Analysis of reservoir velocity modeling and domain conversion
摘要
Abstract
Full 3D space-variant grid velocity body is established by modeling method for time to depth conversion.Firstly,the quality of the wellbore and the seismic velocity spectrum data is strictly controlled.Then optimum volume trend constraint method is applied to wellbore velocity interpolation and extrapolation.It shows that the method can integrate wellbore velocity and seismic velocity efficiently,which contains abundant horizontal and vertical velocity information.It makes the change trend of velocity body,structural shape,wellbore and internal well velocity more reasonable.Finally,the structural model in depth domain can more precisely reflect the change trend of underground structure,and improve the correlation of data after domain conversion.关键词
