Abstract:Laizhouwan Sag,a Cenozoic marginal sag located in the southeast of Bohai Sea,is characterized by complex hydrocarbon accumulation.In order to solve the diversity and complexity of hydrocarbon accumulation,tectonic evolution characteristics are studied based on the analysis of fault system and trap characteristics,and reservoir control effects are defined.Based on our research,KL16-A structure went through four evolutionary stages:early faulted stage of E1-2k~E2s4,strong faulted stage of E2s3,fault-depression stage of E3s1-2~E3d,and depression and Neotectonics stage of N~Q.The imbalance subsidence in periods led to the different evolution of the eastern,central and western blocks,the development of strike-slip and extensional fault systems,and the obvious different resi-dual thickness of Paleogene.The different tectonic evolution controlled reservoir characteristics including the development and migration of hydrocarbon generating center,trap formation and type,sedimentary type and reservoir distribution,and hydrocarbon accumulation model.
