【摘要】济阳坳陷具有北断南超的构造特征,在北部陡坡带广泛发育类型多样、储层复杂、油水关系特殊的砂砾岩扇体油藏,由于极端的非均质性和油气分布的复杂性,其常规测井曲线特点与一般的砂岩储层存在明显不同,过去的解释方法也不适用.通过分析砂砾岩扇体油藏的储层岩性变化,提出了1套相对适用有效的储层识别、油水层判识和油藏参数的解释方法,在实际应用中精度明显提高,为砂砾岩扇体油藏的深化勘探和储量计算奠定了基础.%Jiyang depression is structurally characterized by faulting in the north and overlapping in the south, having multiple categories of complicated glutenite fan reservoirs with special oil - water relationship widely developed in the northern steep slope. Due to extreme heterogeneity and the complexity of oil/gas distribution, the conventional log features of these reservoirs differ greatly from those of the ordinary sandstone reservoirs and the existing interpretation methods are not applicable. In this paper, a set of methods that can effectively identify the reservoirs, oil and water formations and interpret reservoir parameters have been proposed based on analyzing the changes of lithology of the glutenite fan reservoirs. These methods have been applied in practice and obviously the accuracy has improved, which has laid a
foundation for further exploration and reserves estimation of glutenite fan reservoirs.
