地震属性方法在煤矿采空区解释上的应用
|
摘要
以河东煤田乡宁矿区的地震勘探为例,在分析采空区形成的地质条件、地球物理特征及其地震属性响应的基础上,从20多种属性中优选出对采空区较为敏感的平均振幅能量值、振幅正负极值比、最大反射率、瞬时频率、瞬时相位等属性,为采空区解释取得了理想的效果。。
With the Xiangning ore district of the Hedong coalfield as an example and on the basis of an analysis of the geological conditions,geophysical characteristics and the seismic attributes responses,the author selected several seismic attributes that are relatively sensitive to the golf of coalfield from more than twenty attributes,such as average amplitude energy value,ratio of positive to negative peak amplitudes,maximum reflectance,instantaneous frequency and instantaneous phase,thus obtaining ideal result in the interpretation of golf in coalfield.
