Method of Reservoir Seismic Inversion and Its Application in the Q 3D Survey

There are many approaches in the terms of using seismic data to predict the reservoir in China and abroad.However,problems still exist such as low resolution of inversion result,multi-well extrapolation and mis-closure of inter-well.Aimed at the zone of interest in the Q 3D seismic survey,which is characterized by thin sand body as well as the quickly lateral alternation,three inversion methods of Strata software are put into use,including the 3-D wave impedance inversion,the well log parameter inversion,and multi-attribute gamma inversion.The method of multi-attribute gamma inversion has been proved to be the best way to solve the problems above.It offers high precision seismic inversion data for the exploration and development in the working area.
