【摘要】：對(duì)地震數(shù)據(jù)進(jìn)行預(yù)處理,增強(qiáng)同相軸的連續(xù)性,然后引入支持向量機(jī)技術(shù)對(duì)地震剖面上的點(diǎn)進(jìn)行分類(lèi)處理,同時(shí)以地震振幅、瞬時(shí)相位、層位傾角、信息素濃度等信息作為蟻群層位追蹤的評(píng)價(jià)函數(shù),提出改進(jìn)蟻群搜索的地震層位對(duì)比和自動(dòng)追蹤算法。在此基礎(chǔ)上,將時(shí)深域沉積旋回韻律體對(duì)比追蹤結(jié)果轉(zhuǎn)換到Wheeler域,實(shí)現(xiàn)時(shí)間域和Wheeler域的同步解釋,從而有效揭示沉積組合的空間關(guān)系,突出缺失和疊加模式,使在年代地層域中提取時(shí)間切片成為可能,對(duì)沉積、侵蝕和沉積時(shí)間有更深刻的理解。實(shí)際地震資料的應(yīng)用結(jié)果驗(yàn)證了方法的有效性。
[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.
