摘　　要：通过分析特提斯构造域东段区域地质和含油气盆地勘探开发基础数据,从板块构造演化入手,系统编制特提斯构造域东段沉积构造演化剖面图和生储盖组合剖面图,研究盆地演化阶段、叠合特征、油气成藏条件及油气藏类型,揭示中亚和中国西部前陆盆地演化和油气富集规律异同。研究表明:古亚洲洋、古特提斯洋和新特提斯洋控制了特提斯构造域东段的区域构造分带、盆地演化、盆地类型及油气成藏模式。根据古洋壳缝合线可分为北、中、南3个构造带,古生代以来多期微板块的拼贴,导致特提斯构造域东段含油气盆地演化分为3个演化阶段,早古生代伸展、晚古生代挤压、早中生代伸展和新生代挤压构造作用控制了研究区盆地的叠合演化,发育下古生界、上古生界和中生界3套区域分布的优质烃源岩和下古生界、上古生界、中生界和新生界4套储盖组合,形成多种类型的油气藏。Through analyzing the regional geology and basic exploration and development essential data of the petroliferous basins in the eastern segment of the Tethyan tectonic,the thesis systemic profiles the sedimentary tectonic evolution profile and the source-reservoir-cap of the eastern segment of the Tethyan tectonic. Based on the study of the tectonic evolution of plate,and studying basin development stagebasin Superimposing Characteristics,hydrocarbon accumulation condition and types of reservoirs,and revealing the similarities and differences in evolution and hydrocarbon enrichment rule of the foreland basins present in the Central Asia and Western China.The study suggests that,the tectonic zonation,basin evolution,basin type and hydrocarbon distribution in the eastern segment of the Tethyan tectonic domain are controlled by the Paleo-Asian Ocean,the Paleo-Tethys Ocean,and the Neo-Tethys Ocean. And it can be divide into The northern,middle and the southern tectonic belts,and As a result of the connection of multi-stage microplates since Paleozoic,the evolution of the petroliferous basins in the eastern segment of the Tethyan tectonic domain can be divided into three stages,the superposition evolution of research basin area is controlled by early Paleozoic extension, Late Paleozoic compression, Early Mesozoic extension and Cenozoic compression,and developing abundant hydrocarbon resources of the Lower Paleozoic,Upper Paleozoic and Mesozoic and forming four types of superimposed basin of Lower Paleozoic,Upper Paleozoic,Mesozoic and Cenozoic. Finally the multiple types of reservoirs were formed.
