| 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. |
