该文根据大量的岩心岩石薄片、铸体薄片、压汞等资料,对东营凹陷太古界岩浆岩储层的岩石类型、储集空间类型、物性特征等进行了研究。结果表明：太古界岩浆岩储层主要以脆性的花岗岩类、闪长岩类和脉岩类为主要储集岩;储集空间以裂缝为主,其次为溶孔和溶洞,孔隙度和渗透率均较低,总体属于低孔、低渗的孔隙-裂缝型储层;岩浆岩储层的储集空间主要受岩性、构造破裂作用和大气淡水淋滤等因素的控制。

Based on core,rock slice,cast and mercury penetration data,the rock types,reservoir space types and reservoir properties of Archean magmatic rock reservoir in Dongying Sag are studied.It is considered that Archean magmatic rock reservoirs are mainly composed of brittle granide,dioritoid and dike rock,the reservoir spaces are mainly fractures,followed by dissolved pores and caverns,and the porosity and permeability both are low.So it belongs to pore-fractured reservoir with low porosity and low permeability.The reservoir space of magmatic rock reservoir is mainly controlled by lithology,tectonic disruption and atmospheric fresh water leaching.
