摘　　要：油气优势运移通道研究是勘探目标评价的重要内容,其形成主要受输导层的非均质性、通道产状和运移动力3种"要素"控制。结合计算分析和针对苏北盆地高邮凹陷XJZ油田的油气运移模拟实验,进一步论述了油气优势运移通道形成中"三要素"的作用机理。"三要素"中"动力"要素是核心,控制着油气运移的趋势和方向;"产状"要素对"动力"要素起约束作用;"非均质性"要素决定着油气能否运移以及运移速度。油气优势运移通道实际上是"三要素"综合作用的结果。The analysis of prevailingpetroleum migration pathways can help evaluate petroleum exploration targets. Three factors control migration pathways,including the heterogeneity of carrier beds,the attitude of migration pathways and fluid dynamic force. A case study was made in the XJZ oilfieldin the Gaoyou Sag,North Jiangsu Basin,to considerthe controlling effects on petroleum migration pathways. Fluid dynamic force plays a core role and controls the direction of petroleum migration. The attitude of pathways constrainsfluid dynamic force.The he-terogeneity of carrier beds determines whether petroleum can migrate and the velocity of migration. Petroleum migration pathways are determined bythe interaction of three factors.
