Application of Elastic Wave Impedance Inversion Technique in BY Block

Prestack inversion is the major method of seismic reservoir prediction technology.Because of BY Block poststack inversion is difficult to accurately describe the reservoir,this thesis takes the pre-stack elastic impedance inversion technology to indicate elastic impedance difference is sensitive to the effective reservoir,the bigger elastic impedance difference is the effective reservoir,which are obtained from the intersection analysis of rock property and the rock property.On this basis,according to prestack gathers elastic impedance inversion,and calculating the far and wide elastic impedance defference of data volume is calculated,by means of logging calibration to extract the data of the far and wide elastic impedance difference data,the favorable reservoir is analyzed,the better effect is obtained.
