In recent years, the difficulty and risk have increased in exploration for the conventional petroleum. With the continuous discovery of the volcanic reservoirs, volcanic-related rock reservoirs have become a new field of hydrocarbon exploration, and have greatly attracted the attention of the petroleum geologists. Former researches mostly focused on the seismic character identification of extrusive igneous rock and extrusive igneous rock-related reservoirs, therefore the study of seismic character identification of intrusive igneous rock and intrusive igneous rock-related reservoirs has an important theoretical and practical meaning in hydrocarbon exploration. Through the comprehensive research of the typical igneous seismic profiles in Qiongdongnan basin, the stocks, laccoliths, sills and dikes were identified from other seismic characters, and their identification characters were also summarized. Finally by the analysis of their implications for hydrocarbon systems, eight kinds of intrusive igneous rock-related traps were proposed.
