| 摘 要： | 通过对延8储层铸体薄片、扫描电镜、孔渗测定、压汞资料等分析,延8储层具有以下特征:研究区北边富长石、南边富石英,具有不同的物源;砂岩粒度以中粒为主,细粒和粗粒次之;主要的储集空间为粒间孔和粒内溶孔;由于大量的长石、岩屑被溶,孔隙度、渗透率不呈正态分布,均偏大,溶蚀作用形成的大量微孔造成高束缚水饱和度,产纯油或含水率极低;砂体厚度、岩石相和成岩作用共同控制着储集层的物性。结果表明,位于河道中部弱胶结的中砂岩具有良好的储集性能。

| Abstract: | Yan-8 Formation is an important explored layer in Mahuangshang area of western Ordos Basin.Based on cast thin section,scanning electron microscope,porosity and permeability determination and mercury penetration,characteristic of Yan-8 formation was discussed.It includes that plagioclase-rich in north and Quartz-rich in south have different provenance;loam-grained is the main compost in sand rock,followed by fine-grained and coarse-grained;the main reservoir was intergranular pores and intragranular dissolve... |
