Seismic facies analysis technique has been widely used in seismic data interpretation，the technology is faithful to seismic information, which overcomes some defects of seismic inversion technology, and is one of the important means to study the sedimentary facies and the target layer. Through the past quakes in eight femoral region check seismic data phase analysis and research, according to the actual area of exploration, on the seismic facies of the object analysis, favorable facies belt was predicted by subsequent exploration work , the useful suggestions were put forward to solve some practical problems in the exploration. By analyzing the seismic characteristics of sedimentary environment, it is important for guiding the exploration work in the future.
