Abstract: Since the concept of reservoir architecture is proposed, the studies have gradually ranged from river deposit system to other various systems. In view of meandering river system, the quantitative studies are achieved for abandoned channel location, configuration interface lateral accretion body’s number and correlation shape?sizing of point bar. For braided river system, the combination relationship between channel and mid?channel bar as well as the model of inner architecture of mid?channel bar are gradually developed. For alluvial fan system, its reservoir architectural grading and identifying model have become the main targets. And for delta front system, the detailed configuration element classification of underwater distributary channel inner accretion body and the mouth bar inner accretion body is focused on. Finally, this paper presents the existing problems and prospects in reservoir configuration studies for different deposit systems. It is concluded that developing configuration models that are more suitable for available geological recognitions, determining the dynamic response features of the reservoir configurations and their relations with the well patterns will be the trend to such researches
