摘要
The dip logging data from the conglomeratic sand sub-section of Donghe sand member in Tazhong area of Tarim basin are processed in detail using geological structure diagram and core description information,and the parameters of long and short correlation processing for this area are presented.Based on the parameters,the eight dip logging response models for parallel bedding,low angle inclined bedding,middle angle inclined bedding,wave formed cross bedding,climbing-up bedding,wavy bedding,trough cross bedding,and massive bedding are established,by which the sedimentary structure interpretation of single well in the studied area is conducted.Combined with related sedimentary facies setting,such six sedimentary microfacies bedding combination models as foreshore beach,foreshore groove,foreshore dam,near shore beach,near shore groove and near shore dam are identified in order to fine classify the sedimentary microfacies.This method can make full use of the advantage of high-resolution of dip logging,increase the interpretation accuracy and obtain better results.
