Geological characteristics and accumulation model of complex hydrocarbon zone of burial hill drape anticline-an example from gaoshangpu oil field in Nanpu sag

摘要

Based on analysis of characteristics of Gaoshangpu burial hill drape anticline zone, this paper discussed hydrocarbon accumulation characteristics and model in Gaoshangpu complex hydrocarbon zone by application of hydrogeological cycle analysis and theory of Abnormally Pressured Fluid Compartment, and pointed out that hydrocarbon with different properties in deferent reservoirs had been through deferent process of migration and accumulation.
