[Abstract]:As the theoretical system of turbidity flow and clastic flow becomes more and more mature, the fluid transformation process of gravity flow is paid more and more attention, and the concept of mixed event layer associated with it comes into being. The mixed event layer is a sedimentary record of single clastic flow or turbidite flow transformation and is a vertical sedimentary combination of rheological characteristics. The typical mixed event layer sedimentary sequence is characterized by five sections (i.e. pure sandstone segment H _ 1, banded sandstone section H _ 2, viscous shredded rock segment H _ 3, wave bedding section H _ 4, massive mudstone section H _ 5T), and there is usually a lithologic abrupt interface inside the section. The mixed event layer is developed within the coarse grain delta, the transitional zone between submarine fan and waterway and tongue body, the lateral margin of tongue body, the distal end and the restricted marginal area of micro-basin, and its vertical overlay thickness can reach tens of meters. The discovery of mixed event layers is of great significance to the study of the spatial rheological properties of gravity fluid and gravity flow sediments, and also promotes the study of reservoir configuration and heterogeneity. It provides a new idea for further exploration of favorable reservoir sand bodies in deep water. The establishment of hybrid geophysical identification method and the flexible application of related concepts in the study of lake gravity flow will be the next research direction.
