摘　　要：介绍了VSP多波波前扩散校正理论推导和方法研究程序研制等方面工作 ,并对油区的VSP多波资料做了波前扩散校正处理。VSP多波亮点、瞬时振幅、瞬时频率、瞬时相位等参数与钻井资料联合起来能标定地震多波亮点与瞬时信息等参数对油气藏的反映 。This paper presents the work on theoretical derivation of wavefront divergence for multiwaves in VSP and development tips of the related software. The multiwave data from work areas are processed with the proposed method. The relation between bright spots as well as instantaneous parameters of seismic multiwaves and hydrocarbon reservoirs can be determined by combining parameters such as bright spots, instantaneous amplitude, instantaneous frequency and instantaneous phase with well data, thereby it will help to improve the veracity of interpretation for seismic multiwaves.
