摘要
文章设计搭建了高压流体注入诱发断层失稳模拟实验平台,实现了地应力、高压流体的组合加载,同步监测采集了典型岩样应变、流体压力及声发射等物理量的协同响应数据。该平台还可用于深部能源开发多物理场耦合特征研究。该实验直观展示了高压流体影响下断层的活动响应特征,在此基础上结合数值仿真实验,进一步加深了学生对实验现象和工程问题的理解,训练了学生多物理场监测仪器操作、科学问题分析及实践创新综合能力,实现了教学内容与工程实践、学术研究的紧密结合。
The article designs and builds a simulation experimental platform for high-pressure fluid injection induced fault instability,achieving combined loading of in-situ stress and high-pressure fluid,and synchronously monitoring and collecting collaborative response data of physical quantities such as strain,fluid pressure,and acoustic emission of typical rock samples.The platform can also be used to study the coupling characteristics of multi-physical fields in deep energy development.The experiment intuitively displayed the active response characteristics of faults under the influence of high-pressure fluid.On this basis,combined with numerical simulation experiments,it further deepened the students’understanding of experimental phenomena and engineering problems,trained students’comprehensive abilities of multi-physical fields monitoring instrument operation,scientific problem analysis and practical innovation,and realized the close combination of teaching content with engineering practice and academic research.
