Abstract:It is very difficult to identify low-grade faults due to small fault displacements and short extended length,which affects the hydrocarbon exploration and production in complex fault-block zones for the late stage of oilfield development.We propose an approach to identify low-grade faults with above 3m fault displacement in the fault block Yong 3,Dongying Sag with the joint use of logging and seismic data.This is a high-density well pattern zone.First,the similarity of same-microfacies logging curves between neighboring wells is used to obtain the development index of low-grade faults,and low-grade fault breakpoints encountered by drilling are quantitatively identified.Then drilling information is used to guide the seismic data interpretation after an accurate well-seismic calibration.Plane distribution characteristics of low-grade faults are depicted based on ant traces under the guide of these fault breakpoints.The approach takes advantages of high vertical resolution in logging data and seismic lateral information.The low-grade fault interpretation is realized from a point-line-surface (well-seismic line-horizon attributes) aspect.The low-grade fault identification in the study area with the proposed approach is verified by the dynamic production of the oilfield,which provides a very helpful reference for the oilfield future development.
