| Abstract: | A way of improving the poor stability and the easy breakdown of the voltage controlled components in the electronics circuit of the transmitting part of the 1609 acoustic log instrument is suggested in the paper. The work function of the instrument is improved by using silicon controlled rectifier to replace the original CMOS field effect transistor. The practice results show that the improvement makes the instrument stable and reliable in function and technique index of the tool, and so it meets the demand of logging better. |
