In order to ensure that the acoustic logging tool while drilling works efficiently for a long time, it is necessary to manage the power management board efficiently. According to the power supply characteristics of the electronic system of acoustic logging while drilling, a power management and control circuit is designed. The low-power microprocessor PIC MCU controls the switch array of the power circuit according to the instructions of the measurement while drilling system, transmits the working parameters of the main control board through CAN-UART, and maps the well depth and downhole storage data by using the time information provided by the real-time clock circuit. For the purpose of intermittent timing operation of logging while drilling tool. The experimental results show that the power consumption of the power supply control circuit is 0.116 W, the on-off time of the switch is microsecond, and the output voltage is stable. The practical application satisfies the actual working requirement of acoustic logging while drilling tool.
