摘　　要：针对松辽盆地兴城气田深层砾岩应用常规粒度分析方法无法实现的难点,运用图像粒度分析方法对研究区深层砾岩粒度特征进行分析,并在图像二维粒度特征分析基础上,结合深部砾岩的基本沉积特征进行沉积环境分析,认为兴城地区深层砾岩为向辫状河三角洲过渡的砾质辫状河型扇三角洲成因,这为该区气藏的下一步勘探部署提供必要的地质依据。Aimed at the problem of deep conglomerate in Xingcheng Gas Field of Songliao Basin,where it was impossible to carry out conventional grain-size analysis methods,and the iconic grain-size analysis was carried out to analyze the grain-size. Characteristics of deep conglomerate in the studied area,and based on the iconic two-dimension grain-size analysis,and in combination with the fundamental sedimentary characteristics of the deep conglomerate,the sedimentary environment was analyzed. It is considered that this area is the generated shallow gravel-bed braided fluvial fan deltas transition to braided fluvial delta,it provides an important geological basis for the next exploration of gas reservoirs in Xingcheng Gas Field.
