| 英文摘要 | The multi-trace geometry repeatability in the time-lapse seismic method was proposed recently. When it is applied to every bin successively, single-value repeatability of each bin is given, forming two-dimensional distribution of repeatability corresponding to stacked image traces. This is of significance on the evaluation of geometry repeatability for time-lapse seismic acquisition, processing and interpretation, in which the multi-trace repeatability should be addressed due to multi-fold of coverage. Previous research focused on the relationship between repeatability of a multi-trace set and its single-traces, and put forward its measurement of repeatability and theoretical basis. In this theory, the repeatability for multi-trace geometry relies on linear relationship between seismic image repeatability and geometry repeatability of single-traces, which is relatively precise only when single-trace repeatability is confined to limited range beginning with zero. In order to resolve this problem, we establish X-mode fitting for relationship between single-trace seismic image repeatability and single-trace geometry repeatability and put forward the collapse of single-trace geometry repeatability bigger than the X-node value so that the multi-trace geometry repeatability measurement reached by previous research is logically valid within full range of single-trace geometry repeatability. In this X-mode fitting, there are two straight lines with linear fitting : one is of zero intercept and the other is horizontal. X node is the point of intersection (D-x, d(x)) of two fitted lines. The final fitting function is composed of fitted linear function with zero intercept (0 <= d<(x)) and constant (D=D-x) function (d>d(x)). The study on real data shows some new features revealed by the analysis method and shows application value. The combination of extrapolation point, X node and its difference constructs a functional structure of the data via the comprehensive measurement method. This research is based on the essence of the previous research and an important development to it. The method we propose could be a tool for repeatability evaluation and can make time-lapse seismic data more useful. |
