数字图像重建技术在岩石渗流类课程教学中的应用

提升高校岩石渗流类课程的教学效果对保障国家建设和能源开采的人才供应具有重要意义。针对传统教学中存在的不足,本文提出了一种结合岩石微观数字图像及其重建模型的新型课堂教学方法。以某砂岩微CT图像为例,本文详细介绍了在岩石多孔介质特性、单相-两相流体输运特征教学中的课程案例,详细论述了该方法在各关键知识点讲解中的应用。分析表明,本文提出的授课方法有助于改善空洞、乏味的授课方式,从而提升了该类课程的教学效果。

It is of significant importance to ensure the demands of technical talents for national construction and energy extraction of China by promoting the teaching efficiency of high education courses related to seepage mechanism in rock and soil. Regarding to the existing shortage of traditional teaching method, this paper presents an improved teaching case using the digital images and reconstructed models of rock. The detailed teaching cases including the nonhomogeneous porous media characteristics of rock and single-/two-phase flow are designed using the sandstone micro-CT images. Then the key knowledge points are analysed. It is indicated that the proposed teaching methods have been proved to enrich the teaching mode and improve the teaching efficiency.
