三维地震资料在赵庄煤矿构造解释中的应用
|
摘要
基于赵庄煤矿为新开采的富含煤层气矿,矿区构造发育,煤层气的勘探开发前景不明确,为进一步查明本区构造发育特征,利用Landmark软件对赵庄煤矿的三维地震资料进行了精细解释。经地震剖面的构造精细解释,在剖面上共解释了4条断层,23个陷落柱并运用相干体技术直观地观察到该区域内断层和陷落柱的分布,对剖面解释进行了校正;运用地质构造控制理论煤层气富集规律分析结果表明,煤层气主要在向斜及背斜轴部、逆掩断层下降盘及埋深较大的区域富集,而陷落柱则沿逆掩断层、测区中部及西南角大量成片成带发育特征,且具有明显的分布不均特征,使得煤层的连续性较差,不利于煤层气的富集与保存。
Zhaozhuang Mine was a new developed coal mine with rich coal bed methane,a developed mine structure and an uncertain exploration development outlook of the coal bed methane.In order to verify the mine structure development features in the region,the Landmark software was applied to detail explain the 3D seismic information.With the detail explanation on the seismic section structures,there were 4 faults and 23 sink holes explained on the sections.The coherence cube technology was applied to directly observe the distributions of the faults and the sink holes in the region.The correction was made to the explanation of the sections.The geological structure control theory was applied to the analysis on the rich concentration of the coal bed methane and the results showed that coal bed methane would be mainly concentrated in the syncline and anticlinal axis part,the footwall of the reversed fault and the deep depth area.The sink holes were developed largely in pieces and zones along the reversed fault and the middle and the south-east corner of the region and had obvious uneven distribution features.Thus the sink holes had caused a poor continuity to the seams and would not be favorable to the rich concentration and storage of coal bed methane.
