The high-temperature, high-pressure core damage experimental device is an advanced experimental device designed specifically for the petroleum exploration and development field. It aims to simulate reservoir pressure and temperature conditions, study reservoir damage mechanisms, and provide a scientific basis for improving oil and gas recovery and protecting oil and gas reservoirs. The device has a liquid permeability determination function. By measuring the pressure difference at the core inlet and outlet and the liquid flow rate, the liquid permeability of the core is calculated, providing accurate data for reservoir permeability research. The device can be used to study the degree of damage to the formation caused by foreign substances during drilling, completion, water injection, production enhancement measures, and workover operations; to screen drilling fluid systems; to evaluate the damage to the reservoir caused by different drilling fluid systems; and to select suitable drilling fluids. The device is equipped with an advanced data acquisition and control system. With a simple interface and easy operation, it can collect and transmit pressure, temperature, flow rate, and other data in real time, facilitating experimental operation and data management.
