Abstract：There are thirty years of history for Chinese offshore oil-gas exploration and some structural oil-gas reservoirs have been successively found.Because difficulty of exploration became more and more,how to find lithologic reservoir and lithologic-structural compound reservoir is our important studying task,among which how to use seismic information to distinguish (or predict) reservoir is our first research task.In recent years,we developed a large amount of research jobs in this domain and achieved many geologic results,The research showed that "bright point" technique,AVO,trace integration technique and 4-G seismic technology are effective techniques for distinguishing gas reservoir in Yinge Sea Basin.Gomprehensive utilization of the above-mentioned technology,we predicted successively large-scale or middle-scale gas field with considerable reserve:Yacheng 13-1,Dongfang 1一1,Ledong 22-1 and Ledong 15-1,etc.,which were proved by drilling,achieving significant both economic and social benefits.
