摘要基于Miall储层构型研究思想，结合岩心、测井、测试等资料，对乌南油田砂坝砂体储层构型界面特征进行了研究，确定了储层构型界面识别标志；在此基础上，将砂坝内部构型分为坝主体和坝侧缘，同时通过动、静态结合，明确砂坝外部构型存在孤立、视连通、左侧向叠置和右侧向叠置4种模式；纵向上发育湖退（进积）和湖进（退积）两种砂体发育模式。坝主体是主力储层，具有良好油气显示；坝主体分布面积大、出现频率高为油气有利区域。

Abstract： Based on the Miall reservoir architecture theory，and through core，logging，testing data，characteristics of reservoir conformation boundaries of beach-bar sandstone bodies in Wunan oilfield were well analyzed，and reservoir architecture interface identification was determined. Inner architecture of sand bar can be divided into sand bar body and sand bar margin. Meanwhile，combining static and dynamic analysis，outer architecture of sand bar can be classified into four modes，such as isolated mode，apparent connected mode，left superimposed mode and right superimposed mode. In the longitudinal direction，two kinds of sand distribution patterns were well developed，like progradation pattern and retrogradation patteren. Sand bar body is main reservoirs of this area，and has good oil and gas shows. Large distribution and high frequency of sand bar body are favorable for oil and gas exploration and development.

Key words： The shore-shallow lake Beach bar Reservoir architecture Sand bar body San bar margin Sand connecting mode
