摘要
Based on the observation of core as well as the interpretation of well-log and seimic data,and on the theory of classical sequence stratigraphy by Vail, the sequence stratigraphy of Yingshan Formation is studied. The Yingshan Formation in central uplift can be divide into four third-order sequences. Named SQ1-SQ4 from bottom to top,and only transgressive system tract and highstand system tract were developed. The study on the reservoirs and sequences indicated that the sequence boundaries play an important role in reservoir development. It controlled the distribution of reservoir in Yingshan Formation and the reservoir were mainly developed in HST and experienced the karstification which modified the quality of reservoir.
