Analysis of Sensitivity of Delta Facies Seismic Attributes Through Forward Modeling

Zhao Wang


The sand bodies of the underwater divergent channels in the delta subfacies in the delta are distributed in narrow strips, and the thin inter-layer characteristics are significant. This type of sand body has low control degree, and the prediction between wells mainly relies on seismic methods. It is affected by the quality of seismic data. The prediction accuracy is low. In this paper, taking the No.1 reservoir of Gaotaizi Oilfield Research Area as the research object, the forward model is used to describe the relationship between seismic attributes and channel sand body thickness.
