摘要:
伏龙泉断陷区域构造比较复杂,断裂极为发育,由于受到地震分辨率的限制,很难对较小的断层进行准确的解释。针对这些问题,尝试使用分频相干的方法来解决。将地震数据分解为一系列单频体,对每一个单频体进行相干计算,挑选对断层刻画较为清楚的单频体进行断层的剖面解释; 然后提取目的层段的多个单频平面相干属性,并使用RGB融合技术将不同单频相干属性融合起来进行断层平面解释。结果表明,分频相干技术在复杂构造的断裂解释上有着良好的应用效果。
Abstract:
Fulongquan Faulted Sag has complicated structures,in which faults were well developed.Due to the limits of seismic resolution,it is difficult to precisely describe smaller faults.To resolve this problem,it was proposed the discrete frequency coherency technology.Firstly,the seismic data were decomposed into a series of mono-frequency cubes,and the coherency of each mono-frequency cube was calculated.And then the mono-frequency cubes clearly describing faults were selected to interpret the fault section.Secondly,several plane coherent properties of mono-frequency were extracted from target intervals.And then using RGB fusion technology,various coherent properties of mono-frequency were combined to interpret the fault plane.Results showed that the discrete frequency coherency technology has a good application effect on interpreting complex structure faults.
