Super heavy oil reservoir with top water and edge water in Liaohe Oilfield is characterized by gentle structure, coarse rock particles, good physical properties, weak diagenesis, poor heterogeneity, no oil-water interface. The genesis of this special reservoir is discussed. The result shows that biodegradation is material basis, hydrodynamic force and water washing make the buoyancy affect crude oil movement little, and the “asphalt shell” formed by oxidation prevents the formation water infiltration, which is favorable for reservoir preservation.
