| 摘 要： | 储层的非均质性严重影响着油田开发效果,储层平面展布特征、纵横向的连续性、储集物性的平面变化规律和层间物性的差异程度等都是描述储层非均质特征的重要内容.本文研究了枣南油田孔一段储层内部连续或不连续分布的非渗透性泥质夹层的特征及其分布规律,论述了各沉积微相区的非渗透性泥质夹层的分布特征,并定量地评价了储层的非均质性,同时用非渗透性泥质夹层分布频率和非渗透性泥质夹层分布密度这两个定量指标来预测了非渗透性泥质夹层分布的平面变化规律,为储层地质模型的建立及合理评价储层提供了依据.

| Abstract: | The heterogeneous characteristics of reservoir has a great effect on the efficiency of reservoir development. This paper studies the charactrifltics and the destribution pattern ofthe muddy impermeable intercalation in the reservoir of southern Zaoyuan oilfield. Theheterogeneous characteristics of reserveir is quantitatively evaluated by the use of the twoquantitative indexes, namely muddy unpefmeable intercalation distribution frequency and density, the distribution variation of the muddy unpermeable intercalation. The results are useful for promoting the efficiency of the development of Zaoyuan oilfield. |
