摘要: 通过探讨地震同相轴和地层的关系,认为前人提出的地震同相轴是代表同一沉积序列年代地层的这个观点是不充分的,利用地层等时格架监督技术,通过理论模型和实际地震数据分析展示了地震同相轴与地震数据的频率之间有着很强的依赖性,一些同相轴不依赖于频率的变化而改变,但是有些同相轴却随着频率的变化而显示出不同的接触关系,同时证明了这些不依赖于频率变化的地震同相轴是反应地层关系的,从而防止了在地震解释过程中穿时现象的发生.这样可以得到更为客观的地震相,且越是高频地震数据的地震剖面,则会越较客观的反应地层,获得更接近于地质等时面的层位,而地震同相轴穿时的原因.一方面,对于给定的沉积序列没有足够的地震分辨率;另一方面,不规则的累加厚度或异常阻抗.

Abstract: Some views that seismic events represent the same sedimentary sequence by predecessors are not adequate. We use the isochronous sequence stratigraphy framework technical supervision to reveal the strong dependence between the seismic events and the frequency of seismic data by the theoretical model and the actual seismic data. Some events vary, which are not dependent on the frequency changes. However, some events show the different contacts along with the changes in frequency. Meanwhile, it proves that the seismic events which do not depend on frequency reflect strata connections. Thus, it avoids the traveling time occurrence in the course of the seismic interpretation, by which more objective seismic facies can be obtained. The more high the frequency of the seismic data is, the more objective the strata reflects. It is important in sequence stratigraphy research.
