摘　　要：以东营凹陷滨三区滨348区块沙三下(沙河街组沙三段下部)火成岩为研究对象,根据测井、钻录井、岩心以及开发地震资料等综合分析,识别火成岩不同岩性、划分岩相,得出岩相分布规律,并建立了火山模式。通过研究分析,得出火成岩岩性以玄武岩为主,岩相以溢流相为主,并发育火山口相、火山通道相、侵入相等其他岩相。基于裂隙式喷发模式建立了串珠状裂隙式喷发和点状裂隙式喷发两种喷发模式。Taking the igneous rocks of Es3 in the Bin348 Block in Bin3 Area of the Dongying Depression as the research object,and based on the comprehensive analysis of logging,drilling and recording,cores,and development seismic data,different lithologies of igneous rocks are identified,lithofacies are divided,finally the lithofacies distribution law is obtained and the volcanic pattern is established.Through research and analysis,it is concluded that the lithology of igneous rocks is dominated by basalt,the lithofacies are dominated by overflow facies,and other lithofacies such as crater facies volcanic channel facies,and intrusive facies are developed.Based on the fissure eruption model,two types of eruption modes,bead-shaped fissure eruption,and point-shaped fissure eruption were established.
