| 摘 要： | 通过突变理论的尖点突变模型及分析,将地震信号转化为尖点突变的标准形式.在时间域、频域计算突跳势、突跳时间等突跳参数,分析突跳参数异常,较好的反映了煤层的不连续性;比较相干、突跳理论两种技术在反映煤层不连续性上的效果,分析了各种技术的优缺点.尝试将相干属性和突跳参数属性进行融合,得到新的属性切片,很好的反映了煤层断层和裂...

| Abstract: | The cusp model of catastrophe theory and its expression are mentioned in this paper.The seismic record is transformed into the normal form of cusp catastrophe.Catastrophic potential,catastrophic time and so on are calculated in time domain and in frequency domain.Analysis of catastrophic anomalies can better reflect the dis-continuity of coal seam.Comparing the effect of the theories of coherence and catastrophe in reflecting coal seam discontinuity,advantages and disadvantages of these two techniques were ... |
