METHOD OF INTERPOLATING THE SPACE TRACE WITHOUT FOLDING IN THE DOMAIN F-K, FOR SEISMIC EXPLORATION

摘要

The object of the invention is to provide a method for the economic removal of the folding of spatial folding data in three dimensions. This method is computer assisted to provide a set of output data freed from the folding of the data. , xL, yL), from an input data set with spatial folding of seismic signals, a (t, x, y), where L is an interpolator. The known set of data is filled with zeros by L, which is masked from zero. The data set filled with zeros is divided by a zero-filled data set, masked with zeros, to output an HL interpolation operator. The traces of L-1 zero are nested between the known traces of the data set a (t, x, y) to deliver a set of inserted data of zero CL (t, xL, yl) whose transformation is CL ( m, kxL, kyL). The product of (HL) with (CL) is (DL) is transformed inversely to deliver the set of data freed from folding dL (t, xL, yL). / P
