摘　　要：在地震层序划分的基础上对春光区块沙湾组二段进行地震相类型研究。通过井震结合和砂体扫描解释分析其构成地震响应的岩性组合,结合沉积环境对沙二段沉积相特征展开研究,认为沙二段为扇三角洲—水下扇沉积模式,主要分布扇三角平原、扇三角洲前缘、前扇三角洲、斜坡扇、盆底扇5种沉积相。其中斜坡扇和盆底扇最为发育,为油气藏勘探的有利相带。This paper studies the seismic facies of Shawan Formation 2 in Chunguang area based on the division of the seismic sequence. By means of well -seismic combination and sand body scanning and interpretation, it analy- zes the lithology combination of the seismic response, and studies the sedimentary facies characteristics of Shawan Formation 2 combined with sedimentary environment. The sedimentary model is fan delta - underwater fan. Shawan Formation 2 includes 5 sedimentary facies fan delta plain, fan delta front, pro - fan delta, slope fan, and basin floor fan. The slope fan and basin floor fan are well developed and meaningful for reservoir exploration.
