| 摘 要： | 砂体和断层是泌阳凹陷油气运移的基本要素．砂体与断层匹配形成三类油气运移输导体系：砂体单因素输导体系发育于凹陷南部．以油气沿砂体侧向运移形成砂岩上倾尖灭圈闭油气藏为特征；断层单因素输导体系主要由东、南部边界断层构成．油气沿断层垂向运移在浅层形成次生油气藏；砂体一断层复合输导体系主要发育于凹陷北部，受断层性质、断面产状、形成时期、以及与砂体和鼻状构造的匹配关系的影响。油气输导体系从根本上决定了油气藏类型和分布规律．南部以各类砂岩上倾尖灭圈闭油气藏最为发育，南部边界断裂附近是寻找浅层次生油气藏的有利区带．北部斜坡带发育复杂的断鼻断块油藏。

| Abstract: | The mixed sedimentary genesis of Es_4 terrigenous clastics and carbonates in Bonan Depression is discussed. According to the mixed modes and sedimentary background, the mixed sediments in the studied area are divided into fan deltaic deposit, braid river deltaic deposit, inshore-subsea fan deposit and lacustrine deposit. Their characteristics and distribution are discussed in detail, it is considered that the climate and sources are the main factors controlling the mixed sediments. On the basis stated above, the mixed sedimentary modes of Es_4 terrigenous clastics and carbonates is established. |
