Effected by provenance from the depression northeast and the north, sandstones shaped as semicircle,are distributed in the depression northeast ,and then mudstone and silty argillite as its transition to the southwest. The sequence is classified into two types: alluvial fan-braided river sequence, which was formed by the strong tectonic movement in the lower Jurassic, lake-delta-meander river sequence that generated in the middle and upper Jurassic.

The technique of stratal slices can reveal the isochronism of sediment disperal patterns with high-resolution. And the sedimentary systems can be analyzed with lithologic log data. A shelf-edge deltaic system including fluvial plain, deltaic plain, deltaic-front, prodelta, and incised valleys was identified in Olmos formation of Gold River North Oilfield.

The deltas differ from typical deltaic model.Deltaic front subaqueous distributary channel sand bodies and deltaic plain distributary channel sand bodies are the skeleton sand bodies of meandering stream-shallow sea delta and braided streain-shallow lake delta respectively but not tranditional deltaic front river mouth sand bars.

The Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on. It had a beneficial geological condition to develope sublacustrine slump turbidite fans in Jishan, Jiangjiadian and Wawu.
