Virtual Simulation Teaching Design for Rock Mechanics Experiments in Petroleum Engineering

岩石力学实验是石油工程、海洋油气工程专业的基础实验课程,但物模实验存在“设备贵成本高”、“操作难周期长”、“演示直观性不足”等问题。为此,本文拟配合“石油工程岩石力学”课程中“岩石强度理论”教学内容的授课需要,借助现代虚拟仿真技术,基于石油工程岩石力学理论,理清岩石力学三轴实验设备原理,分析岩石力学实验操作步骤,辅之以井壁稳定科研知识,集成于虚拟交互系统中,达到理论、实践、创新、节约、安全有序结合的目标。有利于岩石力学实验的可重复性,实现岩石力学实验的可观察性,提高学生分析问题和解决问题的能力。

Rock mechanics experiments are a basic experimental course for petroleum engineering and offshore oil and gas engineering majors, but there are some problems in physical model experiments, such as “expensive equipment and high cost”, “difficult operation and long cycle”, and “insufficient intuitiveness of demonstration”. Therefore, this article intends to meet the teaching needs of “Rock Strength Theory” in the “Petroleum Engineering Rock Mechanics” course. With the help of modern virtual simulation technology and based on the theory of petroleum engineering rock mechanics, the principle of triaxial experimental equipment for rock mechanics is clarified, and the operational steps of rock mechanics are analyzed. With the assistance of wellbore stability research knowledge, it is integrated into a virtual interactive system to achieve the goal of orderly integration of theory, practice, innovation, economy, and safety. It is beneficial for the repeatability of rock mechanics experiments, achieving observability of rock mechanics experiments, and improving students’ ability to analyze and solve problems.
