Abstract:

According to the genetic sequence interfaces and regional tectonic movement,Tertiary strata in Nanpu depression can be divided into 7 super-sequences,missing only the 2nd super-sequence by comparison with other basins in Bohai Gulf. Each of these super-sequences generally constitutes a complete source-reservoir assemblage.The deep lacustrine mudstone in the middle sequence set is a relatively good source rock, and the wedge-shaped, coarse-grain sedimentary system in the lower sequence set is a good reservoir rock. So, the most prospective position for deep hydrocarbon reservoir exploration might be the part of coarse-grain deposition system in the lower position,which is extending to the central part of the basin.

Key words: sequence interface, Tertiary, hydrocarbon reservoir, oil source rock, reservoir, Nanpu depression
