Abstract
Summary
Identification of the interbedded thin bed has become a topical issues of the seismic exploration. The zero-crossing time slices technique is a new method which has the great advantage of depicting sand body. In this paper, we discuss the stability of this method by using different forward modeling. We test the influence of the prime frequency and phase of wavelet to the ZCTs intervals.Then we discuss the solution of the staggered finite-difference method to this model and inspect the feasibility of the ZCTs to real data. The result we got has proved that the method is generally applicable.
