塔里木盆地非构造圈闭十分发育。有与不整合有关的起覆圈闭和削截圈闭；有与古隆起有关的潜山圈闭；有与河流、三角洲、滨浅湖等沉积作用有关的岩性圈闭。这些非构造圈闭的形成主控于古构造格局，主要分布于古隆起及古斜坡地带。海西期、印支－燕山期是塔里木盆地非构造同闭的主要形成期，构成以古隆起－潜山－岩性为主体的圈闭系列。 Non-structural traps in the Tarim Basin are well developed. There are overrun and cut-off traps associated with unconformities; buried hill traps associated with paleohighs; and lithologic traps related to sedimentation in rivers, deltaic, shallow-lying lakes, and the like. The formation of these non-structural traps dominated the paleotectonic pattern, mainly distributed in paleo-uplift and paleo-slope areas. The Hercynian, Indosinian and Yanshanian periods are the main non-tectonic closures of the Tarim Basin, forming a series of traps dominated by paleohigh-buried hill-lithology.
