| 摘 要： | 综合应用测井资料和铸体薄片、扫描电镜、X—衍射、粒度、压汞等分析化验资料，对西峰油田庄40井区块长6储层的特低渗透成因和主控因素进行了分析。结果表明:该区块长6储层特低渗透成因主要受沉积作用和成岩作用的共同影响，主要表现为沉积微相对储层物性的影响较大，扇中和扇根明显好于扇端，而且粒度偏细也是造成特低渗的主要因素之一，但是成分成熟度对该区长6储层特低渗透成因影响不明显；成岩压实作用和胶结作用使得储层孔隙、渗透性减小、变差，而溶蚀作用和成岩缝的产生又为储层中油气的赋存和渗流运移提供了有利条件。

| Abstract: | The origin of extra low-permeability and controlling factors of Chang 6 reservoir in Zhuang 40 area of Xifeng oil field are studied synthetically through using the log information, testing and analytical information such as casting section, scanning electron microscope, X-diffraction, grain size analysis and mercury penetration, et al. The results show that sedimentation and diagenesis have impacted on the origins of extra low-permeability together, it is displayed that microfacies influenced properties greater, the properties in the medium of alluvial fan are better than that in the fringe. Meanwhile, grade in another factor caused the origin of extra low permeability, however, the component maturity have not showed obvious influence on the origin of extra low permeability, compaction and cementation decreased the porosity and permeability, denudation and diagenetic microfracture provided favorable conditions for the existence and movement of oil and gas. |
