    摘要:

    为解决北部湾盆地福山凹陷花场地区流一段剩余油滞留现象严重、注采效果差等问题,结合该区实际情况,利用岩心、测井、录井等资料,对福山凹陷花场地区流沙港组一段储层的层内、层间和平面非均质性进行研究。结果表明,研究区层内非均质性较强,受沉积构造的影响,储层层内渗透率变异系数、突进系数和极差整体较强,均值系数普遍偏低,Ⅱ、Ⅳ油组的夹层分布相对较多;层间非均质性主要受层厚、砂厚以及隔层厚度的影响,不同层位差异较大。平面非均质性受砂体及沉积微相展布影响,不同地区表现出较强的非均质性。综合得出,研究区内位于河道内的Ⅱ、Ⅳ油组为剩余油分布的有利区域。

    Abstract:

    In order to solve the oil remaining serious,injection and extraction effect issues in Huachang field of Fushan sag,combined with the actual situation in the region,using the core data,logging data,layer,interlayer and plane heterogeneity of Huachang field flow for a period in Fushan oilfield were studied. The results show that the coefficient of variation of permeability,the coefficient of the breakthrough and the range of the reservoir in the first section of the flow field are stronger,and the mean coefficient is lower. From the interlayer distribution,the study area flow reservoir Ⅱ and IV oil group is relatively strong;the study area is mainly affected by the strong reservoir heterogeneity,sedimentary structure,permeability heterogeneity,interlayer distribution and non control factors such as particle size rhythm;interlayer heterogeneity is mainly affected by the thickness,sandstone thickness and interlayer thickness. Large differences exist in different horizons. The plane heterogeneity is influenced by the distribution of sand bodies and sedimentary microfacies. It is concluded that the oil reservoirs in the study area are favorable for the remaining oil distribution.
