【摘要】 山区大倾角地层地震资料处理的困难来源于动校正量、静校正量的非线性耦合,以及偏移量大造成的CMP道集围绕真实面元位置的发散。就几何地震而言,这三个因素是以非线性方式耦合在一起的。在讨论偏移、动校正、静校正耦合方式的基础上,利用空间坐标变换法结合某区实际资料,研究了如何用常规处理软件系统来处理山区大倾角地层地震资料的问题。这一实例对于促进复杂地区地震资料处理技术的发展应有一定价值。更多还原

【Abstract】 Difficulties of mountain area high-dipping strata seismic data processing are from nonlinear coupling of dynamic correction size,statics size,and divergence of CMP channel set around the actual position of binning from larger amount of migration as well.From geometric seismological point of view,these three factors are coupled together in a nonlinear pattern.On the basis of coupling pattern of migration,dynamic correction and statics,by the use of spatial coordinates transformation and combining of practical data from a certain area,the paper discusses how to use conventional processing software on mountain area high dipping strata seismic data.This example should be a promoter of seismic data processing technology in complex areas.更多还原
