【摘要】 随着油气勘探开发的不断深入,地震勘探技术已从常规三维地震勘探向三维三分量勘探方向发展。本文针对三维转换波各向异性精确成像的关键技术难题,在综合分析转换波速度各向异性特性及表征方法基础上,研究了各向异性高精度速度分析及叠前时间偏移处理技术。该技术已在大庆探区三维三分量地震资料处理中取得了较好的效果。更多还原

【Abstract】 With the development of oil exploration and production,the trend of the seismic exploration technique has been moved from routine 3D exploration to 3D 3C exploration.Regarding the key technique problems in 3D converted wave anisotropy imaging,the anisotropy high precision velocity analysis and pre-stack time migration processing technique were studied in this paper based on the integrated analysis for the anisotropy characteristics of the converted wave and the representation methods,by using the technique excellent results were achieved in the 3D 3C seismic data processing in Daqing exploration area.更多还原
