Seismic reservoir is a subdiscipline of reservoir geology developed based on seismic stratigraphy, sequence stratigraphy and seismic sedimentology, while clastic seismic reservoir is an important part of seismic reservoir and is the continued research and development of above-mentioned subdiscipline. The clastic seismic reservoir and the development of related subjects are briefly summarized, and the connotation, research contents and key technologies of clastic seismic reservoir are emphatically discussed. It mainly uses high resolution 3D seismic and production seismic data, as well as geological, logging and analysis testing data, making production members and single sand body as it’s ordinarily research targets, to describe the 3D spatial configuration of clastic reservoir semiquantitatively and quantitatively, to accurately determine the heterogeneity of inter-well reservoir and qualitatively predict the reservoir property and fluid features. Based on the above-mentioned research, the reservoir lithofacies model and physical propertymodels of porosity, permeability and saturation are established. Clastic seismic reservoir is applicable not only for every exploration stages, but also for the early development stage and the target evaluation implementation stage of progressive exploration, as well as the plan adjustment in the intermediary and later stage.
Key words： reservoir; physical property; Denglouku Formation; Changling Gasfield
