地震属性技术的研究和应用

The application of the seismic attributes

地震属性的研究大致从上个世纪60年代开始,经历了几个阶段的发展后得到了广泛的应用.由于地震属性的解释可获得许多有关地层、断层、裂缝、岩性和相的变化的重要特征信息,我们结合地震属性特征参数的意义,从实际应用出发,把地震属性分为了振幅、频(能)谱、相位、复地震道、层序、相关六大类,并根据在地层、断裂、岩性等方面的实际应用进行了详细描述,讨论了属性分析技术原理中应注意的几个环节.最后通过对断裂、河道、火成岩、古潜山等几个实例的详细描述,证明了相干、阻抗、振幅等地震属性的应用效果,说明了地震属性在实际应用中的作用.

The study of seismic attributes started in 60s , it applied widely after several developed steps. From interpreting seismic attributes ,we can get many important information about faults, strata, fractures, lithology and seismic phase. Combining with the signification of particular parameters of seismic attribute, We separated the seismic attribute in six types, such as amplitude, frequency spectrum, phase, seismic traces, stratum sequence, correlation. We detailedly described those according to the use of detecting stratum, rupture, lithology. We also discussed several questions which lie in technique and theory of property analysis. At last , we described seismic attribute＇s （coherence, impedance, amplitude） applied effect in detail, According to several samples which used in rupture, riverway, lithology and buried hill, it proved that seismic attributes are really useful on stream.
