摘 要：
综合岩心、电性及相关地质统计分析资料,对塔河油田三叠系下油组强底水油藏夹层的成因类型、分布特征及夹层对剩余油的控制作用进行了研究。划分识别了泥质、钙质和物性三类夹层。夹层成因和分布特征主要受沉积、成岩作用控制,夹层平面分布形式呈连片分布、孤立透镜状分布及不规则冲刷充填沉积。夹层的性质、发育规模及发育位置决定了剩余油的富集程度,并就夹层控制剩余油的挖潜方式进行了探讨。

摘 要：
Through analyzing the cores,logging data and geological statistics,the genetic types and distribution characteristics and the control of interlayer on the distribution of residual oil of interlayer in the strong bottom water reservoir were studied in the lower oil formation of Triassic in Tahe Oilfield.Interbed was divided into muddy intercalation,calcareous intercalation and petrophysical intercalation.Origin and distribution characteristics of the interlayer were mainly controlled by sedimentary and diagenetic effect.In the plane,the interbed was in continuous distribution,isolated lenticular distribution and irregular eroded filling deposit.The interlayer properties,development scale and development position determines the degree of remaining oil enrichment,and the way of tapping the potential of remaining oil that is controlled by interlayer is discussed.
