发布时间：2018-07-24 22:05
【摘要】：对地震数据进行预处理,增强同相轴的连续性,然后引入支持向量机技术对地震剖面上的点进行分类处理,同时以地震振幅、瞬时相位、层位倾角、信息素浓度等信息作为蚁群层位追踪的评价函数,提出改进蚁群搜索的地震层位对比和自动追踪算法。在此基础上,将时深域沉积旋回韵律体对比追踪结果转换到Wheeler域,实现时间域和Wheeler域的同步解释,从而有效揭示沉积组合的空间关系,突出缺失和叠加模式,使在年代地层域中提取时间切片成为可能,对沉积、侵蚀和沉积时间有更深刻的理解。实际地震资料的应用结果验证了方法的有效性。
[Abstract]:In order to preprocess the seismic data and enhance the continuity of the in-phase axis, support vector machine (SVM) is introduced to classify and process the points in the seismic section. At the same time, the seismic amplitude, instantaneous phase, horizon inclination angle are used to classify the seismic data. The information such as pheromone concentration is used as the evaluation function of ant colony horizon tracing. An improved seismic horizon comparison and automatic tracking algorithm for ant colony search is proposed. On this basis, the tracing results of prosody of time-depth sedimentary cycles are converted to Wheeler domain, and the synchronous interpretation of time domain and Wheeler domain is realized, which effectively reveals the spatial relationship of sedimentary assemblages and highlights the missing and superimposed patterns. It makes it possible to extract time slice in chronostratigraphic domain, and has a deeper understanding of deposition, erosion and deposition time. The validity of the method is verified by the application of the actual seismic data.
