Abstract:The Member 3 in Permian Wuerhe Formation in Zhongguai uplift, Junggar Basin is characterized by thin reservoir and lateral rapid variation. It is difficult to distinguish this kind of reservoirs with only seismic attributes or inversion. In order to accurately predict reservoirs in the area, we propose an approach based on tools provided by GeoEast. First we extract a variety of seismic attributes. Then we choose some seismic attributes which are related to sand body thickness. Finally with BP neural network we predict quantitatively the thin sand body distribution. It is found that the Member 3 in Permian Wuerhe Formation are grooved sand bodies. Our prediction matches very well with three drilled wells. The difference of sand body thickness between the prediction and the drilling information is not more than 1 meter.
