摘    要:
亚洲特提斯域油气在地理上主要分布于西亚段南带,其次为西亚段北带、东南亚段中带,再次为中亚段。对古、中、新特提斯域的岩相古地理特征作了分析研究,并编制了相关的岩相古地理图。认为油气分布在盆地类型上主要与前陆盆地、克拉通边缘盆地相关,盆地形态主要与台地、环形坳陷、线形坳陷等沉积—构造环境相关,其成烃物质的沉积原构造环境多位于古赤道与45毅古纬度之间。提出盆地保存是盆地油气评价的先决条件。指出了亚洲特提斯域南带、中带和北带的油气勘探新领域。

Abstract:
The petroleum resiource of Asian Tethyan tectonic domain mainly distributes in the south part of west Asia,secondly in the north region of west Asia and in the middle southeast Asia, the last in central Asia. Geologi cal characteristics of lithofacies paleogeography in Tethyan realm is analyzed, and several corresponding maps of lithofacies palaeogeography are compiled. It can be seen that the majority of the petroleum reserves in foreland basins and pericratonic basins in the areas between the palaeoequator and the 45°palaeolatitude. The basin mor phology tends to be associated with the sedimentary-tectonic environments such as platforms, and ring and linear depressions. The preservation of the above-mentioned basins may be considered as a prerequisite to basinwide petroleum assessment. The authors also point out the mainly new domains of hydrocarbon exploration in the south zone, central zone and north zone of Asian Tethyan tectonic domain.
