摘　　要：地震波的吸收衰减规律和地震资料的品质因子反演一直是地球物理学家研究的重要领域之一。目前大部分研究还只是停留在理论层面,实际应用研究较少。该文将零偏移距VSP Q值估计层Q和变偏移距VSP估计有效的Q值相结合的方法应用于胜利油田中,结果表明该方法较为适用、可行。The attenuation law of seismic waves and the quality factor of the seismic data inversion have been one of the important areas which geophysicists study. At present, most of the research is only on the theoretical level, and the practical application is less. In this paper, the combination of methods that zero-offset VSP estimated layer Q value and walkaway VSP estimated effective Q value were application in the Shengli Oilfield. The results show that the method is applicable and feasible.
