The wavelet property of the geomagnetic anomaly signal

Abstract In this study, wavelet analysis is utilized to analyze the geomagnetic signals for oil-gas exploration, in order to show the relation between the wavelet property of the geomagnetic signals and the underground treasure. At first, the global geomagnetic anomaly signal in the oil exploration is given. Then, with the wavelet theory the geomagnetic signals of an oil-gas field is analyzed. The preliminary wavelet analysis shows that the underground oil-gas location can be determined with the help of its regional high frequency signal distributions.
