泌阳凹陷新庄油田油藏形成条件分析

An Analysis of Reservoir Forming Conditions in Xinzhuang Oilfield of Biyang Depression

叠瓦状油藏是新庄油田油层分布的普遍规律 ,从圈闭和盖层的有效性探讨了该类油藏的形成条件 ,认为主控断层对油层的封闭具有广泛性和相对性 ,断层封闭的广泛性导致了断层下盘高部位大多数储层都是油层 ,断层封闭的相对性是造成油层含油高度小的主要原因 ,盖层的厚度与油藏的含油高度具有正比关系。

Imbricated reservoir is the main reservoir type in Xinzhuang oilfield. The forming conditions of reservoirs are discussed in respects of the effectiveness of traps and seals. It is concluded that the main faults are extensive but relative seals of oil zones, thus most of the reservoirs in the high side of the footwalls are oil- bearing, oil columns, however, are low. The thickness of seals is proportionate to the height of oil column.
