【Abstract】 The basic principle of the seismic tomography and electromagnetic field tomography, the two major type of tomogrphic techniques for geophysical prospecting,and conventional reconstruction algorithems are briefly described. The basic principle and properties of maximum entropy reconstruction algorithem and the curved ray tracing algorithem are then introduced based on our research results. Two field examples are used to demonstrate the effectiveness of these algorithems as well as the resolution capability of the tomography. Finally, the possibility and difficulty for applying tomographic technique to petroleum exploration and production are explored.更多还原
