世界特提斯构造域是一个巨大的油气富集带,分布着世界上一些著名的特大含油气盆地,如波斯湾盆地、北高加索油区、苏尔特盆地等。西藏特提斯构造域油气勘探程度较低,根据地面石油地质资料,该区的石油地质条件较差,推测地下石油地质条件应好于地表。西藏特提斯构造域与世界其它地区特提斯构造域具有相似的大地构造背景、沉积环境和烃源岩发育特征。西藏特提斯构造域油气储层物性较差、燕山晚期及喜山期的构造变动比较强烈,使该区的油气藏保存条件较差。因而,在西藏特提斯构造域油气勘探中应以寻找中小型油气田为主。
The Tethyan tectonic domain in the world is a huge oil and gas-rich belt with some of the world’s most famous petroliferous basins, such as the Persian Gulf Basin, the North Caucasus oil region and the Sirte Basin. Tetsi Tectonics in Tibet has a relatively low level of oil and gas exploration. According to the petroleum geological data on the ground, the petroleum geology in this area is poor. It is presumed that the geological conditions of underground petroleum should be better than the surface. Tethys tectonic zone in Tibet has similar tectonic setting, sedimentary environment and source rock development characteristics as the other Tethys tectonics in the world. Tethys structural reservoirs in Tibet have poorer physical properties, structural changes in late Yanshanian and Himalayan periods are relatively strong, and the reservoirs in this area are poorly preserved. Therefore, in the Tethys tectonic oil and gas exploration in Tibet, we should look for small and medium-sized oil and gas fields.
