Abstract: A high-temperature and high-pressure microscopic visual flowing device and an experimental method are provided by the present disclosure, comprising a seepage simulation system, a micro-displacement and metering system connected to the seepage simulation system, and an image acquisition and analysis system; the seepage simulation system consists of a visual high-temperature and high-pressure kettle, a microscopic core model placed in the visual high-temperature and high-pressure kettle, and glass carriers arranged above and below the microscopic core model; the glass carriers are provided with sealing rubber sleeves, and the visual high-temperature and high-pressure kettle is provided with an annular heating jacket; an outlet of the microscopic core model is provided with a microflow channel which is connected to the micro-displacement and metering system through a pipe, effectively reducing the metering error caused by the dead volume of the pipe.
