摘要

在近地表速度结构变化较快的地区,能否做好静校正直接决定了地震勘探效果。而在复杂地区三维资料处理中,很难用一种方法彻底解决整个区块的静校正问题。为此,以非线性层析反演静校正方法为基础,在平面上对速度模型进行相带划分,以及用小折射和微测井资料作为初始模型,进行约束层析反演,可大大提高模型的垂向反演精度和空间合理性。对不同静校正方法具有成像优势的高频静校正量,采用拼接方法,在边界用函数插值方法进行处理,可实现多种方法在一个三维区块成像优势的结合。以上复杂地区三维静校正综合技术,在实际三维资料处理中见到了很好的应用效果。

Abstract

In the area near surface with swift change of velocity structure, static correction is significant for seismic exploration. A single method is hard to make a right static correction in the three-dimensional seismic integration. So, based on nonlinear tomographic inversion, phase belt plot of velocity model in plane section, and short refraction and minilog data as initial model, we can make the tomographic inversion improve the vertical inversion precision and spacial reasonability. For the high frequency static correction values that has imaging advantage, we piece together, then use function interpolation at boundary. Thus, the imaging advantage of different methods in a 3D block can be used. The 3D static correction technology has been used in some complex areas, and the good results has been gotten.
