| 摘 要： | 本文深入探讨了水、陆检波器的接收机制及波场动力学特征,认识到水层鸣震是由下行鬼波(虚反射)和上行微曲多次波组成。水检和陆检对于一次波、鬼波和微屈多次波具有不同的响应特征:对于一次波,双检的响应表现为同向;对于鬼波,双检的响应表现为反向;对于微曲多次波,双检的响应表现为同向。因此,本文通过水检和陆检同时采集的数据叠加去除鬼波;在此基础上,进一步求取海底反射系数,从而消除上行微屈多次波。本文方法在实际OBC资料处理中取得了良好应用效果。

| Abstract: | In this paper we discuss the receiving mechanism of hydrophone and geophone and dynamics characteristics of the wave field,and realize that the ringing of water layer is composed of down-going ghosts and up-going peg-legs.The response of primaries,ghosts and peg-legs between hydrophone and geophone are different.For primaries and peg-legs,their responses directions are same.But for ghosts,their responses directions are reverse.Therefore,ghosts can be removed through dual-sensor summation.Further bottom refl... |
