| 摘 要： | 彭滩-杨井地区长2主力层砂岩岩石学、成岩作用、孔隙类型研究表明：该区长2储层岩石类型以长石砂岩和岩屑长石砂岩为主，成分和结构成熟度均较低，主要经历的成岩作用有压实作用、胶结作用、交代作用和溶解作用。根据砂岩成岩作用特征，结合其埋藏深度、岩石古地温、有机质成熟度等分析资料及岩石结构、孔隙类型特征，长2主力层主要处于晚成岩A期成岩阶段。 |
| 关 键 词： | 鄂尔多斯盆地 长2储集层 成岩作用 成岩阶段 |

| Abstract: | The examination of petrology, diagenesis, porosity type and evolution indicates that the Chang-2 reservoirs composed of feldspar sandstone and lithic feldspar sandstone with low compositional and textural maturity have undergone several stages of diagenesis including compaction, cementation, replacement and dissolution. The Chang-2 reservoirs in the Pengtan-Yangjing region, Ordos Basin are now in Stage A of the late diagenesis judged from diagenetic characteristics, burial depth, palaeo-geotemperatures and organic matter maturity. |
| Keywords: | Ordos Basin Chang-2 reservoirs diagenesis diagenetic stage |
