Abstract
By taking Oilfield A of Huizhou Sag in the Pearl River Mouth Basin as an example,based on comprehensive analysis of core,logging,and laboratory data,the quality differences of Neogene shelf sand reservoirs were compared from macroscopic reservoir properties and microscopic pore structures,and the main controlling factors were analyzed to obtain the distribution pattern of high-quality reservoirs,which aims to provide guidance for the adjustment of oilfield development plans in the later stage.The results show that the diagenetic types and strengths of the target layers in Huizhou A Oilfield are similar,and the differ-ences in reservoir quality are mainly controlled by sedimentation,which directly controls the structural char-acteristics of the rocks,leading to differences in reservoir quality.Sedimentary evolution controls the differ-ences between layers,while sedimentary microfacies types control the differences within layers.Compared with the shelf sand sheet,the shelf sand ridge is a high-quality facies belt,which is an important target for adjusting oilfield development plan in the later stage.关键词
