     Based on analysis of production performance data and gas chromatography fingerprint characteristics of oils from the second member of Shahejie Formation（Es2） in the Wangjiagang oilfietd, Dongying sag, connectivity among sand bodies was investigated and a mathematical probability model was established, and with this model, the sandstone carrier connectivity of the Shahe]ie Formation in the eastern part of the south slope of the Dongying sag was quantitatively described. The results showed that when the net-to- gross ratio is lower than 20%, sand bodies are isolated from each other; while the ratio is greater than 20%, the connectivity proba bility increases gradually with increase of the net-to-gross ratio; sand bodies are absolutely connected together when the net-to-gross ratio is greater than 80%. In particular, the connectivity probability of Es32 sandstone carriers is lower than 20% except for several areas such as the Wangjiagang oilfield, Bamianhe area and the southwest part of the study area. The connectivity of Es31 and Es2 sandstone carriers is very good, generally greater than 80%.
