中文摘要：

在海洋的碳酸盐和他们的主机的 87Sr/86Sr ，方解石的 18O 和 13C 比率，白云石，石膏充满 vugs 和裂缝从 Sinian 摇到中间三叠纪，被采用跟踪可能的来源和与烃的开发有关的关键液体的移植路径，烃保藏状况然后进一步被讨论。基于 paleo 液体，形成水的性质和变丑紧张等等，全面研究显示在 Shizhu 复向斜地区和 Fangdoushan 复背斜地区的保藏条件在中央 Yangtze 是最占优势的。在 Shizhu 复向斜地区的液体系统的三个集合被识别。很少液体交换都不发生在之间上面 -- 中间的液体系统和更低的液体系统，二个独立保藏单位因此发展了。两二叠并且以上面的保藏单位和 Sinian 的 Dengying 形成三叠纪并且更低以更低的保藏单位寒武纪有好保藏条件。在在西方的湖北和湖南位于 Huaguoping 复向斜地区的更低的协会( Z-S )的保藏条件以另外的构造单位比那好，在当孤立间隔的液体被破坏时，在更低的协会的液体越过阶层垂直地移居了的地方，地区性的封口是不在的，为烃累积的保藏的条件完全被破坏。保藏条件是逐渐地从到总体上的西方的湖北与东方重庆的西方的江西和湖南更有利。

英文摘要：

^87Sr/^86Sr, δ^18O and δ^13C ratios of calcite, dolomite, gypsum filling vugs and fissures in marine carbonates and their host rocks from the Sinian to the middle Triassic, are employed to trace the possible source and migration path of key fluids related to development of hydrocarbon, hydrocarbon preservation condition are then discussed further. Comprehensive research, based on the paleo-fluid, the property of formation water and the deformation intensity etc., indicates that the preservation conditions in the Shizhu synclinorium zone and Fangdoushan anticlinorium zone are the most predominant in the central Yangtze. Three sets of fluid systems in the Shizhu synclinorium zone are identified. Little fluid exchange occurs between the upper-middle fluid system and the lower fluid system, so two independent preservation units have developed. Both the Permian and the Triassic in the upper preservation units and the Dengying Formation of the Sinian and the lower Cambrian in the lower preservation units have good preservation conditions. The preservation condition in the lower association （Z-S） located in the Huaguoping synclinorium zone in the western Hubei and Hunan is better than that in other tectonic units, where the fluids in the lower association migrated vertically across strata when the fluid isolating intervals were destroyed, the regional seals are absent and the conditions for the preservation of hydrocarbon accumulations are totally destroyed. The preservation condition is increasingly more favorable from the western Jiangxi and Hunan to the western Hubei ＆ eastern Chongqing on the whole.
