The invention relates to the field of oil and gas field development, in particular to an experimental system and experimental method for multi-round thermal compounding chemical huff and puff. The experimental system is mainly composed of an injection-production system, a model system and a monitoring system. According to the experimental system and experimental method, a three-dimensional physical model is designed according to a similarity criterion on the basis of a multi-round thermal compounding chemical huff and puff actual production process, the influence of steam, gas and a viscosity reducer on the mining effect is analyzed by utilizing real-time temperature data, real-time pressure data, crude oil properties and characteristics at each stage and the like, and the yield increasing effects of different mining modes are analyzed by recording the accumulated oil production in each stage. 本发明涉及油气田开发领域，尤其是一种多轮次热复合化学吞吐的实验系统及实验方法。本发明所述实验系统主要由注采系统、模型系统、监测系统三部分组成。本发明基于多轮次热复合化学吞吐实际生产过程，根据相似准则设计三维物理模型，利用实时温度数据、
