泌阳凹陷隐蔽油气藏分布特征与勘探方法

论述了泌阳凹陷先断后陷再萎缩是其形成隐蔽油气藏的地质基础，根据凹陷构造与沉积特征分析限隐蔽油气藏的分布规律，在前人的研究的基础上，依据油气藏（圈闭）的成因隐蔽性及储集层的敏感性，将凹陷隐蔽油气藏（圈闭）分为五类，最后，针对泌阳凹陷不同区带具有不同油藏分布的特点，提出了相应的勘探方法和思路。

Distribution features and exploration method of subtle pool in Biyang sag

It is discussed that fracture?depression?shrink in Biyang sag is the geological basis of forming subtle pools (traps). Distribution rules of these pools are analyzed based on the structural and depositional features of the sag. The pools may be divided into five classes according to the concealment of origin and sensitivity of controlling the reservoirs of oil?gas pool on the basis of the research of our predecessors. At last, the relevant exploration methods and the train of thought are put forward in accordance with different distribution properties of the pool at different zones in Biyang sag.
