The invention discloses a deep oil and gas reservoir solid phase generation and blockage damage prediction method, and belongs to the technical field of oil and gas reservoir development. Establishing a mathematical model of a one-dimensional reaction flow in the porous medium according to a mass balance equation of the two reactants, a kinetic equation of a reaction rate and a Darcy law, and carrying out nondimensionalization on the mathematical model; solving the dimensionless model to obtain a pressure drop model; according to the Darcy law and the pressure drop model, the damage condition of the hydrocarbon reservoir is judged. According to the method, the influence of solid-phase particles generated during fluid convergence in the reservoir on the damage degree of the reservoir is considered, the finally obtained result better conforms to the actual situation, and corresponding data support can be provided for actual production. 本发明公开了一种深层油气储层固相生成与堵塞损害预测方法，属于油气藏开发技术领域，本方法包括如下步骤；根据两种反应物的质量平衡方程、反应速率的动力学方程和
