The invention relates to the technical field of scale inhibitor injection, in particular to a hydrogenation scale inhibitor high-temperature cavitation prevention injection structure. Comprising an agent storage shell, a fixing cover is installed on an oil slurry pipe, a cavity is formed in the fixing cover, an agent injection shell is fixedly connected to the agent storage shell, an electric control telescopic rod is fixedly connected to the agent storage shell, an agent injection plate is fixedly connected to the telescopic end of the electric control telescopic rod, and a one-way plate is fixedly connected to the agent injection plate through a connecting rod; the fixing cover is fixedly connected with an air release valve, a heat conduction rod is connected into the fixing cover in a sliding mode, and the fixing cover is fixedly connected with an injection agent pipeline. The scale inhibitor liquid is heated through the heat conduction rod, and then the heated scale inhibitor liquid is injected into the o
