南堡凹陷中浅层油源断裂与其他成藏要素的空间配置及控藏作用

为研究南堡凹陷中浅层油气成藏规律,在油源断裂及其他成藏要素空间分布特征分析基础上,采用叠合分析方法,对中浅层油源断裂与其他成藏要素空间配置特征及其对油气成藏的控制作用进行了研究,认为南堡凹陷中浅层是由油源断裂沟通的下生上储式生储盖组合,油源断裂与其他成藏要素空间配置对油气成藏的控制作用:①断层和油源配置关系控制着油气成藏平面范围;②断层与盖层配置关系控制着油气成藏的深度范围;③断层与砂体配置关系控制着油气成藏的层位;④断层与圈闭配置关系控制着油气成藏的部位。

The Space Distribution Characteristics of Faults Connected Source-rock and Oil-gas Accumulation Factors and the Function of Accumulation Controlling in the Middle and Shallow of Naupu Depression

In order to find the oil-gas accumulation law of middle and shallow strata in Nanpu depression,tbis study was hased on the analysis of space distribution characteristics of faults connected source rock and other oil-gas accu mulation factors. Matching relation between faults connected source-rock and other oil-gas accumulation factors and its controlling to oil-gas accumulation were studied on empirical basis. The result indicates that combination of gene-ration,reserw）ir and caprock of middle and shallow strata in Nanpu dep ration and upper reservoir combination. Controlling of matching betwee n belong to combination of lower gene- ts connected source rock and other ac- cumulation factors to oil-gas accumulation involves the following four aspects：①Matching relation between fault and source-rock controls plane areas of oil-gas accumulation; ② Matching relation heween fault and caprock controls depth areas of oil-gas accumulation; ③Matching relation between fault and sandstone controls oil-gas accumulation horizons;④Matching relation of fault and trap controls oil gas accumulation places.
