| 摘要: |
| 根据录井、岩石薄片、铸体薄片、压汞、物性分析等资料,结合沉积相,对古近纪-新近纪储层特征、成岩作用、孔隙演化等进行研究。结果表明:四棵树凹陷古近系-新近储层为中-细砂岩,储集空间以原生孔隙为主。其成岩阶段多处于早成岩B亚期,局部地区处于中成岩A亚期。通过分析,研究区古近系-新近系储层为中孔中渗储层,储集性能较好。 |

| Abstract: |
| The physical properties, diagenesis and porosity evolution of the Palaeogene-Neogene hydrocarbon reservoirs in the Sikeshu depression, Junggar Basin, Xinjiang are discussed on the basis of well logs, thin section examination and mercury-injection curves. The Palaeogene-Neogene hydrocarbon reservoirs in the Sikeshu depression are characterized by medium-to fine-grained sandstones, abundant primary porosity, and B substage of the early diagenesis and the A substage in local places. These hydrocarbon reservoirs belong to the moderate mesoporosity and mesopermeability reservoirs, and thus have good reservoir potential. |
