The perforating bullet detection experimental device is used to simulate the downhole high-temperature and high-pressure environment in which the perforating bullet performance is test. The perforating test tool is inside liquid-filled cylindrical wellbore cavity that is heated by heating wellbore wall with natural convection heat transfer. A mathematical model for unsteady heat-fluid-solid coupling heat transfer between the liquid in the wellbore cavity and the perforating test tool was established. The projection method is used to numerically solve the mathematical model, and the results of the dynamic heating evolution process of the perforation experimental device are calculated. The internal flow field and temperature field of the perforation experimental device with and without the perforating test tool in the wellbore are analyzed. Through the calculation and analysis results, it is found that the perforating test tool inside the simulated wellbore cavity has a greater influence on the flow field and temperature field.
