“新工科”背景下毛管力虚拟仿真对分课堂教学实践

PAD classroom teaching practice of capillary pressure virtual simulation under background of new engineering

毛管力曲线是低渗致密油藏开发设计的重要基础资料,其测试方法和应用是石油工程专业课程教学中的重要环节。基于"新工科"理念,建设了交互式毛管力虚拟仿真测试教学系统,设计了基于该系统的虚实结合毛管力测试与应用对分课堂教学法。将常规压汞法毛管力实验教学拓展到适用于非常规油气开发的高压及恒速压汞毛管力曲线测试和应用教学,消除了实验教学中汞的毒害性影响,提升了毛管力测试课堂教学素材的广度及技术前沿性。同时,结合对分课堂教学法,大大提升了教学效果。

Capillary force curve is an important basic data for the development and design of low permeability tight reservoir,and its test method and application are important links in the teaching of petroleum engineering professional course.Based on the concept of"New engineering^^,an interactive virtual simulation teaching system of capillary force is constructed,and a PAD(presentation,assimilation and discussion)classroom teaching method based on the system of virtual and real capillary force testing and application is designed.The conventional mercury injection capillary force experiment teaching is extended to the high pressure and constant speed mercury injection capillary force curve test and application teaching applicable to unconventional oil and gas development,which eliminates the toxic effect of mercury in the experiment teaching and improves the breadth and technical frontier of the classroom teaching materials for capillary force test.At the same time,combined with the PAD method,the teaching effect is greatly improved.
