Abstract: Based on the investigation of comprehensive literatures about the asphaltene deposition caused by CO2 injection in reservoirs at home and abroad, the development of experiments and numerical models are summarized and their advantages and disadvantages are compared, and the properties of asphaltene deposition are analyzed. Finally, the suggestions of related directions of the researches are proposed in this paper.
