摘要
根据孤东油田七区中馆 4～ 6储层的实际地质情况 ,从沉积非均质性、构造非均质性及流体非均质性等方面入手 ,揭示了七区中馆 4～ 6储层非均质性的控制因素及剩余油在平面上和垂向上的分布模式 ,分析了储层非均质性对剩余油的控制作用。指出利用储层非均质综合指数等值线图可进行剩余油富集预测。
Based on the practical geological situations of Zhongguan 4～6 reservoirs in Region 7 of Gudong Oilfield, the control factors of heterogeneity of these reservoirs in the region and horizontal and vertical distributional modes of remaining oil are revealed, the control of reservoir heterogeneity on the remaining oil is analyzed from the aspects of sedimentary, structural and fluid heterogeneity It is pointed out that the prediction of remaining oil enrichment would be made by using an aggregative index isogram of the reservoir heterogeneity
