煤矿地震数据三维可视化研究

The 3D visualization of coal seismic data

摘要: 根据煤矿地震数据二维解释中存在的问题,以及三维可视化在三维地震解释中的优势,将三维可视化技术应用到煤矿地震数据解释中。结合煤矿地震数据特点,研究了OpenGL和VC++6.0联合编程,利用适合地震数据三维显示算法,研制了基于Windows的煤矿地震数据三维可视化系统Sgy3D。Sgy3D系统基本功能包括数据体、Inline剖面、Crossline剖面、层位、等值线、任意测线等要素的三维立体显示;实现了对数据体的动态放大、缩小、平移等交互操作。将Sgy3D应用于实际地震资料解释,取得了良好的地质效果。

Abstract: Depending on the problem of two-dimensional interpretation in coal mine seismic data and advantage of 3D visualization in interpretation,3D visualization was applied to interpretation.With consideration the features of 3D coal seismic data,programming combine with,OpenGL and VC++ 6.0 were researched.Based on coal seismic data characteristics,the system of Sgy3D based on windows was developed.Function in Sgy3D contain: display volume,profile of inline,cross line,time slice,contour,arbitrary line.Much operation can be realized,such as zoom in any size,move.Applications with Sgy3D generate good effects for seismic exploration and real-time seismic analysis.
