///This paper describes the rock type, petrology characteristics, assemblage and distribution of reservoir for various types of reservoirs. The reservoir is mainly a set of carbonate depositions in Gaoyuzhuang Formation, Tieling Formation and Wumishan Formation of Mesoproterozoic and Neoproterozoic in North Hebei Depression and Xuanlong Depression, Yanshan Region. A set of clastic rock deposits at the bottom of Xiamaling Formation. Eleven kinds of reservoir types have been identified. The reservoirs can be roughly classified into four types according to the reservoir conditions, in which the good reservoir conditions are shown in the reservoir rocks of paleo-weathering crust, algal reef and quartz sandstone of barrier island foreshore.
