【摘要】 在煤田地震勘探中,地形的起伏以及低速带厚度和速度的变化造成反射波旅行时的畸变,严重影响了地震资料的处理结果质量。因此,开展煤田地震资料静校正方法的研究,对于提高地震勘探成功率、降低勘探风险和节约勘探成本有着重要的意义。本文利用石油地震资料处理中的层析静校正技术,有效的解决了复杂地区煤田三维地震勘探静校正难的问题,提高了分辨率和信噪比。实例证明,该技术在煤田地质领域中的利用是有效的、也是可行的。更多还原

【Abstract】 In the earthquake exploration of the coal field,the ups and downs of the terrain and the changes of the depth and speed in the low-speed zone caused the distortion in the trip of the reflected waves,which has seriously affected the processing result of seismic data.Therefore,the research on the static correction method of coal seismic data is important to reduce the exploration risk and save exploration cost.In this paper,using chromatography static correction technology in the oil seismic data processing,it has effectively solved the difficult problem of static correction of the three-dimensional exploration in the coal field of complex areas and improved the resolution and the signal to noise ratio.更多还原
