| 摘 要： | 依靠薄片鉴定压汞资料、薄片鉴定和测井资料、岩心观察等方法,对鄂尔多斯盆地华庆地区的长63储层特征,建立了储层分类标准,结果表明:华庆地区岩石类型主要是岩屑长石砂岩,长石溶孔、微孔为主要的储集空间,孔隙结构比较复杂,长63储集砂体在分类上属于低孔-特低孔、特低渗-超低渗储层。华庆地区长63储层根据储层分类评价的标准可以分为3类,以Ⅰ类、Ⅱ类为主。

| Abstract: | This article is based on previous research in thin section identification,including mercury intrusion data,physical properties analysis,core observation and log data.The characteristics of the Chang 63 reservoir in Huaqing area of the Ordos basin are systematically studied,and the standard of reservoir classification is established.The results show that the rock type of Chang 63 reservoir is mainly characterized by lithic feldspathic.The reservoir space is dominated by feldspar dissolving holes and micropores.Where pore structure is complex with strong heterogeneity,it belongs to reservoir with low porosity-extra low porosity,extra-low permeability and ultra-low permeability.According to the reservoir evaluation criteria,the reservoirs in the study area were divided into three categories,mainly in Type 1 and Type 2. |
