利用储层砂岩薄片鉴定与电镜扫描、压汞测定等方法,对青平川长2储层岩石学特征、储层物性特征、储集特征进行了系统的研究。结果表明:青平川长2储层属于中低孔、中低渗储层;储层岩性以长石砂岩为主;研究区储层孔隙空间主要有粒间孔隙、粒内溶蚀孔隙、晶间微孔,长石、石英等微裂隙。通过对该区储层特征的研究,可为下一步勘探开发提供地质依据。 Based on the identification of sapphire reservoirs, scanning electron microscopy and mercury intrusion porosimetry, the petrological characteristics, reservoir physical properties and reservoir characteristics of Changping2 reservoir are studied systematically. The results show that the reservoirs of Qingpingchuan Chang 2 belonged to middle-low porosity and medium-low permeability reservoirs, and the lithology of reservoirs mainly consisted of feldspar sandstones. The pore spaces of the reservoirs mainly included intergranular pores, intragranular dissolved pores, Microporous, feldspar, quartz and other micro-cracks. Through the study of reservoir characteristics in this area, it can provide the geological basis for the next exploration and development.
