| 摘 要： | 高含水油田剩余油分布研究是一个世界性的难题。应用储层流动单元进行油气储层评价研究自 2 0世纪 80年代后期以来受到了石油工作者的广泛重视。文中以辽河油田欢 2 6断块为例 ,应用储层流动单元 ,在沉积微相分析的基础上研究高含水油田剩余油分布特征。密闭取心井岩芯分析资料表明剩余油饱和度与储层流动单元间存在良好的对应关系 ,在此基础上建立了利用流动单元流动带指标计算剩余油饱和度的方法。沉积微相内部对应着多个流动单元类型的组合 ,不同的沉积微相其流动单元组合形式也不同 ,表现出的渗流能力亦存在较大的差异性 ,从而为表征流体渗流的平面差异性和评价剩余油分布奠定了坚实的基础。研究结果表明 ,欢 2 6块剩余油平面上主要分布在中部和东部的构造较高部位。在本研究成果指导下 ,4口井 6个月累计增产原油 4 556t ,取得了良好的地质应用效果。

| Abstract: | Residual oil distribution in high water containing oilfield is a worldwide difficult problem. Extensive attention has been paid to reservoir evaluation by using reservoir flow unit since the last of 1980s. In this paper, on the basis of sedimentary microfacies analysis, reservoir flow unit is applied to study remaining oil distribution properties in Block Huan26 of Liaohe Oilfield that is in the high water containing period. Cored data show that there is a favorable relationship between residual oil saturation and reservoir flow unit, and the equation for calculating remaining oil saturation is established based on flow zone index(FZI). The microfacies is made up of various flow units. The assorted forms of various flow units and the seeping capacity are different among various microfacies. The result shows that flow unit is provided with advantage in describing plane otherness of fluid seeping and in evaluating distribution properties of remaining oil, and that the residual oil is distributed mainly over the central section and the relative high height of the east section of the faulting block. Obvious geological effect has been obtained in Block Huan26. |
