The data of well bores, cores, well logging, seismic and paleontology in Qiongdongnan Basin were systematically analyzed. The sequence boundaries of the coal-bearing strata in Yacheng Formation were distinguished and the high-resolution strata sequence of Yacheng Formation was divided. The characteristics of lithology, lithofacies, logging and seismic reflection are very different in the upper and below the sequence boundaries.
