三维相干技术在白家海地区构造解释中的应用

Application of 3D coherence cube technique in the baijiahai region structural interpretation

随着地震技术的深入发展,地震资料解释相继也得到了进一步的发展,由相干技术公司（CTC）和Amoco公司发明代表性相干体技术,主要是利用三维地震数据体中地震信号相干值的变化来描述地层、岩性等的横向非均匀性,从而研究断层、微断裂的空间展布、地质构造的异常以及岩性的空间分布特征,为地震资料解释奠定了更好的方法基础。在前人资料的基础之上,本文主要研究了三维相干体技术在白家海地区断层识别中的应用与实现,并通过相关函数来突出地震数据中出现断层时的数据的不均匀性,接着对相干数据体作时间切片,进而将断层更加清晰的显示。

With the further development of seismic technology, have also obtained the further development of seismic data, the coherence technology companies（CTC） and Amoco company representative coherence technology invention, main is to use 3 d seismic data volume to describe the seismic signal coherence value changes in strata, lithology and lateral heterogeneity of the spatial distribution of the faults, micro fracture, abnormal geological structure and spatial distribution characteristics of lithology, laid a better method for seismic data interpretation.On the basis of previous data, this paper mainly studies the 3 d coherence technology in White House sea area, the application of fault recognition and implementation, and highlighting seismic data by correlation function in inhomogeneity of data when fault, then the time slice of coherent data volume, and then the fault is more clear.
