摘要
在尖点突变理论的基础上,建立了地震信号尖点突变模型并转化为尖点突变的标准形式,分别在时间域、频率域内提取突跳时间和突跳势参数。运用突变理论对实际地震资料进行断层检测表明:突跳参数曲线上异常的位置与断层的位置有关,为断层检测提供了一种新的途径。
On the base of catastrophic theory, a cusp catastrophic model was described.And the seismic signal was transformed into the normal form of cusp catastrophic.The parameters of catastrophe, such as time-domain catastrophic time, time-domain catastrophic potential, frequency-domain catastrophic time and frequency-domain catastrophic potential, are calculated in time and frequency domains.For the application of real seismic data interpretation, it is found that the position of abnormality of the catastrophic parameter curve or profile is related to the location of fault.Catastrophic theory can provide a new method for fault detection.
