The Format Criterion Of Doctoral Dissertation

With the deepening of the exploration degree,Sangtanghu basin in tight oil and gas exploration and development.This thesis is based on the Features of Permian carbonate formation in Malang sag permian dense oil reservoir as the research object,Using modern means like core observation,scanning electron microscopy analysis,And based on the study of the ancient people,combined with logging explain information research on the controlling factors of the permian carbonate formation in Malang sag permian dense oil reservoir to develop.research finding,the research area's lithology is primarily with the volcanic lava,pyroclastic rock,sinking pyroclastic rock,pyroclastic sedimentary rock.And development lake subfacies,braided river delta facies,volcanic facies and transition phase.Reservoir space are pore and fracture.Pore includes primary pore and secondary pore.The former includes primary stomata and primary microporous.The lattet are dissolved pores in grains,devitrification pore and organic pore.The research area development syngenetic diagenesis stage and early diagenesis A and B,middle diagenesis A.Analysis of main controlling factors of reservoir factors,lithofacies and crater control the reservoir's types of rocks,the different pore evolution because of the clastic content,decide reservoir's distribution.Diagenesis in the role is to take off the vitrified to get better reservoir physical property is the main role buried,factors such as mineral species directly affects the degree of vitrified process.
