Abstract：The heterogeneous distribution of oilfield reservoirs significantly impacts the production capacity in deep-water oilfields.This study focuses on the intra-layer,inter-layer,and planar heterogeneity of the lower section of the Zhujiang Formation in the Liuhua D deep-water oilfield in the South China Sea.Through in-depth research in combination with sedimentary environments and diagenetic processes,the internal heterogeneity distribution of the oilfield is clarified.The study suggests that the distribution of interlayer and interbeddings is an important factor influencing heterogeneity in the oilfield.There are six sets of interlayers and nine to ten sets of interbeddings in the reservoir.In addition,the oilfield is located near the ancient continental shelf break zone,where sedimentation changes from a delta front to a shallow-water carbonate platform.Under the background of marine transgression,sedimentary variations caused by the change in water dynamics are the main controlling factor affecting reservoir heterogeneity in the study area.
