The Brained River Delta, as an important type of coarse clastic sedimentary system, the establishment and deepening of its sedimentary model have core value for guiding oil and gas exploration and development as well as geological engineering practice. Based on the classic definitions, this paper systematically reviews a variety of characteristic Brained River Delta sedimentary models proposed in recent years, including blanket type and Gilbert shallow Brained River Delta under shallow water conditions, "flood genetic type" Brained River Delta dominated by seasonal flood events, and Near source sandy and distal fine-grained Braided River Delta controlled by source distance and climate. And the arid Brained River Delta formed under the background of an arid climate. The article expounds the sedimentary background, formation mechanism and identification characteristics of various models, and points out that the research on these fine models has greatly enriched and developed the theoretical system of Brained River Delta, providing key geological basis for effectively predicting the "sweet spot" of high-quality reservoirs and reducing exploration risks.
