标准的叠前多次波消除技术,例如预测反褶积或拉冬变换,在遇到复杂构造时是失败的。 Delphi联合会提供了一种具有吸引力的2D方法,因为理论上该技术不依赖于地下构造,因此适合解决所有与地表有关的多次波,不论其复杂性如何。 Delphi技术有两个步骤:(1)计算全部有关的褶积项;(2)寻找使户P_0能量最小化的子波W。然而,这其中也存在着与有限的炮检距范围有关的问题:如果震源和检波器对应于最小炮检距,则其间没有用来模拟多次波的记录道。这一缺陷早已为人识别,且已公布了很多外推丢
Standard pre-stack multiple-elimination techniques, such as predicting deconvolution or dragons transformation, fail in complex configurations. The Delphi Confederation offers an attractive 2D approach, as the technology theoretically does not depend on subsurface structures and is therefore suitable for solving all surface-related multiples, regardless of their complexity. Delphi technology has two steps: (1) Calculate all related convolutions; (2) Find the wavelet W that minimizes the energy of P_0. However, there is also a problem associated with a limited offset range: if the source and detector correspond to the minimum offset, there are no tracks to simulate multiple waves. This flaw has long been human identification, and has been announced a lot of extrapolation
