Seismic Wave Numerical Value Forward Modeling Of The Scattered Field

In mining seismic exploration, the geologic structure and geologic body which faces is complex such as the abundant faults, the veins of rock, steep interfaces and so on. When different scale heterogeneity geological bodies are together, a very complicated seismic wave field can be formed by many types wave interference each other. in this kind of situation, The complicated seismic wave field cannot be described exactly in simplex wave (for example the reflection wave, the refraction wave etc.). It is demand to solve the complex geology problems in widely seismic scattered wave theory. Thus, to study seismic exploration technique on scattered wave is widely and practicably valuable in prospecting complicated geologic structure or heterogeneity bodies. Now the seismic exploration technique on scattered wave is being researched. Main research contents in the article:1. After the numerical simulation obtains the scattered wave field of different geologic model shot gather record in any depth and instantaneous wave front in any time, as well as in different stimulation the maximum amplitude intensity sectional view when the seismic wave propagate in underground. And analysis the seismic record, explain the wave field characteristic associate the geology model.2. Establish some geology models from easy to complex to calculate one by one, the goal is using the simple geology models to study the basic wave field' characteristic of the scattered wave, and using the complex model to study the complex wave field characteristic when the interference and diffraction existence. The key is analyzing the scattered wave and the geologic body corresponding relations along with the geological model changes, as well as the energy distribution (illumination intensity) of the seismic scattered wave in the underground and the known non-uniform ore body distribution corresponding relations, through the response of seismic wave scattering strong or weak to inference geology ore body. Thus examines the possibility of using the scattered wave seismic technology to seek the deep concealed Metallic ore.
