转换波地震资料处理方法研究与应用
|
摘要
随着油气勘探开发的不断深入,转换波地震勘探已成为当前地震勘探研究的热点。通过对转换波处理当中的转换波静校正问题、方位旋转方法、共转换点道集抽取方法、转换波各向异性四参数速度分析方法以及叠前时间偏移成像等技术问题进行研究,并形成一套转换波地震资料处理流程。将上述方法与技术应用于苏里格地区实际地震资料,取得良好的应用效果。
With development of oil exploration and production,the converted wave exploration becomes a hot topic of current seismic exploration.We focus on the technique of converted wave processing,including static correction,orientation rotation,common converted point gather,four parameter anisotropic velocity analysis and pre-stack time migration,and set up the basic converted wave seismic data processing flow.We have checked this flow to seismic data of SLG area,and obtain a good result.
