High temperature and high pressure shale imbibition experimental system design

Combined with the mechanism of shale oil reservoir imbibition to enhance oil recovery, a set of high-temperature and high-pressure shale imbibition experimental system is designed. According to its built-in imbibition displacement system, it can simulate the imbibition effect of shale oil reservoir during shut-in, simulate the pressure and temperature conditions of the reservoir through the temperature and pressure coordination control system, and accurately measure the core weight or imbibition fluid volume in combination with the data acquisition system. This system can carry out research on factors affecting shale imbibition and evaluate the imbibition recovery effect of shale oil reservoir. It has applicability and accuracy, and is conducive to stimulating students' innovative spirit, cultivating interdisciplinary thinking, and strengthening the ability to solve practical engineering problems in unity and cooperation.
