Abstract
With real seismic data, this paper makes the model restrained by top and bottom. The tops are positions which are interpreted along lineups skipping phases in an apparent cycle and following lineups strictly. The bottom is a position which is interpreted along lineups automatically. Through comparing the slices in different models, the authors studied the effect of time-crossing on strata slice. The findings show that slight time-crossing has a certain effect on strata slice, but will not affect the whole state of lithofacies distribution. Instantaneous amplitude is not related to instantaneous phase. When time-crossing is higher than 3/4 of a apparent cycle, the whole state of lithofacies distribution in strata slice with instantaneous amplitude will be affected. If the extent of time-crossing is greater, the effect will be more obvious. The effect of time-crossing on strata slice is connected with the size of the time window and the characteristics of seismic attributes. The smaller the time window is, the more obvious the effect is. A comparison with instantaneous attributes shows that, when the seismic attribute in strata slice is a statistic one, time-crossing will have a slight effect on strata slice.关键词
