Application Seismic Inversion Technology Forecasting Reservoir

In order to solve the problem of reservoir fine description in the development process,curve reconstruction seismic inversion technology is put forward in the reservoir prediction job.According to the sandstone sensitive characteristics caused by different frequency range in the curve,develop the curve restruction technique on the basis of high-frequency recovery and low-frequency compensation and develop seismic inversion.Through the seismic inversion examples of the west districts of Nan8 show that:for more than 2m sandstone with high resolution and the small interlayer is too small,two sets of sandstone combine one sandstone to invert out.For less than 2m sandstone,only when the compartment is greater than 4m,it can be clearly identified.Seismic inversion can be very good at speculating the subsurface strata structure and the spatial distribution of the physical parameters.It can effectively improve the prediction precision of thin reservoir.
