摘要
According to the development effect of Neogene in Bohai Oilfiel in recent years,new hydrocarbon reservoirs are mainly the new-finding sand bodies at development stage.Sandstone and shale interbed is main sedimentary characteristics vertically and sandstone and shale develop alternately in laterally.That is caused by stream channel migration to form poor reservoir continuity.Identification and portraying of resolving fluvial facies reservoir are a key.Development practice has proved that single geophysical technology can not satisfy the prediction request of fluvial facies reservoir.This article puts forward that the quantitative prediction of reservoir,based on seismic-compound microfacies analysis and combined with logging constrained inversion,seismic attribute,formation slice,can be carried out under the conditions of high-accuracy sequence stratigraphic framework.
