Abstract: Reservoirs of the beach-bar sandstone and turbidite in the upper Es4 is widely developed in the Wangjiagang area. During the sedimentary period of the upper Es4, this area developed a multi-style sedimentary system, such as beach-bar sandstone and turbidite that were controlled by palaeogeomorphology, the overlapping relation between different types lithologic bodies are complex, the fact brings much difficulty to predict reservoir and impact the exploration and development of oil-gas in the area. A seismic reservoir inversion technique is applied to. According to the geological characteristics, the reconstruction of acoustic wave curve, and the seismic inverse of inversion model, through the verification of error analysis, a good inversion result and finish horizontal distribution of every sand group in the upper Es4 is obtained.
