Abstract

Fault block developed well in Dagang Oilfield, so the geology is complex. The research on the petrofacies and paleogeography in fault block region is significant for finding non-structural reservoir. A great number of lithostratigraphy traps formed in Qikou Sag due to the special petrofacies and paleogeography. Based on the petrofacies and paleogeography conditions, combined with the factors for lithologic trap forming, the probability of obtaining high productivitywell in Binhai slope region in Qikou Sag is discussed.

Key words： Maokou Formmion; third-order sequence; sedimentary facies; depositional model; southeastern Sichuan
