Abstract: The sequence boundary of Paleogene in Jiyang Depression could be divided into six construction styles, i.e. the truncated overlap style, the truncated parallel style, the parallel overlap style, the top overlap style, the parallel style, and the compound style. Taking T6', one of the Paleogene sequence boundaries in Jiyang Depression, as an example, genetic model of lithologic traps is established based on the sequence boundary construction styles, and favorable zones of lithologic traps under the control of sequence boundary construction styles are predicted by using the criterion of “six factors” (the changes dynamics of sequence boundary, sequence boundary sand control, the properties of reservoir sandstones, hydrocarbon generation and expulsion, sedimentary environment, and sequence boundary reservoirs control). The practical application indicates that this method has obvious technology advancement and it will definitely increase the accuracy of prediction and improve the ability and level of exploration deployment

Key words: sequence boundary construction styles, lithologic traps, sequence boundary sand control, sequence boundary reservoir control, favorable zone prediction, Jiyang Depression
