基于VSP地震资料的品质因子提取方法

Extraction Method of Quality Factor based on VSP Seismic Data

    摘要
  • 摘要: 介绍了改进的频谱比方法原理、影响因素及其优点，并利用改进的谱比法对胜利油田某工区采集到的VSP地震资料进行测试，对所有下行反射波进行振幅谱计算。结果显示，该方法使得提取出来的品质因子Q值计算精度得到了提高，计算结果更加真实可靠。

     

    Abstract: This paper studies VSP data in shengli oilfield with advanced spectral ratio method to improve the calculation accuracy of quality factors. Different from traditional spectral ratio method in which only direct waves from VSP data are used to calculate, the advanced one takes all downgoing reflected waves to calculate amplitude spectrum, whose results will be more authentic and reliable.
