叠后地震多属性分析在煤层裂缝识别中的应用

针对山西新元矿煤层中的裂缝发育问题，以地震属性分析理论为指导，研究了相干、曲率、蚂蚁体等单一地震属性、多属性叠合、多属性神经网络运算裂缝概率等在裂缝识别中的应用效果，地震属性的走向确定了裂缝的方位信息，多属性分析圈定了裂缝发育区域。结合邻区已采掘区域揭露的断裂发育情况，表明以相干、曲率和蚂蚁体等叠后多属性对于裂缝的应用识别效果较好。地震多属性分析对于煤层裂缝的识别有着较好的应用价值，可推广至其他煤矿应用。

Application of post-stack seismic multi-attributes analysis in coalbed fracture identification

In order to study the fracture development in Xinyuan coal mine of Shanxi.Guided by the theory of seismic attribute analysis，studied the application result in fracture identification by the coherency，curvature，antbody，multiattribute composite，multi-attribute neural network computing fracture probability.Seismic attributes could determine the fracture azimuth information，and multi-attribute analysis framed the fracture development zone.Combined with the fracture development revealed in the excavated area of the adjacent area，it showed that the post-stack attributes of coherence，curvature and ant body were better for the application of fracture identification.Seismic multi-attribute analysis had a good application value for the identification of coal seam fractures and could be extended to other coal mine applications.
