High-temperature and high-pressure gas-solid-liquid multiphase mixed erosion corrosion coupling multifunctional experiment system

The invention discloses a high-temperature and high-pressure gas-solid-liquid multiphase mixed erosion corrosion coupling multifunctional experiment system. The system comprises a high-temperature and high-pressure gas supply module, a high-temperature liquid supply module, an adjustable sand supply module, a high-temperature and high-pressure medium mixing module, a detection and monitoring module, a corrosion gas supply module, an erosion corrosion test module, a recovery module and a control module. According to the invention, accurate simulation of oil and gas self-production in high-temperature and high-pressure working conditions during actual operation is realized, and experimental errors caused by inaccurate simulated working conditions can be eliminated; accurate simulation of gas-solid-liquid media in different working environments and adjustability of the gas-liquid-solid three-phase ratio are realized, so that the experimental test is closer to the real working environment, and the authenticity an
