重力流

The effect of surface friction on the structure of front and frontogenesis is investigated by using the cloud model in which the large-scale deformation field is taken into consideration.

利用加入大尺度变形场作用的非静力模式，研究了地面摩擦对锋生和锋面结构的影响，在变形场锋生条件下，对不同模式格距、不同湍流参数化方案、不同变形场强度、考虑与不考虑地面摩擦等情形进行了比较，在考虑地面摩擦拖曳作用后得到了类似重力流结构的边界层锋面特征。

Meanwhile the nonhydrostatic and high-resolution character and physical processes contained in the cloud model can be made use of. In this way some of the difficulties met in the fully description can be overcome. So we can investigate the effect of surface friction on the frontogenesis in the boundary layer in high-resolution nonhydrostatic model. The structure of the front obtained through this approach is consistent with the observation.

在高分辨率情况下研究了地面摩擦对边界层内锋生的作用，从而得出比较精细的、与实际观测相一致的类似重力流的边界层内锋面结构特征，说明了地面摩擦对锋生和锋面结构的重要影响，这是以往数值模拟还没有得到的结果。

重点分析了赋存于太原组第四——第五灰岩层位间的A层火山事件沉积，提出了火山碎屑水下重力流事件沉积的概念，并建立了形成模式。

Fully considering the factors of structure, deposition, transforming system and Reservoir Forming Dynamics and so on, the paper thought that the reservoirs in Xiakou fracture zone belong to hydrocarbon remigration and secondary accumulation mode, the configuration relationship between the sands and faults is the main factor that affects hydrocarbon migration; reservoir gathers in the central upheaval zone belong to event hydrocarbon migration and accumulation mode, it can be divided into three styles, they are the fracture activity event mode, the volcanic activity event mode, he gravity flows event mode. The key factors of resulting in event reservoir are fault cyclicity and episodic characteristic.

充分考虑构造、沉积、输导体系和成藏动力等因素，分析认为：夏口断裂带油气藏聚集属于油气再运聚成藏模式，连通砂体与断层的配置是影响油气运移的主要因素；中央隆起带油气藏聚集属于油气事件成藏模式，划分为断裂活动事件成藏模式、火山活动事件成藏模式和重力流事件油气成藏模式三类，断层活动的旋回性和幕式性是诱发事件成藏的关键因素。
