斜坡沉积体系中的砂质碎屑流沉积是斜坡带的主要储集体类型,也是现阶段储层研究的热点之一。随着大陆勘探程度的不断提高,由陆向海过渡的斜坡带是今后勘探领导的新战场。基于此,本研究具有前瞻价值和实际指导意义。作者利用沉积模拟实验技术,考虑不同的斜坡长度、坡度和湖水深度,详细分析了点物源碎屑流形成深切谷和发育碎屑流的临界坡度、高差,深入探讨了斜坡带上砂质碎屑流形成及发育的控制因素,细致刻划了点物源碎屑流沿坡折带搬运方式、演化特征及其沉积作用规律。
Sediment deposition in the slope sedimentary system is the main type of reservoir in the slope zone and is also one of the hotspots in reservoir research at present. With the continuous improvement of exploration in mainland China, the transition from Lu to Hai Sea is the new battlefield for future exploration and exploration. Based on this, this study has the value of forward-looking and practical guidance. Based on the sedimentary simulation experiment technique and considering the different slope length, slope and lake depth, the authors analyzed the critical slope and elevation of debris flow in point source deep deep valley and development debris flow in detail. The formation and development of debris flow control factors, a detailed description of the point source debris flow along the slope break zone handling mode, evolution characteristics and depositional law.
