| 摘 要： | 从五号桩洼陷的构造演化及特征分析入手，将洼陷内主要储集层分为浊流、水下冲积扇、滩坝和三角洲等五种沉积类型。该洼陷油气藏类型较多，可划分为岩性、构造、地层、复合等四种，并针对其特点进行详细的论述；最后，分析了洼陷内三类次级构造单元包括深洼带、斜坡带和中央低突起的油气成藏规律。

| Abstract: | The main reservoirs in Wuhaozhuang subsag may be divided into five sedimentary types of turbidity current, fan?delta, underwater alluvial fan, beach bar and delta from the analysis of structural evolution and characteristics of it. Many types of oil?gas accumulation exist in the subsag, which may be classified as lithological, structural, stratigraphic and compound one, and are expounded according to their own properties. At last, pool?forming rules of third?class secondary structural unit including deep depression zones, slope belts and central low arch are analyzed. |

| Keywords: | Zhanhua sag Wuhaozhuang subsag structural characteristics depression zone slope belt central low arch pool forming rules |
