The Application of the Numerical Simulation and Imaging of Seismic Scattered Wave in Exploration of Metal Mineral Deposits

The seismic data collected during the base metal exploration can be hampered by a variety of non-reflecting signals because of the heterogeneity of ore bodies and host rocks.It is difficult to produce a high-quality seismic profile when conventional seismic processing algorithms are applied to the data.According to the Huygens-Fresnel principle,every grid node can be considered as a vibrating source,and geological model can be discrete within the grids.Therefore we have stacked all kinds of waves,including scattered waves from these grids.It seems that the more scattered signals are used and the better the migrated section is.Two geological models are simulated and tested,one is the Tongling copper mine in the eastern China,and another is Gejiu tin mine in Yunnan Province of the south-western China.We have simulated the seismic scattering wave generated high-quality migrated seismic profiles,which match the geological models very well.It proves that imaging of the seismic scattered wave may be an appropriate tool to process the seismic data in base metal exploration.
