The detailed seismic description of structure and reservoir is critical to successful exploration in Kendong shallow water area of Shengli oilfield. According to the characteristics of structures and reservoirs from Upper Tertiary formations, a set of detailed reservoir description techniques suitable for shallow water area are systematically summarized. Firstly, the fine structure description techniques were discussed, including fracture system description method and micro-structure mapping technique. Secondly, fine reservoir description techniques were discussed, including reservoir tracing based on horizontal slice, 3D volumetric displaying, logging constrained inversion, and multi-parameters analysis etc. Actual application shows that these description techniques can precisely predict beneficial zones. The horizontal well designed according to the prediction results enables the offshore oil production on land.
