| 摘 要： | AVO技术可以得到描述地下介质的多方面信息,这对油气勘探具有非常重要意义.但在实际应用中,子波干涉和上覆层影响等因素使常规AVO技术的效果受到很大影响.本文利用积分法求取AVA道集、引入子波和反演手段来消除上述因素的影响,提高了AVO分析的分辨率.因而,使AVO分析技术用于薄层地质现象研究成为可能.

| Abstract: | AVO technique can obtain much information of subsurface media.It is very significant for oil and gas exploration.However,in practice AVO technique is seriously effected by the factors of wavelet interference and above-covered layers.This paper applies three methods,which are getting AVA gather by integral access, using wavelet and inversion means,to eliminate the effects of the factors and to improve AVO resolution.Therefore,it is possible that AVO technique will be applied to studying thin layers. |
