摘要

针对柳塔矿区黄沙覆盖、地形起伏大、煤层埋深浅、煤层多、小断层发育等不利于地震勘探的特点,采用小线距、小偏移距技术解决了地形起伏大、煤层埋深浅的问题;采用宽方位角观测系统、宽频带接收、叠前三维地表一致性补偿、三维地表一致性反褶积等手段最大限度的提高了地震资料的分辨率,提高了成像精度;解释过程中采用波阻抗反演与地震综合属性分析技术确定了煤层的范围,利用相干体分析技术搞清了断层特别是小断层的发育情况,取得了良好的地质效果与经济效益。
In view of the Liuta mining area yellow sand cover,the hypsography are big,the coal bed buries the depth,the coal bed to be many,the small fault growth and so on does not favor the seismic survey the characteristic,used the small line-spacing,slightly to off-set the technology to solve the hypsography to be big,the coal bed buried the depth the question.By the width azimuth observation system,the wideband receiving,folds 3D surface uniform oscillation amplitude to compensate,the 3D surface uniformity deconvolution and so on,the methods enhanced the material resolution maximum limit,increased the imagery precision;In the process of Explanation,with the wave impedance inversion and the seismic survey analysis technology has clarified the small faults,specially the growth situation of the small faults,which has obtained the good geological effect and the economic efficiency.
