The curve shape and characteristics of self-potential and gamma-ray logging curves have close relations with sedimentary facies and reservoir rocks. They are very sensitive to the grain grade, sorting and shale content of sedimentary sequences at different sedimentary environment caused by different hydrodynamics condition. Using the evaluation of reductive amplitude difference of self-potential and gamma-ray logging, the penetrative sandstone layers were identified, the favorable sandbody sedimentary micro-facies belts were divided, the low and tight penetrative sandstone layers were identified, the channel flank sedimentary micro-facies belts and the oil-water layers were divided. The lower limitation standard of reservoir was established to divide reservoir through the reservoir application of self-potential and gamma-ray in Block Wen 15, having obvious abnormal indication in different sedimentary micro-facies belts.
