The lower part of Xingouzui Formation of Mawangmiao area is an important producing pay and profitable range to find lithologic hydrocarbon reservoir in the future. Based on the synthetical analysis of cores description, thin section analysis and logs, and combined with sedimentary marks of lithology, paleoclimate, sedimentary structure, and so on, the lower segment of Xingouzui Formation is ascertained shallow water delta-shore-shallow lacus depositional system, and is further divided into subfacies as follows: delta front, prodelta, shore-shallow lacus, etc. and several microfacies. Provenance analysis results indicate that the study area is controlled by northeastern Hanchuan provenance and northwestern Hanshui provenance, the study area develops two lobate deltas of NE-SW and NW-ES distribution, especially the NE-SW delta develop more widely.
