Oil and gas well drilling high-temperature and high-pressure dynamic friction simulation detection method

The invention discloses an oil and gas well drilling high-temperature and high-pressure dynamic friction simulation detection method, and relates to the technical field of oil and gas field development, and the method comprises the following steps: 1, processing a groove in one side of a standard cylindrical rock core to obtain a required rock core, fixing the rock core in a rock core clamping block through a locking piece, adding a to-be-detected drilling fluid system into the sealed kettle; 2, starting a heating part through a controller to heat the sealing kettle, and switching on a high-pressure gas source to enable the internal pressure of the sealing kettle to reach a pressure design value, so that a lower linkage rod rotates; 3, controlling the pressure of an external pressurizing rod to reach a pressurizing design value, and transmitting obtained data to a controller by a revolution and torsion sensor; and 4, the heating component is closed, and the pressurizing valve and the drilling fluid dischargin
