Abstract:DZ filter,a high pass filter,designed by S 3, Pirson, has concintric circular wavenumber responses.It can amplify both high wave- number content of signal and noise, OM, filter is a directional high pass filter.The two kinds of filter can not be used in alI conditions.Our N:filter, which is better used,was designed according to the magnetic field characteristics in SH area;its wavenumber response is The p5ssibility of oil magnetic detection is further discussed an the basis of the model exp0riment and the processed real magnetic data in B area, The comment on two kinds of current theory of oil magnetic exploration is made.Then,their demerits are pointed out,and the corresponding countermeasures given.
