Abstract：Based on secondary 3-D seismic data in Saihantala sag and combining with necessary new technique and tools,we implemented integral dissecting and evaluation of Saihantala sag,the studied area is divided into three levels: most favorable zone,potential zone for exploration and zone continue to actively explore by buildup of stratigraphic order framework and sedimentary analysis.Taking Sai-51.Sai-66 and Sai-84 as examples,the paper concretely expounded the process of objective evaluation and optimization,showing that the Saihantala sag is hopeful to become replacement zone of prospecting reserve in Erlian basin because of these three successful drilling holes.
