Abstract: Miall architectural structure analysis is applied to study the reservoir architecture structure of the subbed of Es234 of Shengtuo oil field. Thirteen types of lithofacies are distinguished through core observation. Based on the observation, correlation of connectingwell sections and recognizition of well logging curves, with the conception of stratification, six scales of bounding interfaces are defined. Based on the recognization of lithofacies and the classification of sequences, seven kinds of structures are identified, and they are channel sediments(CH), channel retention sediments(CHL), channel bar(CB), fallsiltseam(FS), natural levee(LV), crevassesplay (CS), Overbank fine sediments(OF). And finally, the planar and sectional assemblage models of architecture structure of 34 sand body are established. Channel filling(CH) and channel bar (CB)are the main architectural elements in the plane and three hierarchies are divided in the section.

Key words: architectural structure analysis, lithofacies, bounding interface, architectural element
