东濮凹陷低阻油层的形成机制及其勘探

Mechanism of Forming Low Resistivity Reservoirs and the Exploration in Dongpu Depression

通过分析低阻油层形成的主要因素及其形成机理,指出东濮凹陷低阻油层形成主要受控于形成油气藏的内外因素,从含水饱和度意义上划分为高束缚水饱和度低阻油层和含可动水的低含油饱和度低阻油层2种类型,并针对不同类型低阻油层的勘探策略和研究方法进行了分析。

By analyzing the major causes of low resistivity reservoir formation and its forming mechanism,it is pointed out that the formation of low resistivity reservoirs in Dongpu Depression is mainly controlled by both internal and external factors of reservoir formation.The reservoirs can be divided into high irreducible water saturation and low resistivity reservoir,saturation and low resistivity reservoir with movable water from the aspects of water saturation,and the strategy of exploration study methods are analyzed from different types of low resistivity reservoirs.
