鄂尔多斯盆地富县地区延长组长6、长8低孔渗储层物性及其影响因素
Low-porosity and low-permeability hydrocarbon reservoirs and their controlling factors in the Chang-6 and Chang-8 members of the Yanchang Formation in the Fuxian region,Ordos Basin
摘要
Abstract
In the light of thin section examination,SEM,X-ray diffraction analysis and mercury injection analysis, the porosity and permeability and their controlling factors are explored for the hydrocarbon reservoirs in the Chang-6 and Chang-8 members of the Yanchang Formation in the Fuxian region,Ordos Basin. The hydrocarbon reservoirs in the Chang-6 and Chang-8 members of the Yanchang Formation consist dominantly of lithic feldspar sandstone and subordinately of feldspathic litharenite,which are moderately to well sorted,subangular to subrounded,and in contact cementation. The porosity types include residual intergranular pores,interstitial micropores,intergranular solution openings,intragranular solution openings and microfissures. Influenced by lithology and diagenesis,the hydrocarbon reservoirs in the Fuxian region are assigned to the low-porosity and low-permeability hydrocarbon reservoirs.关键词
