LOGGING DATA INTERPRETATION OF THE MUDDY RESERVOIR IN E₁f₂ OF SUBEI BASIN

Integrated interpretation is made for the data of logging, core observation, casting thin section examination, SEM analysis, triaxial shear test, bulk rock analysis and organic geochemistry. After pre-processing and standardization of logging data, some key parameters that affect the quality of the shale reservoir in E₁f₂ of the Subei Basin are extracted. Upon the basis, four basic models related to organic carbon, inorganic minerals, porosity and elastic parameters respectively are established. All the results after normalization are put into the physical model of bulk-volume rock for interpretation of target well. The research results prove that the above models are effective in the Subei Basin. Both favorable lithofacies and fracturing layers can be predicted via compressive interpretation of logging data. The research results may have some significance for reservoir evaluation and fracture prediction in the E₁f₂ of the Subei Basin.
