Abstract
The skin effect of metal casing is analyzed, a ultra-low frequency signal source is put forward in cased hole resistivity logging technology. In this technology, the direct detection signal order is microvolt, the useful signal order is nanovolt. Based on the characteristics of this technology, the phase sensitive technique is put forward in this paper for improving the accuracy of data acquisition. The logging signal frequency effect on detection is analyzed, and the specific solution is given. The results have been applied in design of signal source and weak signal acquisition system.
