Abstract: In conventional acidizing to low permeability reservoir, the formation will be damaged again owing to the unthorough flow-back of the spent acid, so foamed acid has been used. The per formance and influence factors of the foamed acid have been in troduced detailed in this paper, and some successful experiences in field have been listed, so that its excellent performance of can
be illuminated farther.

Key words: foamed acid, low permeability reservoir, reservoir improvement
