摘　　要：随着油田生产开发的持续开展,作为我国最大的碳酸盐岩储层油藏系统的塔河油田,在碎屑岩储层中也取得了良好的勘探成果。三叠系阿克库勒组下砂岩段内发育下油组,对下油组砂体构型特征的研究能够指导复杂构造区域油藏描述及油田剩余油的挖潜。本次研究将阿克库勒组的辫状河三角洲沉积进行了精细划分,识别出5类砂体构造类型,通过对3种砂体构型组合样式的总结,并结合大量野外露头分析,建立了辫状河砂体构型数据库。With the continuous development of oilfield production and development, Tahe oilfield, as the largest carbonate reservoir system in China, has also achieved good exploration results in clastic reservoirs. The Lower Oil formation is developed in the lower sandstone member of Triassic Akekule formation. The study on the sand body architecture characteristics of the Lower Oil formation can guide the reservoir description in complex structure area and tap the potential of the remaining oil in the oilfield. In this study, the braided river delta deposits of Akekule formation are finely divided, and five types of sand body structure are identified. Through the summary of three sand body architecture combination styles and combined with a large number of field outcrop analysis, the braided river sand body architecture database is established.
