Seismic Facies Classification Based on Logging Data and Seismic Attribute

Seismic facies have the main features of specific sedimentary facies or geologic bodies that reflect from the seismic section,which is the link between sediment and seism.Making use of seismic calibrating result and acoustic travel time statistics of the well in different facies belt,we could preliminarily get the distribution map of seismic facies from the regular seismic section and instantaneous phase section.According to the features like the outside structure of seismic reflection layer,frequency,amplitude and consistence,we could establish three sedimentary facies that are corresponding to the seismic facies models.On the basis of this,we analyze the slice of seismic attribution from the top boundary of target layer,single out the seismic attribution which can distinguish the facies belt and finally determine the distribution area of seismic facies,all of which will provide a technical support for reservoir prediction and reef discovery in the future.
