【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。
[Abstract]:Borehole data is the most common and simplest data in geology. It has become the focus of scholars at home and abroad to establish 3D geological model directly from borehole data. Based on the research of many geological modeling methods and engineering practice, a set of optimal geological modeling methods with practical engineering value is put forward. This method takes drilling data as the basic data and integrates the borehole geological profile data into the geological modeling. It corrects the unreasonable situation of 1 / 2 region where the point out point position is taken in the previous modeling, and generates the accurate position stratum tip extinguishing line. And the model adjustment based on the profile data is added in the modeling process. Finally, the accuracy and validity of the method are verified by a modeling example.
