Abstract: Taking the high-pressure property determination test of formation oil as an example, digital teaching resources are developed and an online virtual classroom is constructed. The online and offline blended teaching is used to break through the limits of teaching time and space, expand the experimental contents to cover the processes of oil sampling, preparing, transferring, testing and analyzing. A part of the research on carbon dioxide oil flooding and storage mechanism is integrated to the experiment to closely follow the frontier research hotspots in the field of petroleum engineering, so as to improve the original confirmatory experiment to an exploratory experiment. A student-oriented flipped experiment teaching mode is constructed, in which a multi-dimentional assessment method of “teacher + students”, “process + results” and “normal + difficult” implemented in the stages of pre-class, at-class and after-class is used to evaluate the experimental score. These measures effectively solve some problems existing in the traditional experimental teaching, improve the “high-level, innovation and challenge” of the confirmatory experiment, and increase the “gold” content of the petroleum engineering experiment course.
