摘要

///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.
