摘　　要：钻孔数据是地质中最常见且最简单的数据,利用钻孔数据直接建立三维地质模型已经成为国内外学者研究的焦点。在研究前人多种地质建模方法的基础上,结合工程实践,提出一套具有工程实用价值的优化地质建模方法。该方法以钻孔数据为基础数据,将钻孔地质剖面数据融入到地质建模中,修正了以往建模中尖灭点位置取值1/2区域的不合理情况,生成精确位置地层尖灭线;并且在建模的过程中加入了依据剖面图数据的模型调整。最后通过建模实例验证了该方法的准确性与有效性。The borehole data is the most common and simple geological data,establishing 3D geological model based on borehole data has become a focus for scholars both at home and abroad. On the basis of the former researchers,combined with practice,an optimized and practical approach for generating 3D geological models from borehole and cross section data is presented. The approach integrates the cross section data into the geological modeling,generates accurate pinch out line that correcting the position of pinch out which position unreasonable value1/2 region. And modifying result modeling by contrasting the cross section data in modeling flow. Finally the actual effect of the approach is shown in a case study.
