用相干体属性开展断层识别

利用地震属性可以提高三维地震解释的精度和速度，并且节约成本，有利于矿井安全生产。在重点对相干体属性做出阐述和分析的基础上，以永城煤矿为研究区，首先正确合理选用相干体属性的最优参数，然后将相干体属性应用于实例获取数据体，再从属性数据体中提取出沿层切片，最后对地震数据进行相干体处理后得到了地震剖面。与不经相干处理的的地震原始剖面相比较，经相干处理的地震剖面更清晰地反映了地层和断层。相干体方法是有前途的地震剖面解释方法。

Fault Identification by the Coherency Attributes

The seismic attributes can be used to improve the accuracy and speed of the 3D earthquake interpretation, which can save the cost and are benefit to the mine safety production. On the basis of the analysis of the coherency attributes, the Yongcheng coal mine is selected as the research area. First, the optimal parameters of the coherent properties have been chosen correctly, and the coherency attributes have been applied to obtain the data body. And then, the strip is extracted from the property data body. Finally, the seismic profile has been obtained after the seismic data was processed by coherent body. The seismic profile processed by coherent body is clearer to indicate the formation and fault than that don't processed. The coherence method is a promising seismic profile interpretation method.
