摘要: 根据白云岩物性、压汞分析以及铸体薄片观察,详细论述了本区白云岩的岩石学、孔隙和物性特征,指出白云岩的主要储集空间为晶间孔、晶间溶孔和裂缝,细、粗晶白云岩物性好。依据白云岩物性和孔隙结构参数,本区白云岩属Ⅰ、Ⅱ类储层,并且是本区油气勘探重要的储集目的层。

Abstract: Based on the physical properties of dolomite, mercury in trusion analysis and the identification of cast thin section, the petrology, porosity and physicalproperties characteristics ofdolomite in the Shuanghu area, Qiangtang Basin study area have been discussed in detai.l Ithas been pointed that, themajor accumulated spaces of dolomite are intercrystal pores, intercrystal solution pore and fissure, and fine or coarse crystalline dolomite has good physicalproperties. According to the physicalproperties of dolomite and pore texture parameters, the dolomite reservoir in the study area has been classified intoⅠandⅡtypes, and it is the important objective in the exploring oil and gas.

Key words: Qiangtang Basin, dolomite, physical properties, pore texture, reservoir characteristics
