Method for constructing diffraction images of fractured-cavernous zones on the basis of multidimensional spectral filtration and new possibilities for studying the properties of geological media on the basis of multidimensional seismic data analysis of a common image point

Abstract

The article describes the results of applying the original seismic data processing methods: Common Scattering Point Dip (CSPD) and Vector Pair Reverse Time Migration (VPRTM). Specific examples show that the CSPD method allows to effectively solve a wide range of tasks at various stages of geological exploration: search for fractured-cavernous zones, isolation of the cured faults, contouring of granite intrusion, identification of hazardous drilling zones and geonavigation of horizontal drilling. The VPRTM method is effective not only for detecting weak diffractors but also promising for simultaneous accurate analysis in various procedures.
