Abstract: According to the stratigraphic correlation and thickness maps by drilling and logging data from over 330 wells, the paper establishes stratigraphic framework to reveal its development, and shows the distribution of sandbody deposits with sandstone thickness and percentage content. The results show that during the sedimentary period of Upper Es₂ in Shengtuo Oilfield, there are three major provenances and one secondary provenance. The distribution of sandstone thickness in each sublayer reveals the distribution of internal provenances. The provenance in different sand formations or sublayers constantly migrate within a certain area, and the transportation directions of detrital materials in the basin also change correspondingly, which leads to the superimposition of sediments from provenances of different periods and sublayers. The synsedimentary faults also affect the provenance, and the strike controls the stratigraphic distribution and transport direction of detrital materials in the study area.
