【摘要】 在地震勘探中,地形的起伏、低降速带厚度和速度的变化造成反射波旅行时的畸变,严重影响了地震资料的处理质量。本文以层析静校正的基本理论和适用条件为基础,通过实际资料的应用,证明基于单炮初至时间的层析静校正方法能很好地解决复杂地表区由于地形和低降速带变化引起的长波长静校正问题。更多还原

【Abstract】 The processing quality of the seismic data can be seriously affected by the distortion of the reflection travel resulted from the changes in the geomorphic fluctuation, low weathering thickness and velocity. Based on the theory and applicable conditions of the tomographic static correction, it has been proved by the application of the real data that the tomographic static correction based on the first arrival time of single shot can solve the long wavelength static correction resulted from the changes in the geomorphic fluctuation, low weathering thickness and velocity in complex surface.更多还原
