Salt tectonic activity controlling on hydrocarbon accumulation:A case of the Lower Congo Basin
摘要
Abstract
Salt structure plays an important role in controlling the hydrocarbon accumulation,and many oil-rich basins are rich in salt structure.From the perspective of petroliferaceous basin analysis,taking the Lower Congo Basin in the east coast of the South Atlantic Ocean as the research object,based on the theory of structural geology,sedimentology and hydrocarbon accumulation dynamic,the paper aims to analyze the control effect of salt structure deformation on salt-related oil and gas accumulation,on the basis of the deformation characteristics and evolution process of salt structure.Based on the interpretation of 2D and 3D seismic data,four major salt structures,including salt roller,diapiric salt,canopy salt and missive salt,were identified in the Lower Congo Basin,and the deformation characteristics of various salt structures and the tectonic characteristics of their overlying strata were defined.Finally,based on the analysis of the influence of salt tectonic deformation on the static factors for hydrocarbon accumulation such as source,reservoir and trap,and the dynamic processes for hydrocarbon accumulation such as the evolution of trap,hydrocarbon migration and preservation,the dynamic hydrocarbon accumulation model of the Lower Congo Basin was established,aiming to guide the future oil and gas exploration in this basin.关键词
