To study the unconformity types of Dongying Formation in the northern part of Dongpu sag, and their effect on transporting, isolating and accumulating for hydrocarbon. Logging, coring and seismic data are comprehensively used to study, the unconformity type of Dongying Formation in the northern part of Dongpu Sag in detail, and its significance in petroleum geology is discussed. According to the study, in terms of hydrocarbon transporting and accumulation, the unconformity is classified into three types, which are lateral transporting, vertical leaking, and isolating model. The lateral transporting unconformity has the help for the hydrocarbon migration and accumulation of the Dongying Formation; the isolating unconformity that develops in large-scale resists the hydrocarbon′s vertical migration and leaking of Dongying Formation, and disturbs the hydrocarbon accumulation in the shallower strata on it, which is the main reason why the large scale hydrocarbon reservoirs have not been discovered in Guantao and Minghuazhen Formation nowadays. microsoft-com:office:office" />
