摘要： 台北凹陷隐蔽圈闭的主要类型为岩性型和地层型。在对这两种圈闭的形成因素、条件及其特点进行论述的同时,着重根据台北凹陷内各区带的砂泥组合特征及其与构造的匹配关系对符合隐蔽圈闭条件的区带作一评判。由于隐蔽圈闭的形成对地质因素要求极其严格,几乎是缺一不可,所以大部分区带都难以形成这种圈闭。在分析了台北凹陷的沉积、构造发育史的基础上指出,在葡萄沟段有可能形成岩石侧变圈闭；在胜北、温吉桑及十三间房等构造带有些形成地层型圈闭；在近物源区有可能形成古河道砂岩岩性圈闭及透镜状岩性圈闭。

Abstract: The subtle traps of lithological type and stratigraphic type are found in Taibei sag of Turpan-Hami basin.The authors discussed the factors, conditions and features of these two traps, and evaluated the areas conformed to con-ditions of them,based on sandmud combination characters and their filling relations to the structures for each area ofTaibei sag. The result shows that these traps are difficult to be shaped in most part of the area,due to their special de-pendence on the geological factors. When some of the area are ready to be denied for poor potentials,predictions forfinding potentials for the two types of subtle trap in Taibei sag are made again.
