Objective To investigate in depth the mechanism of temperature-sensitive damage to reservoirs during thermal recovery and provide a theoretical basis for effective reservoir protection. As a result, during the thermal recovery process, the temperature shock will cause the change of rock minerals, the dissolution and the wettability change. At the same time, it will work synergistically with other reservoir damage to produce synergetic effect and greatly damage the reservoir. Conclusions In the laboratory research, attention should be paid to the study of reservoir lithology, lithofacies, formation water chemistry and the physical properties of crude oil, so as to provide a theoretical basis for selecting proper production technology and production system
