In this paper

wavelet analysis is utilized to analyze and process the aero magnetic anomality of Sheng Li Oil Field. The wavelet property of aero magnetic of the oil field is studied

and the relationship between this property and the disrtibution of the underground oil is found. The result indicates that the distribution of underground oil location is the same as high frequency part derived from the aero magnetic anomaly signal.Furthermore

high frequency part is helpful to understand the controling factor of oil savings. Using this method

the authors predict by the other high frequency parts

and the results are acknowledged by the oil geoprahy experts working in local area.
