Through literature research, the unplugging mechanism of various wellbore unplugging fluids was analyzed, and the application progress, advantages and disadvantages of various types of commonly used wellbore deplugging fluids were summarized. The research progress of new deplugging working fluids such as organic deplugging working fluid, organic slow-release microlactic acid deplugging working solution and composite deplugging working fluid was introduced. The problems existing in the preparation and practical application of plugging fluids were analyzed, and the development trend of unplugging liquids in the future was proposed. [ABSTRACT FROM AUTHOR]
