摘　　要：基于微测井技术和层析反演方法的各自优点,本文发展了基于微测井资料进行层析反演重建高分辨率近地表速度模型的方法,并进行了相应的高精度静校正量的计算,最后在我国南方某地区进行了实际应用.结果表明,该方法对于解决复杂地表条件下的近地表速度高分辨率建模以及高精度静校正问题具有较好的应用价值.Considering the respective advantages of the uphole survey and tomographic inversion, we have developed a combined method to reconstruct the high-resolution near-surface velocity model, and then carried out the high-precise computation of the static correction. We applied the new method to an exploration experiment in South China, and the result demonstrated that it is effective to resolve the problem of the near-surface velocity model and static correction under complex surface conditions.
