摘要
In this paper, the fault facies of discrete structures, membranes and lenses are divided into different subtypes in the carbonate outcrop. The discrete structures of the carbonate outcrop are characterized by the development of slip surface, fracture band, and deformation band. There exist three types of slip surface, i.e., straight intercept type, curved fluctuate type and gradation band type. Fracture bands, developed in the damage zone with insignificant filling, are ideal migration channels. It is necessary to deal with them separately because different grades of fault facies exert different effects on the reservoir and fluids.
