A New Downhole EWR Measurement and Communication System Based On DPSD
2021
A new downhole electromagnetic wave resistivity (EWR) measurement and communication system based on digital phase sensitive detection (DPSD) is presented in this paper. The purpose is to solve the problem of EWR raw data measurement and wireless transmission of measurement data in the process of downhole petroleum exploration. The implementation of this system depends on the transmission of electromagnetic waves. The System uses digital system control (DSC) as the main control of the system, and combines field programmable gate array (FPGA) to realize the function of electromagnetic signal transmission, acquisition and detection.
