Abstract

Abstract

Abundant beach-bar sandbodies with rich oil and gas resources are widely distributed in the upper part of the 4th member of the Paleogene in Jiangjiadian area of Huimin Sag. The beach-bar reservoirs are characterized by interbedded sandy and muddy deposits, thin sand layers, and drastic lateral facies variation. It made the seismic interpretation and reservoir prediction very difficult in practice. In this paper, we studied the beach bar sandstone and its relationship with paleotopography within a sequence stratigraphical framework by means of logging, well logging, seismic facies analysis and multiple attribute fusion technology. As the results, beach-bar sandstones were effectively identified that is helpful to oil and gas exploration in the sag.
