coherent stack 中文意思是什麼
coherent stack
解釋
凝聚層-
The improved algorithm has three steps : 1 ) estimating the statics ; 2 ) selecting the best coherent time window from the common - receiver - point stack profile for the coherent computation and calculating the statics ; 3 ) correcting the value of " statics " by the underground structures corresponding to the formation of the p waves
演算法可以分3步進行:估算靜校正量;在共接收點疊加剖面上選擇一個最優相千時窗進行相干運算,求取靜校正量;根據縱波對應層位的地下構造對相於結果進行校正。 -
Based on the similarity of common reflection point trace gathers in one coherent zone, crs stack can focus more energy on the vicinity of the reflector, and therefore can obtain a high signal - to - noise ratio zero offset section by stacking events with the same phase
共反射面疊加利用了鄰近多個共反射點道集的相似性,提高了資料的覆蓋次數,從而壓制了隨機噪聲,增強反射波同相軸的連續性,大幅提高了地震資料的信噪比。
