摘要: 基于火山岩溢流相的高连续强振幅和火山通道相的低连续弱振幅2种截然相反的地震反射特征, 建立振幅-方差体地震属性分级-拾取-融合技术刻画火山岩时空展布的方法, 有效刻画火山岩的三维时空展布以及火山喷发期次.通过渤海湾盆地黄河口凹陷BZ34-9区带火山岩三维刻画和火山喷发期次研究, 取得以下认识: (1)研究区沙一二段火山岩零星分布, 主要发育在BZ34-9区带中部, 多为中心式喷发; 东营组火山岩广泛发育, 连片分布, 主要发育在BZ34-9区带南部缓坡带, 为中心式、裂隙-中心复合式喷发; (2)沙一二段东部火山先于西部火山喷发, 南部火山先于北部火山喷发; (3)东营组南部火山先于北部火山喷发, 且南部火山喷发期次多于北部, 北部火山多为短暂性喷发; (4)东营组火山较沙一二段活动强烈、喷发次数多、范围广.Abstract: A new method of seismic amplitude and variance cube thresholding display is proposed to enhance the description of the spatial and temporal distribution of volcanics and eruption phases in this paper, on the basis of the contrasting seismic reflections between volcanic channel facies (high continuity and strong seismic amplitude) and overflow facies (low continuity and weak seismic amplitude). Which has been applied and validated in the BZ34-9 block of Huanghekou Sag, Bohai Bay Basin. The study of 3D characterization of volcanics and eruption phases in BZ34-9 block leads to the follows conclusion. (1) Volcanics in the First and Second Members in the Shahejie Formation are located locally in the central part of study area, showing a central eruption style; whereas volcanics in the Dongying Formation are characterized by a widespread distribution in the southern gentle slope of study area, showing central, fissure-central eruption composite style. (2) For the First and Second Members in the Shahejie Formation, volcanic eruption in the eastern part is earlier than that of western part, while the southern one is earlier than that of northern one. (3) For Dongying Formation, volcanic eruption of the southern part is earlier than that of northern part, and the phases of the southern part are also more than those of northern part. (4) Compared to the First and Second Members of the Shahejie Formation, volcanic eruption in the Dongying Formation is characterized by more active, multi-period eruption, and widespread distribution.
