| Abstract: | The simulation response of the through-casing resistivity logging is studied by means of the improved transmission line equation method,and the factors of influencing the through-casing resistivity logging result are analyzed.Based on forward simulation,a set of test unit for detecting the weak signal of the through-casing resistivity logging is constructed for oilfield real casing.The high-precision data collection technology for the weak signal is studied and the nano-voltage level signal is successfully detected using the set of unit.This technique has reference significance to the development of through-casing resistivity logging instrument. |
