地震勘探资料解释研究

Study on Seismic Prospecting Data Interpretation

在二维和三维地震勘探中,不论时间剖面还是数据体,解释资料时都遵循着对比解释准则。解释成果与实际揭露的资料不符,主要是没有把握住反射波的特征点。当地下界面发生变化时,在时间剖面上一般都伴随着一些特殊波出现或者反射波发生畸变等现象,都是要值得注意和分析的要点。以大城勘查区二维地震勘探时间剖面解释出的反屋脊断层为例,利用好各种特殊波,为增强解释成果的可靠性提供了更完善的技术手段。

In the 2 d and 3 d seismic exploration, regardless of time section or data volume, all followed the comparative interpretation criterion when interpreting data. When interpretation result was not in conformity with the practical data,mainly because did not get the characteristics of reflected wave. Under the local interface changes, was the time section was generally accompanied by some special wave or reflection wave phenomenon such as distortion, which was worthy of attention and analysis, 2 d seismic time profile of the opposite roof fault in Dacheng exploration area was taken as an example, making good use of all kinds of special wave provided a more perfect technology for enhancing the reliability of interpretation results.
