高如曾:用地震动力学信息寻找微小断层的尝试,《石油地球物理勘探》,23(4)1988:497～503,512小断层,特别是落差微小的层间断层(<50m),与天然气聚集关系密切,已被大量的钻探实践所证明。本文利用小断层的正演模型和瞬时相位的变化,可查找落差小于50m 的断层。瞬时相位信息是一个与波能无关的量,它可提供断层两盘的层序结构变化的细节。利用此法对 D 构造上的小断层做了调查,发现了许多新断点。这些断点在获取的三维地震资料常规处理和解释中并未发现。
Gao Zeng: Attempts to find tiny faults with seismic kinetic information, “Petroleum Geophysical Prospecting”, 23 (4) 1988: 497-503,512 Small faults, especially small interlaminar faults (<50 m), gather with natural gas Closely related, has been proved by a large number of drilling practices. In this paper, we can find fault with a drop of less than 50m by using forward modeling of small faults and instantaneous phase changes. The instantaneous phase information is a wave-independent quantity that provides details of the changes in the sequence structure of the two plates in the fault. This method has been used to investigate D faults in small faults and many new breakpoints have been discovered. These breakpoints were not found in the conventional processing and interpretation of acquired 3D seismic data.
