槽波地震探测技术在窑街矿区油页岩层构造探测中的应用

Application of Trough Wave Seismic Exploration Technology in the Exploration of Oil Shale Structure in Yaojie Mining Area

通过槽波地震技术探查断层、陷落柱、薄煤区等地质构造已成为煤矿采掘生产领域较为成熟的勘探方法,但在非煤领域槽波地震的应用成果极少,利用透射槽波能量衰减成像技术在窑街矿区对断层构造进行探测,通过几何扩散的振幅衰减补偿方法提升窑街矿区油页岩层槽波资料信噪比,在油页岩层槽波发育一般的条件下依然取得较为清晰的探测成果。探采对比成果显示槽波地震在油页岩层构造勘探方面应用效果良好,可为油页岩层的采掘作业提供科学指导。

It has become a relatively mature exploration method in the field of coal mining and production to explore faults,subsided columns,thin coal areas and other geologic structures through trough wave seismic technology.However,the application achievement of trough wave seismic technology in non coal fields is rare.The transmission trough wave energy attenuation imaging technology is used to detect fault structures in Yaojie mining area,and the signal-to-noise ratio of oil shale trough wave data in Yaojie mining area is improved through the amplitude attenuation compensation method of geometric diffusion,under the condition of general development of oil shale trough waves,relatively clear exploration results are obtained.The results of exploration and mining comparison show that trough wave seismic has good application effect in oil shale layer structural exploration,which can provide scientific guidance for oil shale layers mining operations.
