Hierarchy analysis and model fitting techniques are used to describe the point bar configuration of the meandering river deposits in the Neogene Guangtao Formation in the middle unit of Block 7 in the Gudong oilfield.According to the lithologic and electrical properties of sedimentary microfacies in the meandering river deposits and in combination with the modes of deposition

we divide the sedimentary microfacies and identify two point bars in the study area.With production performance and test data

quantitative models of point bar configuration unit are built

which includes the orientation

dip

space and horizontal width of a single lateral-accretion sandbody.Under the guidance of the models and constraints of well data

we analyze in detail the internal configuration of the point pars and build 3D models for point bar configurations of meandering river deposits.Furthermore

we analyze the remaining oil distribution and presents specific measures to tap the production potential.
