反Q滤波是地震资料处理中提高成像分辨率的重要方法.设计和应用反Q滤波时,建立一个既简便又符合地下介质实际情况的Q数学模型和较准确地估算地下品质因子Q值是关键.前人对Q值估算和反Q滤波的研究取得了很多进展.本文简述了常用Q数学模型的理论基础,重点概括了各类Q值估算方法,分类介绍了各种反Q滤波补偿方法,预测了Q值估算和反Q滤波的发展趋势.

Inverse Q filtering is an important method to improve image resolution in seismic data processing. To build an easy mathematical Q model corresponding with real underground media and to estimate quality factor Q accurately are key when inverse Q filtering is designed and applied. Much progress has been made on the research of Q factor estimating and inverse Q filtering. Theoretical principle of usual mathematical Q models is described briefly, and Q factor estimating methods are summed up. Then inverse Q filtering compensation methods are presented respectively. At last, development trends of Q estimating and inverse Q filtering are predicted.
