基于共反射点叠加的观测参数选择
THE SELECTION OF THE RECEPTION ARRANGEMENT PARAMETERS BASED ON COMMON REFLECTION POINT STACKING
【摘要】 在地震勘探数据处理中,通常采用的共中心点(CMP)叠加技术对于复杂的地质构造难以取得好的效果。若通过从道间距、覆盖次数等观测参数与目标层地层倾角、共反射点离散度的关系出发,并结合模型正演,对复杂构造地层的观测参数选取进行优化,使之能对目标层尤其是逆断层下降盘的阴影层段进行较充分的"照明",即可得到共反射点叠加剖面,这对共反射点叠加是一项有益的研究。
【Abstract】 As the common mid-point (CMP) stacking is hard to get a good effect in the complicated geological structure in seismic data processing, the common reflection point(CRP) stacking is used. Analyzing the relation of the steep dip, dispersion of common reflection point and parameters of reception arrangement such as trace interval ,fold number etc., the parameters of reception arrangement are optimized with the forward modeling. Finally the CRP stacking sections are achieved, which is potential for the research of common reflection point stacking.
