| 摘 要： | 西部地区地下构造复杂,地层埋深较深,地震资料采集中,炮检距较大,地下介质的各向异性问题表现得较为明显。此时应用常规方法进行速度分析精度将变低,进而影响地震资料的成像质量。针对以上问题本文重点对VTI介质速度分析原理、各向异性参数求取方法进行了研究,并总结了一套各向异性参数求取的方法。通过模型试算和胜利西部资料的实际应用,表明各向异性速度分析技术是提高速度分析精度,改善成像效果的有效方法。

| Abstract: | The oil reservoir is buried deeply and the underground structures are complicated in west exploration area.When using large offsets to acquire seismic data,the anisotropy in seismic wave propagation becomes a serious problem.The usual methods of velocity analysis are not only inaccurate but also affect the quality of Migration imaging results.Aimed at existing problems of current seismic velocity analysis,the principle of anisotropic velocity analysis and the compute method of anisotropic parameter were mainly researched in this paper.Based on this research,a set of method suitable for evaluating anisotropic parameters is obtained.The application of both synthetic data and real data processing in Shengli west exploration block shows the method in analysis velocity and imaging is feasibly and effective. |
