Evaluation of 3D Hydrocarbon Migration System in Baodao Sag in the Deep-water Area of Qiongdongnan Basin
摘要
Abstract
The dominant migration path and migration direction of the Baodao Sag,were identified based on drilling and seismic data using seismic interpretation,paleostructure restoration,oil and gas migration and accumulation modeling,3D geological modeling,and other technological approaches.Four faults with four levels,four sets of framework sand bodies,and four main structure ridges were identified in the Baodao Sag.The system of source rock-migration system-reservoir-trap in the Baodao Sag has been established,and the migration systems have been classified into three types:the T type,ladder type,and restricted meshwork-carpet type.The southern and northeastern step-fault zones are characterized by ladder type migration systems,while the Songnan low uplift and northern slope zones are characterized by restricted meshwork-carpet type systems.The migration simulation shows that the southern step-fault zone,northeastern step-fault zone,and Songnan low uplift front tectonic zone are the dominant migration directions,which are mainly characterized by vertical and lateral migration.The selection of favorable zones indicates that the southern step-fault zone is the most favorable zone,which has the configuration features of "near source,fault-sand-ridge ladder type migration,submarine fan and fan delta reservoir,and fault block-lithologic trap."关键词
