塔里木盆地经历了7个构造演化阶段,受9期构造运动的影响,发育了多个不整合面。经多年勘探,目前已探明和发现了众多的海相成因油气田(藏)。这些海相成因的油气主要富集在奥陶系碳酸盐岩与石炭系、三叠系、侏罗系砂岩储集层中,它们主要来源于寒武系和中-上奥陶统两套烃源岩。这两套海相烃源岩在盆地中共构成了8个供烃中心,这些供烃中心基本控制了盆地油气田(藏)的分布(图1)。
The Tarim Basin experienced seven stages of tectonic evolution, affected by 9 tectonic movements and developed a number of unconformities. After years of exploration, many marine oil and gas fields have been discovered and discovered at present. These marine-derived hydrocarbons are mainly enriched in Ordovician carbonate and Carboniferous, Triassic, and Jurassic sandstone reservoirs, mainly derived from two sets of Cambrian and Middle-Upper Ordovician Source rock. These two sets of marine source rocks form eight hydrocarbon supply centers in the basin. These hydrocarbon supply centers basically control the distribution of oil and gas fields in the basin (Figure 1).
