Application of four property correlations of reservoir in Hu 154 well area

Accurate logging interpretation is the basis of reservoir fine description and research.According to the data collecting,arranging,correcting and analyzing of Hu 154 well area Chang 4+5 segment well logging,mud logging,rock core and testing data,the characteristics and relationship of Chang 4+5 segment lithology,physical properties and electrical features has been identified,the suitable porosity,permeability and oil saturation interpretation chart has been established.Combined with the oil testing data,the oil and water layer electrical features identified criteria and effective thickness limit has been determined.The porosity lower limit value is 6%,permeability lower limit value is 0.08×10-3 μm2,interval transit time lower limit value is 205 μs/m,effective thickness start value is 0.4 m,which provided a strong basis for Hu 154 well area Chang 4+5 segment further exploration,development and evaluation.
