Application of high resolution sequence stratigraphy in Fuyu reservoir of Yumin area

The stratigraphy, high-resolution sequence stratigraphy is based, and based on core, logging and seismic data synthetically, the organic combination of seismic data and drilling data analysis, there are one long-term cyclic sequence boundaries(SB1), and two lake flooding surface(FS1 & FS2)be distinguished in the study area. Then combined with sedimentary cycle characteristics, the study area may be divided into two long-term cycles (the equivalent of three grade sequence), and six mid-term cycles (the equivalent of four grade sequence) and 17 short term cycles (the equivalent of five grade sequence), which structure high resolution sequence stratigraphy of Fuyu reservoir in Yumin area, and lay the foundation for the study of sedimentary microfacies and the study of accumulation rule.
