摘要
三维地震勘探成果数据体包含丰富的地质信息,任意物性反射层均可作为钻孔地层划分的依据。物性反射层等深线数据文件与GMS中钻孔数据文件通过点的空间坐标相互关联,可高效地构建GMS中地层实体建模所需的虚拟钻孔。实践表明,该方法具有很高的地层建模精度,能成倍提高工作效率,同时也为三维地震勘探成果中其它物性特征的获取利用提供了一个可借鉴方式。
3D seismic exploration data contain abundant geo-information,any physical reflected surface is one of the most important data,which can provide the evidence to divide strata in borehole.Data files of physical reflected surface depth contour and data files of borehole in GMS are interrelated by the point positions.The high performance method of constructing virtual boreholes for models of stratigraphy under the platform of GMS was developed by this means.It was found that the precision of stratigraphy modeling can be increased,and the work efficiency can be improved,at the same time the practicable way for using other physical data in 3D seismic exploration data was put forward by this method.
