Based on core, rock slice, cast andmercury 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 lowporosity and lowpermeability. The reservoir space ofmagmatic rock reservoir is mainly controlled by lithology, tectonic disruption and atmospheric fresh water leaching.
