Reservoir-cap combination optimization and assessment of CO2 geological storage in East China Sea shelf basin
摘要
Abstract
The East China Sea shelf basin,the largest offshore sedimentary basin in China,is recognized as an ex-ceptional site for geological CO2 storage due to its substantial storage potential,proximity to carbon sources,and advanced exploration maturity.In this study,we investigated the basin's structural and sedimentary geological conditions and established assessment criteria for reservoir-caprock layers by integrating drilling and seismic data,thereby optimizing reservoir-caprock combinations and delineating favorable zones.Results demonstrate that the Paleocene strata in the Oujiang Sag and the Oligocene-Miocene strata in the Xihu Sag exhibit favorable geologic-al conditions for CO2 storage.Vertically,the distribution of reservoir-caprock combinations differs between the eastern and western regions.The eastern basin hosts predominantly in the Oligocene and Miocene sequences,while the western basin in the Paleocene and Eocene sequences.Horizontally,favorable zones in the eastern basin clustered within the Xihu Sag,whereas the western basin focused in the Oujiang Sag.In the southern basin,favor-able zones distribute along the western slopes of structural units.This study presents the first targeted assessment of CO2 storage potential in the East China Sea shelf basin to identify optimal reservoir-caprock zones by combin-ing sedimentary distribution patterns.The findings provide critical geological insights and practical references for implementing offshore CO2 storage strategies in East China.关键词
