【摘要】 南阳凹陷边界断裂带是油田勘探的薄弱地区,也是油田下一步勘探的重点区域。通过建立研究区层序地层格架,在南阳凹陷边界断裂上利用地震资料及测井约束反演寻找小型砂体并刻画其特征,为下一步的勘探指明了方向。该地质与地球物理紧密结合的研究方法,对指导南阳凹陷以及中国东部其它相似断陷湖盆隐蔽油气藏的勘探,具有一定的借鉴意义。更多还原

【Abstract】 The boundary fault zones of Nanyang Sag are characterized by weak exploration,and also are the important exploration area for the further exploration.Based on the sequence stratigraphic framework,small sand bodies are identified along the boundary fault zones and the characteristics are described by using seismic data and logging constrained inversion,which indicates the direction for the next step of exploration.This method is significant for the subtle reservoirs exploration in NanyangSagand other similar fault depressed lacustrine basin in the east ofChina.更多还原
