Abstract
A discussion concerning the probability of variation in the amplitude correlation of the seismic wave extrema under the action of random interferences is presented. In the process of choosing a correlation version with the use of amplitude criteria, it was possible to pass from one phase to another in the result of variation in the amplitude relations between the signal extremes (under the action of interferences). This phenomenon was called here "the amplitude inversion. It was proved analytically that the probability of the amplitude inversion depended not only on the interference dispersion and the ratio of signal amplitudes, but also on the width of the band occupied by the energy spectrum of the interference. The probability of the inversions (especially of the near one) increased with the increase in the width of the interference spectrum. The concept of the "amplitude domination" (for the axes of the synchronous phases) is introduced, and used for the choice of the correlation variant in a set of permissible axes. -- Petroleum Abstracts.
