摘　　要：泌阳凹陷北部斜坡带由构造-沉积背景控制油气区域分布特征,构造特征为一鼻状构造和断裂非常发育的断裂带,鼻状构造主体是油气主要聚集带;成藏模式受输导体系控制,油藏具有南北分带、东西分块的多样性,断裂系统控制区块内油气富集和分布;现阶段滚动增储的主要潜力方向是微幅度构造油藏、隐蔽构造油藏、断层-岩性油藏,备较为有利的油气成藏条件;根据区块油藏特点和项目开发方式,采用现金流量法对泌阳凹陷北部斜坡带投资效益进行综合评价。The distribution characteristics of oil and gas in the northern slope zone of Biyang Depression are controlled by the tectonic sedimentary background.The structural features are a nose shaped structure and a fault zone with well-developed faults.The main body of the nose shaped structure is the main accumulation zone of oil and gas;The reservoir formation mode is controlled by the transport system,and the reservoir has diversity in north-south zoning and east-west blocking.The fault system controls the enrichment and distribution of oil and gas within the block;At present,the main potential directions for rolling reservoir expansion are micro amplitude structural oil reservoirs,concealed structural oil reservoirs,and fault lithologic oil reservoirs,with favorable conditions for oil and gas accumulation;According to the characteristics of block reservoir and project development mode,the cash flow method is used to comprehensively evaluate the investment benefit of the Northern Slope of Biyang Depression.
