi-pole acoustic logging while drilling, comprising:\n generating a N-cycle sinusoidal wave signal and an enable signal in a signal processor, wherein the enable signal comprises a transient discharge enable signal and N is a positive integer; amplifying the sinusoidal wave signal into a high-voltage sinusoidal excitation signal in a power amplifier; and outputting the high-voltage sinusoidal excitation signal to a transmitting transducer; transmitting a transient discharge enable signal to a transient discharge circuit coupled with a power transformer; and discharging an energy stored in the power transformer through the discharge circuit so as to eliminate a high pressure ringing effect and improve an excitation efficiency of the transmitting transducer.
