|
摘要
基于双相介质理论,对地震资料采用最大能量扫描法提取出地震波能量信息,得到能够反映流体信息的能量分布图。根据钻孔瓦斯检测值和井下煤样瓦斯检测值与三维地震资料预测的能量值的对比分析找出其相应的关系,定量分析瓦斯富集区的地震波能量值与瓦斯值的关系,为矿方进行地面瓦斯预抽布置钻孔和井下预防瓦斯突出提供地质依据。
Based on the theory of double-phase medium,the maximum energy scan method is used to extract the wave energy information from seismic data,the energy distribution which can reflect the flow of information is obtained. According to the comparative of drilling hole gas detection value and coal mine gas detection with the energy value obtained by prediction of 3D seismic data to find out the corresponding relationship,analysis of the relationship between gas value and seismic wave energy of gas enrichment area,provides the geological basis for the mine to conduct the ground gas drainage and drill layout and the mine gas outburst prevention.
