- By using core, slice, Scanning Electron Microscope, high pressure mercury injection and physical property data, this paper analyzes the lithology, pore structure, fracture and physical property characteristics, classifies the reservoir types of Chang 6 oil-bearing formation in Yuekou area. The results shows that fine arkose is the main rock type, about 74% of the reservoir space is residual inter-granular and dissolved pores, high angle inclined or vertical fractures constitute the main core factures, vertical and parallel micro-fractures are discovered under microscope which have the same direction as big fractures, the porosity mainly ranges from 6% to 10%,, the permeability is mostly less than 1×10-3 m2, and belongs to tight reservoir. With the integration of multiple factors, Chang 6 reservoir types are divided into good, relatively good, relatively poor and poor.
