Seismic Data Processing Methods and Its Application in Loess Tableland Area of Ordos Basin
Qigang Zhou · Journal of Oil and Gas Technology · 2012
In the south of Ordos Basin,surface condition in loess tableland area was complicated,loess was thick,dry and loose,there existed serious problem of correction,data signal to noise ratio was low,it resulted in great difficulty for seismic data processing.A nonlinear tomographic inversion method of TOMODEL system was used to effectively solve the problem of static correction in loess tableland area.The encryption speed analysis was combined with surface consistent residual static correction technology,thus the quality of the profile was improved.The actual data processing shows that in the loess tableland area the method can be used to effectively improve the image quality.
