Temporary plugging agent can divert the fracturing fluid into lower permeability layer by plugging higher permeability layer, then the uniform stimulating in reservoir can be achieved. Temporary plugging agent had the properties of high plugging strength, no damage to formation and simple construction. In this paper, according to the different mechanism in plugging reservoir fracture, temporary plugging agents were divided into four types which included particle type, fiber type, gel type and compound type. Furthermore, various temporary plugging agents were reviewed from the aspects of the temporary plugging mechanism, technical characteristics and application.
