摘要
常规地震勘探方法都是基于单相介质中的弹性波动方程,忽略了流体对地震波传播规律的影响。本文基于双相介质理论,探讨了游离态的瓦斯在煤田地震资料上的地震波场特征,旨在有效地判断瓦斯的富集区域,防治煤与瓦斯突出给矿井生产带来的灾难。
The seismic exploitation plays an important role on looking for possible hydrocarbon structure, Coal geology structure. And the research is based on elastic wave equation of single-phase media, ignoring the liquid influencing on seismic wave transmit. article discusses seismic wave field feature of free form gas on coal seismic data based on double-phase media theory, aimed at effectively judging abundance zone of gas, and controlling mischance arose by coal and gas outburst.
