关于“隐蔽油气藏”概念的若干思考

Discussion on proposition and definition of subtle oil-gas reservoir

根据对国内、外大量文献的调研结果,对隐蔽油气藏的涵义和特征进行了系统论述。隐蔽油气藏(隐蔽圈闭)是一种因勘探活动而提出的实用性术语。对隐蔽油气藏开展的任何石油地质理论研讨均应首先研究各种油气藏的圈闭成因类型,即针对它所涵盖的各种油气藏圈闭成因类型来进行石油地质研究。提出了新的非构造油气藏分类方案,以便更适应隐蔽油气藏勘探的需求和加大理论应用的便利性。

A large number of literatures on subtle and obscure traps at home and abroad were investigated. The definition and characteristics of subtle oil-gas reservoirs were systematically discussed. Subtle oil-gas reservoir or trap is a practical term proposed for describing exploration activities. Any discussion on theory of petroleum geology about subtle oil-gas reservoir should be firstly started from the classical types of all kinds of traps included in the subtle oil-gas reservoir. That is to say, petroleum geology research should be conducted around the type of trap included in the subtle oil-gas reservoir. A new classification method for non-structural oil-gas reservoirs was proposed to meet the demand of exploration for subtle traps and to enlarge convenience of theory application in China.
