三维地震资料解释煤层中岩浆侵入体在晓南煤矿西二采区的应用

Application of 3D Seismic Data Interpretation of Coal Seam Igneous Intrusion in West No.2 Working Area, Xiaonan Coalmine

晓南煤矿含煤地层属侏罗系陆相沉积。因地质构造运动,采区内有大面积岩浆岩侵入,不同程度地改变了煤岩物理性质。利用三维地震资料解释技术,如垂直时间剖面水平切片及面块切片,根据其不同特征结合钻探资料,可以比较直观地判断岩浆侵入体的大小及范围。

Coal measures in Xiaonan coalmine belong to Jurassic terrestrial deposit. Because of tectonic movement, there is large igneous intrusion in the working area and changed physical properties of coal and rock in different extent. By the use of 3D seismic data interpretation techniques, such as vertical time section time slice and surface slice. According to their different characteristics and drilling data, may estimate size and scope of igneous intrusion more intuitively.
