摘　　要：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 are well developed in Tarim Basin and the types are various. The traps include: overlap traps and cut--blocking traps relating to unconformity;buried-hill traps relating to paleo--uplift; lithologic traps relating to the sedimentation of river, delta and shallow lake. The formation of the non--stractural traps was controlled by paleostructural framework. The traps formed primarily in the Hercynian, Indo--China and Yenshan Periods and were distributed in paleouplift and paleoslope belts,thus constituting a paleouplift--buried hill--lithologic trap series.
