| 摘 要： | 分析了中扬子区海相地层油气成藏背景，研究了成藏有利区层序样式基本特征，预测了油气成藏有利区。认为在具备盖层条件的前提下，有利区应该具备的条件是烃源条件和储集条件配置关系良好。下古生界总体上保存条件优越，有利区主要位于湘鄂西、宜昌斜坡和江汉平原南部；上古生界总体上保存条件差异性明显，有利区主要位于渝东-鄂西区和江汉平原区。

| Abstract: | The author discusses the background for the marine stratigraphic oil and gas pool in the middle Yangtze plate. And he also analyzes the favourable area for the formation of oil and gas pool and its sequence patterns. If the capping beds exist, the conditions for the favourable place of oil and gas pool are good hydrocarbon source and reservoir beds as well as a good combination between them. As a whole, the Lower Palaeozoic strata develop a rather good preserving conditions, with the favourable place for oil and gas pool occuring in Western Hubei - Hunan, Yinchang slope and southern Jianghan plain. And the Upper Palaeozoic strata develop unevenly from place to place, with the favourable place for oil and gas appearing majorly in eastern Chongqin- western Hubei and the Jianghan Plain. |
