储集层沉积于水体动荡、氧化性强的过补偿环境，如冲积扇相、河流相、滨浅湖相、三角洲相、浊积扇相、风成相、浅海相等。
Reservoir formed in the turbulent and oxidized environment, for example alluvial fan facies, fluvial facies, delta facies, aeolian facies aad shallow-sea facies etc.
黑石渡组属于向上变细层序，早期为冲积扇沉积，中期为洪泛平原、决口扇和扇三角洲沉积，晚期为深湖浊流沉积。
HsdF developed the fining upward sequences, and alluvial fan in the early stage, floodplain and crevasse splay and fan delta in the middle stage, and lacustrine turbidites in the late stage.
结合沉积微相分析，应用岩心分析化验资料对冲积扇内部储层质量差异及其分布特征进行了研究。
In combination with sedimentary microfacies analysis, we study the quality differences and distribution of reservoirs within the alluvial fans by using core analysis and testing data.
