| 摘 要： | Y73井区位于鄂尔多斯盆地陕北斜坡带,该区主要产油层段为长6油层组,该段储层为湖泊三角洲沉积。长6油层组储层岩性以灰色细粒长石砂岩为主,其次为中-细粒、细-中粒、中粒及粉-细粒长石砂岩。微观孔吼组合以小孔-微细喉为主,宏观储层物性以低孔、特低渗为主。对储层物性影响最大的成岩作用为压实压溶作用、胶结作用和溶蚀作用。

| Abstract: | Y73 region is located in Shanbei Slope Belt, Ordos Basin. The Chang6 Formation is the main productive bed of this region, which is the reservoir of lacustrine delta deposits. The main reservoir lithology of Chang6 productive bed is the gray fine-grained feldspar sandstone. There are some secondary reservoir rock types, which are medium-fine, fine-medium, medium and silt-fine gained feldspar sandstone. For microscopic characteristic of reservoir, the main pore-throat type is low pore-minute-ness throat. The characteristic of physical properties is low porosity, extra-low permeability. The diagenesis, which has the greatest influence on reservoir pore, includes compaction, press solution, cementation and dissolution. |
