Taking Ziyin Oilfield in Baise area of Guangxi Province as an example, the seismic attribute analysis technology and its application to prediction of reservoirs in the oilfield were introduced.

Diagenesis of Chang2 reservoir of Upper Triassic Series in Zichang oilfield and the factors of influencing the physical property of the reservoir;

By the research on the pore texture of rock, the relationship between porosity and permeability and the space distribution of reservoir in Chang 6 reservoir group of Zichang oilfield in Ordos Basin, it is considered that much higher heterogeneity exists at the innerbed, the interbed and the plane.

Zichang oilfield is located in the eastern slope of Ordos basin.

Well logging evaluation of the algal limestone reservoirs with middle-porosity and low-permeability in Youquanzi Oilfield of Qaidam Basin

Formation lithology in the Yousashan group is complex and the formation is finely-laminated in Youquanzi oilfield,which belongs to medium and low permeability reservoir.
