摘要： 应用“层圈闭”和“块围闭”的概念对塔里木盆地已发现和钻探的圈闭进行了统计分析，提出了塔里木盆地的圖闭分类方案。将巳发现的圈团划分为构造图闭、非构造圈团和复合圈闭3大类，包括6个亚类和18个小类。分析了各构造区的圖闭的形成条件及发育分布特征。塔北隆起的圈闭主要沿断裂带分布，圈团的主要层位为新第三系、老第三系、白垩系、三叠系、石炭系和奥陶系，国闭类型以背斜型和断背斜型为主，兼有潜山型和岩性圈闭。塔中地区的圈闭主要分布在中央断垒背斜带及其南北斜坡区，圆闭主要分布层位为奥陶系和石炭系，奥陶系以潜山型圈闭为主，多分布在南斜坡区:石炭系以背斜及断背斜型圈闭为主，分布在全区。库车坳陷主要由。中新生界成排成带的地面构造和规模大、结构复杂的地下构造组成。在已获油气流的圈闭中，背斜圆闭占54%，断块断鼻圈闭占22%，岩性圈闭占15%。

Abstract: This paper statistically analyzed the discovered and drilling traps by applying the concepts of "bed trap"and aroided into three major tyes (structu Tarim basin.The discovered traps).six subtypes traps were and egheen minor types.The formation structural al and combination analyzed.The traps condition, distributed along the main fault zone,developed in Neogene.in Tabei uplit were mainly.dominated by anti-The Cretaceous, Triassic, Catonieroues and Ordovrin.and, nd lithologic trap.Paleogene, faulted-anticline type, as well as buried hill type an lithologic type and distributes in central horst anicine 2oe and its NS sos taps in Tazhong area mainly (dominated by buried hll type trap faulted anicline trpe taps and distributed ted in south slope) ocurring in Ordovician and Carboniferous (dominated by anticline type and rface structure in row and large which oil and gas flow scale com-, in nbut n a are.The Msoic Cenoisu depressiojn.Of traps 22%，and plex subsurface structure mprise Kuqa were discovered, anticline traps fkes4 faut block and faul nose traps lithologic traps 15%.
