摘　　要：水力压裂是油田提高勘探开发效率的核心技术之一,电磁监测是评估水力压裂效果的有效测量手段。该文升级改造了传统裂缝监测装置,搭建了基于电磁法的水力压裂裂缝在线监测实验教学平台,平台包含多种裂缝模型,且能合理设计各裂缝模型参数,以油田现场压裂裂缝监测问题为导向,灵活优化组合裂缝模型,使用COMSOL数值模拟及可视化方法,在实验室探索压裂裂缝参数与电磁监测信号间的规律,为反演有效裂缝参数提供理论依据。该实验项目具有前沿性、学术研究性和应用性选题特点,可以提升学生自主创新能力和实践探究能力。[Objective]Hydraulic fracturing technology is pivotal in the exploration and development of oil and gas fields.Among various methods,electromagnetic monitoring stands out for its nondestructive nature and high accuracy,proving to be an effective tool for evaluating hydraulic fracturing.This paper aims to advance the field by enhancing traditional fracture monitoring devices and creating an experimental teaching platform for online monitoring of hydraulic fractures using electromagnetic methods.[Methods]The proposed teaching platform integrates both numerical simulations and laboratory experiments.Initially,COMSOL software was used to conduct numerical simulations on the electromagnetic crack monitoring process,and then the laboratory experiment scheme was optimized based on the numerical simulation results.Subsequently,the teacher guided the students to conduct the laboratory fracture model monitoring experiment,and compared their results with those from the numerical simulations.This dual approach,combining virtual simulation experiments with hands-on laboratory work,allows for a deep dive into electromagnetic fracture monitoring technology.It opens avenues to explore the relationship between electromagnetic monitoring signals and fracture parameters more thoroughly.In the simulation phase,COMSOL was used to model the three-dimensional formation,wellbore,fracture,and electromagnetic detection tool.The mathematical model and boundary conditions of finite-element simulations were established based on Maxwell’s equations,and each model is meshed according to its interconnectivity.After establishing the simulation model,experiments were carried out to monitor the electromagnetic response signals of different fracture models.Numerical simulation exercises not only address students’uncertainties and complexities in the subject matter but also enhance their understanding and feedback on the experiment.The laboratory experiments,designed to mirror field fracturing processes,feature a visual fracture simulation syste
