摘要：

在高分辨率层序地层解释的基础上,利用AVO(振幅随炮检距变化)处理过的三维速度场进行高分辨率AVO属性反演、谱分解、属性提取、波形分析等手段获得的储层信息与储层地震相和沉积相解释相结合,剖面-平面-立体处理、解释同步,赋予地震属性信息以正确的地质意义,达到对储层分布精细预测的目的。运用这一方法,对准噶尔盆地腹部莫西庄八道湾组一段进行了研究,结果显示,利用AVO属性反演和波形分析等处理手段得到的储层平面图与用高分辩率层序地层原理研究出的储层平面图有很好的叠合关系。

Abstract:

Based on high resolution interpretation of sequence stratigraphy,3-D velocity field processed with AVO is used to perform AVO attribute inversion,spectrum analysis,attribute attraction and wave form analysis to get reservoir information.Through combining the reservoir information with interpretation results of seismic and sedimentary facies of the reservoir,integrated seismic processing and interpretation in profile-plane-space is carried out to assign correct geologic meaning to seismic attribute information,so as to realize accurate prediction of reservoir distribution.This method has been used to study the first member of Badaowan Formation in Moxizhuang area,central of Junggar basin.The results show that the plane reservoir distribution achieved through AVO attribute inversion and wave form analysis has good coincidence with that achieved by using theory of high resolution sequence stratigraphy.

Key words: seismic processing, interpretation, integration, high resolution sequence statigraphy, accurate reservoir prediction
