摘要

鄂尔多斯盆地南部为黄土塬区,地表条件复杂,黄土巨厚,干燥疏松,静校正问题严重,资料信噪比低,给地震资料处理带来很大难度。应用了非线性层析反演方法有效地解决了黄土塬区静校正问题,将加密速度分析与地表一致性剩余静校正多次迭代相结合,提高了剖面的质量。实际资料的处理表明,在黄土塬区该方法的应用能有效提高成像质量。
In the south of Ordos Basin,surface condition in loess tableland area was complicated,loess was thick,dry and loose,there existed serious problem of correction,data signal to noise ratio was low,it resulted in great difficulty for seismic data processing.A nonlinear tomographic inversion method of TOMODEL system was used to effectively solve the problem of static correction in loess tableland area.The encryption speed analysis was combined with surface consistent residual static correction technology,thus the quality of the profile was improved.The actual data processing shows that in the loess tableland area the method can be used to effectively improve the image quality.
