摘要
为了研究下生上储式生储盖组合油气成藏规律,在油源断裂及其确定方法研究的基础上,采用油源断裂与受其控制形成油气藏之间分布关系分析的研究方法,在南堡凹陷中浅层地区对油源断裂对下生上储式油气成藏与分布的控制作用进行了研究。结果表明,油源断裂对油气成藏平面分布的控制作用主要表现在:油源断裂分布控制着油气成藏的分布范围;油源断裂转换带是油气成藏分布的有利部位。油源断裂对油气成藏剖面分布的控制作用主要表现在:油源断裂所断至的区域性盖层上下附近是油气聚集的有利层位;油源断裂上盘是油气聚集的有利部位。
To sludy the nil-gas accumulation law of the lower generation and upper storage reservoir pattern and based on the study of fanlt connecting source rock and reseroir and its determinatinn method, the control of the fault connecting source rock and reservoir on lower generation and upper storage pattern oil-gas accumulation and distribution in middle-shallow area of Nanpuby Depression is studied by analyzing the relation between fault connecting source rock and reservoir and oil-gas reservoir controlled by it. The result indicates that the enntrol of fault connecting source roek and reservoir on oil-gas accumulation plane distribution mainly reflects in the following two aspects： the distribution of fauh connecting source rock and reserw^ir controls the distribntion range nf oil-gas aeeumulation; the transition zones of fault connecting source rock and reservoir are the favorable sites of oil-gas accumulation and distribution. The control of fault cnnnecting source rock and reservoir on the distributinn site of oil-gas aecumulation profile distribution mainly also reflects in the following two aspects： the regional cap rock broken by fault connecting source rock and reservoir and near its upper and lower layers are the favorable layers of oil-gas accumulation; the upper wall of fault connecting source rock and reservoir is the favorable site of oil-gas accumulation.
