Zusammenfassung:The invention discloses a carbonate rock acid fracturing effect quantitative evaluation method. The method comprises the following steps of: firstly, performing acid etching on a rock plate crack wall surface by adopting a rock plate acid etching simulation device, and measuring groove depths of acid liquor at an inlet and an outlet of a rock plate; then measuring the quality of the rock plate before and after acid etching; and finally comprehensively considering the depth of an acid etching groove of the rock plate to obtain an acid etching groove form factor. The acid etching groove form factor of the rock plate is compared with the form of the crack wall surface and crack flow conductivity, a good corresponding relation exists between the acid etching groove form factor of the rock plate and the form of the crack wall surface and the crack flow conductivity, and the method can be used as a quantitative evaluation method for the acid fracturing effect of carbonate rock. The method is simple in thought and h
