摘要

勘探实践表明徐家围子断陷营城组火山机构是深层天然气藏良好的储集体。本文以徐家围子断陷中部营城组火山岩为研究对象,该区火山岩厚度大,爆发相、喷溢相和火山沉积相等各种相带均较发育,通过对火山岩地震反射特征的系统分析,总结了各种相带的具体震相特征。并以此为依据,应用趋势面属性、相干体分析技术等多种手段,对火山机构的空间分布进行了识别与预测,在营城组共识别出44个火山锥,对本区火山岩气藏的勘探开发具有一定的指导作用。
Exploration and practice shows that volcanic edifice of the Yingcheng Formation in Xujiaweizi Fault Depression are mainly deep gas reservoirs.Volcanic rocks of this area are large thickness,there are some types of volcanic facies,including extrusive facies,effusive facies,volcanic-sedimentary facies and so on.Based on analysis of volcanic rocks of Yingcheng Formation in Xujiaweizi Fault Depression,this paper studies seismic reflection features of volcanic rocks,and summarizes volcanic seismic identifier for different volcanic facies.And by the application of variety techniques,such as tectonic trend surface analysis,coherence analysis,the paper predict and identify the spatial distribution of volcanic edifice,Yingcheng Formation has identified forty-four volcanic cones.This achievement may guide the exploration and development of volcanic gas reservoirs in this area.
