Abstract:

The exploration practice in Sichuan Basin demonstrates that the reservoirs in Feixianguan Formation, lower Triassic are the porous bodies developed at the background of large area tight rocks, and related to beach facies, in general, there is a tendency of belt and sheetshaped distribution with strong heterogeneity partially. On the basis of comprehensive geologic research, the seismic prospecting technology of lower Triassic reservoir is summarized and improved, the available seismic data are fully employed, the traditional seismic facies identification technology used in oolitic reservoirs, Feixianguan Formation is further completed, reservoir prospecting research is conducted and a set of traditional seismic identification technology suitable for KaijiangLiangping Trough is explored.

Key words: seismic facies, reservoir prediction, Feixainguang Formation, Sichuan Basin
