The commonly used method at present is to adopt the repeated stack interval of the data from the two sources to calculate the matching operator and then to perform the matched filtering
目前運用較廣泛的方法是,利用2種震源資料的重復疊加段求取匹配運算元,然後進行匹配濾波,但該方法要求重復疊加段有可靠的波組特徵和較高的信噪比。 -
So a new method, the cascade matched filtering processing technique characterized by pre - stack multi points, is proposed, which uses iteration before stack and utilizes stack to improve the stability of the matching operator to realize the consistency of the two kinds of source record
該技術在疊前通過逐步逼近法,並利用疊加手段提高匹配運算元的穩定性,實現提高2種震源記錄一致性的目的。 -
A hybrid migration method, named " fourier finite - difference migration ", is a post - stack depth migration scheme. the downward extrapolation operator is split into three operators : one operator is a phase - shift operator for a chosen constant background velocity, another operator is the well - known first - order correction term, and the third operator is a finite - difference operator for the varying of the velocity function. phase - shift downward extrapolation and finite - difference downward extrapolation preserves the advantage of phase - shift method and finite - difference method
傅立葉有限差分(簡稱ffd )偏移演算法是一種疊后深度偏移演算法,其向下延拓運算元是一種混合運算元,包括三項:一項是處理常速的相移運算元,一項是一階相移修正運算元,最後一項是類似45度方程的有限差分運算元,用來處理劇烈橫向變速。
