Incorporation with the lab and field experiments of gas condensate reservoirs leads to adjustment and tagging potential main achievements in this work are summarized as below: (1)The four—property(including lithology,permeability,porosity, saturation,resistivity)correlations are renewed,and the corresponding interFlretation models are established for different oil一bearing regions and hydrocarbon identification capability of oil一/gas—bearing layers is re—perforation productions are very encouraging· (2) By use of detailed reservoir characterizati
