Volcanic rock reservoirs in China have great oil-generating potential��especially in the Songliao Basin�� where the volcanic rocks widely existed�� Thus��how to recognize the volcanic rock reservoirs effectively is significant�� The seismic attribution is an effective analysis tool of reservoir characteristics��which is the parameter to study the spatial distribution of volcanic rocks�� Frequency��seismic dip and curvature are sensitive characteristics to identify the volcanic rocks by seismic data�� The authors calculate the local frequency in the seismic profile to circle the area of low frequency using the method of local seismic attributes��and then calculate the curvature of the same profile to circle the area of high curvature value in curvature data volume�� Overlaying the two areas in seismic profile can recognize the possible distribution area of volcanic rocks and provide guidance to further recognition of volcanic reservoirs��
