摘要
鄂尔多斯盆地南部黄陵地区延长组长6、长8储层主要发育残余粒间孔、溶蚀粒间孔和溶蚀粒内孔等孔隙类型,多为小-微孔—微细喉型和中孔—细-微细喉型孔隙结构。通过储层物性与电性特征分析等途径认识储层性质。研究区长6储层属于特低孔、超低渗储层,长8储层属于超低孔、超低渗储层。长6、长8储层测井解释孔隙度、渗透率结果与岩心物性实测结果差别较大。
There are mainly residual intergranular pores and dissolution intragranular pores and dissolution intergranular pore types and so on,and pore structure mostly includes small-micro pore-microfine throat type and medium pore-micro-fine throat type of Chang6and Chang8Reservoir in Huangling area,the south of Ordos Basin.By the analysis of characteristics of physical property and electric property,reservoir properties have been understood in Chang6and Chang8Reservoir.Chang6Reservoir belongs to very low porosity and ultra-low permeability reservoir and Chang8Reservoir belongs to ultra-low porosity and ultra-low permeability reservoir in the study area.There is larger difference between the porosity and permeability from logging interpretation together and the porosity and permeability from the core analysis in Chang6and Chang8Reservoir.
