The research progress of authigenic acid acidizing technology was comprehensively analyzed, and the acid-rock reaction characteristics of authigenic acid, the main acid-generating mechanism of authigenic acid, and the research progress of authigenic organic acid, authigenic hydrochloric acid, authigenic hydrofluoric acid and composite authigenic acids were introduced, the influence of the type of authigenic acid, hydrogen supply capacity, cost, retardation capability, corrosion inhibition capability and other factors on the field application of acidizing work fluid was analyzed, and the application of authigenic acid in acidizing operation was prospected. This study can provide a reference for the development, popularization and application of autogenic acid acidizing technology.

Key words: authigenic acid, retarded acid, deep acidizing, acid-rock reaction, acid-generating mechanism
