摘　　要：本文对凹陷内隐蔽圈闭的形成机制、控制因素、类型及分布特征进行了探讨。研究认为:早期隐伏断层、中晚期层间断层及其岩性、不整合面等是泌阳凹陷隐蔽圈闭形成、分布的主控因素。泌阳凹陷中存在隐伏构造型、层间构造型、浅层不整合型、岩性型、基岩裂缝等多种类型的隐蔽圈闭。研究这些圈闭对深入进行泌阳凹陷的勘探开发有重要意义,而更重要的是对邻区地质特征的研究有指导、借鉴意义。This paper deals with the mechanism of formation of the subtle traps in Biyang sag, their controlling factors, types and their distribution. It is considered that early subtle faults, middle-late interstrata faults as well as lithology and unconformity surfaces are the main controlling factors in their formation and distribution of these traps. In Biyang sag there are various trap types, such as subtle structural type, interstrata type, shallow unconformity type, lithologic type, and basement fracturing type…etc. A detailed study of these traps will be significant in the further exploration of oil fields in Biyang sag and give an important reference to the study of the geologic features of neighbouring regions.
