Abstract

Based on the analysis of core, logging and drilling, the sedimentary characteristics of braided channel in Serie Inferiere of Triassic in 438b block are analyzed. Combined with porosity, sand density, onrush coefficient, variation coefficient, permeability graded difference and frequency-interlayers, the entropy weight method is used to calculate the heterogeneous synthetic index in Serie Inferiere ofTriassic. The distribution map of reservoir heterogeneity is drawn based on sedimentary facies. This method can take fully advantages of entropy weight method, and it can accurately characterize the horizontal heterogeneity.

Key words： reservoir factors; sedimentary facies; Yanchang Formation; Hejiaji area
