Title: Microfacies Research of Fan Delta Front of Qiketai Formation of Block Le3
Abstract: According to the rock core description,on the basis of the integrated analysis of rock core,electric characteristics,sedimentary structures,petrofabric and rock facies,the types and the characteristics of the sedimentary microfacies in Qiketai formation were studied.It indicated that Qiketai belongs to the fan delta facies,which can be further divided into two subfacies including the front delta and shore-shallow lake subfacies and four microfacies including underwater distributary channel,underwater distributary interbasin,underwater overflow deposit and delta front sheet sand microfacies.The distributary channel microfaces is the favorable reservoir,and delta front sheet sand is the secondary one.
