Analysis of Sedimentary Facies in Niuxintuo Reservoir of Niuxintuo Oilfield

Zhen He, Qing Tang

Abstract

Eighteen lithofacies in Niuxintuo reservoir of Niuxintuo oilfield are identified by core survey The characteristics of sedimentary facies in the area is analyzed in detail by combining well logging data The facies distribution and evolution are concluded Statistical analysis of the petrophysical data shows that the sandbodies from sandy and sandy rudaceous distributary channels of the fan delta front are favorable facies tracts in the area
