On Numerical Simulating and Measurement for Weak Signal of Through Casing Resistivity Logging

Estimated with numerical simulation is the magnitude of signal output from through casing formation resistivity logging(TCFRL),formation resistivity logging curve of TCFRL is simulated with transmission line method,then the characteristic of TCFRL response is analyzed,as well as an elemental measurement electronic is experimented.Thus,the conception that weak signal detection is the key of TCFRL technology is realized more practically.
