Abstract: By analyzing the photos of scanning electron microscopy and thin section, intrusive mercury curve and materials of porosity and permeability, the reservoir characteristics of bioclast limestone member are discussed, which include petrologic feature, pore structure, reservoir space and reservoir properties of matter. Although the reservoir is deep buried, and primary pore was seriously destroyed by earlier compaction and cementation, the secondary pore developed very well by latter solution and dolomitization, especially dolomitization. Bioclast limestone member is quite capable of reserving oil and gas, and is classified as reservoir Ⅱ.
