ADAPTIVE OPTIMIZATION OF OUTPUT POWER, WAVEFORM AND MODE FOR IMPROVING ACOUSTIC TOOLS PERFORMANCE

摘要

A method and system for enhancing the signal quality of received signals generated by acoustic tools by factoring in feedbacks from the rig operations in an adaptive optimization process. The system may include a transmitter driver circuit and transmitters which can implement signal transmission at selected power, mode and waveforms. The selected power, mode and transmit waveforms may further be generated in the system by making optimal calculations based on realtime information from the downhole data regarding the formation and borehole characteristics.
