| It has been 50 years that our country spent on the seismic prospecting of southern marinefacies carbonatite exploratory areas, which indicates the southern marine layer is a largepotential oil area. There are many characteristics for the southern marine area, for instance,the surface elevation of these areas changes sharply, the high transmition speed of nearsurface, the lithological characters complication of the surface, which brings difficulties foracquisition, processing and interpretation of oil and gas exploration. The problems arereflected on three main aspects: firstly, topographic relief is a serious hinder for staticscorrection; secondly, there are different kinds of interference waves exist on the high velocitylayer; thirdly, the complicated near surface velocity structure and the topography affect thesubsurface reflected wave obviously and even seriously. The paper, based on the researches ofsouthern marine areas and the methods of datum static correction of the wave equation, isinstructive to seismic data processing and imaging under the complicated geologicalconditions.On the base of analysis of the southern marine area features, the seismic and geologicalproblems, this paper analyses various kinds of removal surface-wave methods and theproblems.We can use the multi-wavelet seismic trace decomposition method for surface-waveremoval.The base of the method is that a seismic data trace can be decomposed into a set of surfacesignal component of different dominant frequencies and amplitudes.By properly selecting thesignal component of surface-wavelets can be excluded and the new reconstructed seismictrace do not include the surface-wave.The paper completes the program of the multi-wavelet decomposition,In the southernmarine facies,using the method for surface-wave elimination, meanwhile the reflected-wave iseffectively kept. Therefore it can be used to process the real seismic data and provide a goodoriginal data for the seismic imagining.
