济阳坳陷桩西潜山内幕型储层特征及其成因

Characteristics and Genesis of Internal Type Reservoir of Zhuangxi Buriedhill,Jiyang Depression

桩西潜山具有较大的勘探潜力,以发育潜山内幕的裂缝型油藏为主。通过分析桩西潜山内幕储集层类型及特征,探讨了内幕型储层的成因机制,认为该内幕储层的形成主要与岩性、断裂构造、滑脱构造及其埋藏溶蚀的相互作用以及次级不整合面风化壳溶解有关。

Buried hill in Zhuangxi has great exploration potential,which is given priority to fractured reservoir of in⁃ternal buried hill.Through the analysis of types and characteristics of internal buried hill type reservoir in Zhuangxi,the formation mechanism of internal type reservoir is discussed.It is concluded that the formation of the internal type reservoir has relationship with lithology,fracture structure,detachment structure and its interaction with burial disso⁃lution,as well as dissolve of weathering crust of the secondary unconformity surface.
