    Abstract：In recent years, carbon capture utilization and storage (CCUS) technology becomes mature gradually, and relative projects, such as CO2-EOR, grow in number or quantity continuously. However, CCUS legal and regulatory frameworks are still in an exploratory stage throughout the world. Only a few of developed countries, such as the United States, Canada and Norway, have formulated laws or regulations associated with CCUS technology. CCUS technology will play a very important role in CO2 emission reduction in China. But up to now, there is no concrete legal framework for regulating a large-scale CCUS deployment in China, which results in CCUS projects being in "special rules for specific project" situation. This situation has hindered the scale-up of CCUS projects. Analyzed and reviewed are laws and regulations relative to CO2 well abandonment published at home and abroad, including plugging of wells and testing methods, etc. The results can provide basis and guidance for well abandonment services in CCUS projects, and also can provide reliable reference for establishing laws and regulations for well abandonment of CO2 geological utilization and storage in China.
