摘要: 含水率与驱替倍数关系曲线作为研究水驱油规律的一条重要曲线,对油田水淹规律、剩余油挖潜以及含水率上升规律有着重要的指导作用。但在实验过程中,由于受岩心尺寸较小及高黏原油水油流度比的影响,在无水采油期、低含水期甚至中含水期无法获取准确的实验数据,出现了曲线异常现象。因此,建立了含水率与驱替倍数数学关系式,并对渤海部分稠油油田水驱实验得到的含水率与驱替倍数三类异常曲线进行了校正,根据校正后曲线对M5⁃2油田进行了水淹图绘制,进而指导该油田剩余油挖潜。

Abstract: As an important curve to understand the law of water flooding, the relationship between water cut and displacement multiples plays an important guiding role in understanding the rules of oilfield flooding, tapping the remaining oil and the law of water cut. However, during the experiment, due to the small size of core and high viscosity of crude oil and water, the accurate experimental data can not be obtained during the dry recovery period, the low water cut period or the middle water cut period, and the abnormal curve appears. The paper creatively establishes mathematical relation between water cut and displacement multiple, and corrects three kinds of abnormal curves of water cut and displacement multiple obtained from water flooding experiments in some heavy oilfields of Bohai Sea. According to the corrected curve, the water flooded map of M5⁃2 oilfield is drown up,which guides the remaining oil tapping the potential of the field.
