摘　　要：东濮凹陷黄河南低含油丰度区由于烃源岩品位低、构造复杂、储盖组合条件差等原因 ,油气分布具有近源的构造翼部富集、断块控油、油气藏小而分散、圈闭充满度低等特点 ,与北部高含油丰度区有很大差别。针对这一特征 ,东濮凹陷黄河南低含油丰度区的进一步勘探应在精细勘探目标解释的基础上 ,以断块群为评价对象、以定向井为手段、走滚动勘探开发的道路。In low oil-abundance area to the south of Yellow river in Dongpu sag,oil and gas distributions are characterized by hydrocarbons to be accumulated in near-source limbs of structures, fault blocks controlling oil accumulation, oil/gas pools being small and scattered, and low level of trap fullness, due to poor quality of source rocks, complexity of structures and poor combination of reservoirs and seals. It is quite different from the high oil-abundance area in the north. Progressive exploration and development should be carried out in the low abundance area in the future, on the basis of careful interpretation of exploration targets, and taking fault block groups as appraisal objects and directional drilling as a measure.
