【摘要】 目前的地震勘探工作还处在构造勘探阶段,地震勘探取得的地质信息中仅解释了其中的快纵波的反射波场特征,而慢纵波的能量信息没能利用。基于双相介质理论的地震资料处理与反演技术,采用数字滤波的方法提取地震波能量信息,找到了地震波能量信息与煤层瓦斯之间的内在联系,取得能够反映瓦斯富集区的能量信息结果图,经实际应用对比效果明显。利用现有的三维地震勘探资料作进一步的反演处理为煤矿提供瓦斯富集区研究具有应用价值。更多还原

【Abstract】 The present seismic survey work was at the tectonic survey stage.The geological information obtained from the seismic survey only could explain the features of the rapid longitudinal reflection wave field,but the slow longitudinal wave energy information could not be used.Based on the seismic information treatment and reversed evolution technology of the double phase medium theory,the digital filtration wave method was applied to collect the seismic wave energy information.The intrinsic relations between the seismic wave energy information and the seam gas were obtained.The energy information result map reflecting gas rich concentrated zone was obtained.The results of the practical application comparison were obvious.The application of the present 3D seismic survey information to the further reversed evolution could provide the applied value to the research on the gas rich concentrated zone of the mine.更多还原
