Based on the conduit system elements analysis and the study of the special styles in Jiyang Depression, combined with the mechanisms analysis of faults, fracture, frame sands and the unconformity beds, this paper illustrates the static style and the dynamic evolvement of the conduit systems in the rift basin. This paper points out that the different conduit system styles are located in different structure belts and different development stages. All the conduit systems constitute the “multiple-conduit systems network” in rift basins. This paper points out the conduit systems and their distribution rules control the classification, stratification and distribution of reservoirs in the manners of section and plane.
