摘　　要：根据松辽盆地南部德惠断陷的钻井、测井和地震资料,针对营城组火山岩,将火山岩地震相进行分类,并描述各类地震相的地震反射及地质特征。将研究区火山岩地震相单元分为3类6种:3类为丘状、穿切状和席状;6种为简单中丘地震相、简单高丘地震相、复合中丘地震相、板状穿切地震相、丘状穿切地震相和席状披覆反射地震相。地震相分析可以有效识别该区的火山岩体,为进一步的火山岩勘探提供理论和技术参考。According to drilling data,well-logs and seismic data of volcanic rock,Dehui Fault Depression in south of Songliao Basin,this paper aims to describe the the earthquake reflection and geological characteristics of each kind of seismic facies according to Yingcheng formation volcanic rock.The seismic facies of the study area are divided into 3 kinds(mounded,wedged and sheeted)and 6 types(simple middle-mounded,simple high-mounded,composite middle-mounded,plated wedged,mounded wedged and sheet draped).Volcanic rocks in the study area can be identified by seismic facies analysis,and it provided theoretical and technical support for further volcanic rock exploration.
