摘　　要：塔里木盆地东部具有古隆起、中拗陷、晚稳定的构造发育特征,震旦—寒武系碳酸盐岩生储盖组合好、烃源岩有机质丰度高、热演化程度高、构造和地层圈闭大、形成早、埋藏较浅,具备了形成大型天然气干气藏的地质条件,预测塔东是未来的大气区。The east part of Tarim Basin possesses structural features of early uplifting, mid-depression, and late stabilizing. Good source-reservoir-caprock assemblage, high organic matter abundance and strong thermal evolution of hydrocarbon source rock, large structural and stratigraphic traps which were formed early but buried shallow, provide the Sinian-Cambrian carbonate with all the geologic conditions of forming large dry gas reservoir. So it can be predicted that East Tarim would be a large gas.region in the future.
