At any stacking bin coordinate, the stacking fold inside the bin varies with depth. Referring to figure 2, when a stacking bin is centered about a deep reflection point B, the stacking fold is a maximum at depth B because the largest number of source and receiver pairs can be utilized to produce individual reflection field traces inside the bin. The number of source-receiver pairs that can contribute to the image at B is typically confined to those source and receiver stations that are offset horizontally from B a distance that is no larger than depth Z2 to reflection point B." http://www.aapg.org/explorer/2010/11nov/geocorner1110.cfm -------------------------------------------------- Note added at 2 hrs (2011-10-13 19:21:48 GMT) -------------------------------------------------- 104 - nombre de signaux réfléchis? -------------------------------------------------- Note added at 2 hrs (2011-10-13 19:22:41 GMT) -------------------------------------------------- je vois plus loin dans votre doc : "Distinct specifications of the apertures: - number of source/receiver stations in each aperture is about 100;" |
