Seismic Facies Study by Using Seismic Data of High Resolu tion

Seismic facies in the Wuyang depression was studied in respect of seismic sequence division,analysis of seismic facies types and features by using high-resolution seismic data.There developed mainly alluvial fan,fan delta and delta sedimentary facies in the depression.They were divid-ed into9types.The plane distribution features of each seismic facies are presented in this paper.
