Temporary plugging and well-killing technology are widely used in well repair operations in oil and gas fields to solve the problems of well-killing fluid leakage，gas invasion，and high-pressure well failure during well repair. In this paper，the research progress of temporary plugging technology in well repair operations in my country was summarized，the research progress and application of different types of temporary plugging agents was focused on，and the advantages and limitations of various types of temporary plugging agents under different formation conditions was pointed out. Through the analysis of relevant literature，the application trends and future research directions of different types of temporary plugging agents were demonstrated，providing a reference for further research on temporary plugging and well-killing technology.
