Huanghua Depression, which is located in north-central Bohai Bay basin, belongs to North China basin in structure. It has experienced five tectonic movement stages of Caledonian, Hercynian, Indo-Chinanian, Yanshanian and Himalayanian, and developed four periods of basin-forming function, which are mutually superimposed and reformed in the longitudinal direction. The hydrocarbon rocks in the deep region have experienced evolution process of shallow deposit in early and middle periods and deep deposit in late period, and have a great potential of secondary hydrocarbon generation. Pool-forming types posses a variety of combination characteristics, containing paleo-storage of neogeneration, paleo-storage of paleo-generation, meso-storage of paleo generation, meso storage of neo-generation and so on. This study shows that the region has great potential of deep resources, and exploitation directions are proposed as paleo-storage of neogeneration in buried hills, meso storage of neo-gation in buried hills of central uplift belt, primary reservoir of paleo-storage of paleo generation.
