【摘要】 研究了叠前深度偏移在复杂构造模型成像中的应用。主要对一个复杂的地质模型所正演出的地震数据资料进行试验性处理,并对该试验性处理结果进行归纳分析,得出速度~深度模型的准确性决定于对偏移结果的质量以及根据地下构造选取偏移孔径的原则等定性认识和结论。通过这些认识和结论,对实际地震资料的处理有一定的指导意义。更多还原

【Abstract】 This paper studies the imaging ability of the pre-stack depth migration on complicated structures model. The work is mainly done by processing the data yielded from a complicated model, and analyzing the results. The results show that the quality of migration results depends on the accuracy of velocity-depth model and the migration apertures should be selected according to subsurface structures. These conclusions can be helpful for the processing of real seismic data.更多还原
