摘要: 现有的钻孔自动建模算法要求对原始钻孔数据进行解译。为解决现有钻孔解译方法效率低、易出错等不足,提出了基于层位标定的钻孔数据快速解译方法。该方法以层面下沉的方式生成和标定模型中的各个地质界面,并自动将层面编号记录到钻孔分层点上。解译过程中,层面的下沉和确定都由解译者灵活控制。人机交互的方式使得专家经验可以很容易地融入解译过程中。基于该方法开发的解译软件,提供了三维场景中直观的交互式解译工具,辅助解译者快速、准确地完成钻孔解译。在实际钻孔解译工作中的成功应用,证明该方法能够很好地处理工程实践中的复杂问题。Abstract: Raw borehole data have to be deciphered to carry out auto-modeling from boreholes.To overcome the disadvantages in the existing borehole deciphering methods,such as inefficiency and fallibility,a quick borehole deciphering method based on stratum tagging is proposed.It generates and tags each geological surface of the resulted model in manner of sinking the bedding surface,and automatically assigns the number of the surface to the dividing points on each borehole.During the deciphering process,the sinking and confirmation of the bedding surface can be controlled easily by decipherers.The interaction between the human and computers makes it easy to bring expertise into the deciphering process.The deciphering software developed with the method supplies an intuitionistic interactive tool in the three-dimensional scene,which helps decipherers to carry out deciphering quickly and accurately.Successful application to real borehole deciphering has demonstrated its ability to solve complicated problems in engineering practice.
