东濮凹陷黄河南地区油气储层特征与形成条件

THE CHARACTERISTICS OF RESERVOIR FORMATIONS AND ITS FORMATION IN THE REGION SOUTH OF THE FELLOW RIVER,IN DONGPU DEPRESSION

黄河南地区众多的砂体类型和较强的成岩作用形成不同的储层特征,并使储层的油气储集性变化较大;砂岩的岩石结构和砂岩所经受的成岩作用不同程度地支配着储层的性质,从而控制了油气的聚集和分布。

Multiple types of sandbodies and their strong diagenesis in Yellow river south area resulted in different features of the reservoirs and a serious vari- ation in their features of oil and gas accumulation.Depositional and diage- netic processes in sandstones controlled reservoir features to a different de- gree,and thus the accumulation and occurence of oil and gas are controlled in turn.
