【摘要】 对传统的VSP-CDP方法进行了改进,提出了XSP-CDP井间地震叠加成像方法,即利用逐段迭代射线追踪法代替常规射线追踪方法进行归位成像。利用该方法对合成井间地震数据和野外实际井间地震资料进行了叠加成像,结果表明,本文方法运算速度较快,成像剖面质量较高,包含了丰富的地层信息,能够满足实际处理要求。更多还原

【Abstract】 By improving the traditional method of VSP-CDP stack,a method of XSP-CDP crosswell seismic stack imaging was proposed,in which the ray tracing of piecewise iteration,instead of the conventional ray tracing,was used to get images.This XSP-CDP imaging method has been used to do stack imaging between some synthetic and real crosswell seismic data,indicating that it can satisfy the actual requirements of seismic processing,due to its rapid calculation,high quality of imaging sections and ability to provide rich stratigraphic information.更多还原
