摘要
折射层析反演静校正能够较好地解决复杂近地表引起的静校正量问题。该技术最新的算法利用非显式的射线追踪方法求解近地表模型,有更强的适应性和灵活性,减少了复杂地表和地质条件下速度／深度模型的不确定性,提高了模型的精度。在伊朗卡山地区三维地震资料处理过程中,利用该项技术很好地解决了近地表引起的静校正问题。
The paper introduces a new method of refraction tomo-graphic inversion static correction, which can properly calculate the statics resulted from complex near-surface conditions. New algorithm utilizes an implicit ray tracing to determine the near-surface model, thus the new method is more powerful and flexible, leading to reduction of uncertainty in velocity/depth model in complex subsurface and near surface geological environment. Satisfactory results have been reached during the processing of 3-D seismic data from Kashan Block of Iran by using the proposed method.
