Application of FMI in Sedimentary Facies Analysis in the Northern of Dongying Depression

The data of micro-resistivity imaging (FMI) log from Yanjia Oil and Gas Field in the northern of Dongying Depression were used for the analysis and summary of identification models including lithology,depositional structure,and sedimentary rhythm reflected by FMI image and color.Hence,the sedimentation cycle was identified by integral use of core,standard logging and geological data.By extracting the features of sedimentary subfacies and micro-facies of glutenite reservoir,the identification models of sedimentary subfacies are summarized by FMI images,which provides a base for the further study of sandy conglomerate sedimentary facies.
