摘要：

在泡沫驱替实验系统基础上,研制了多孔介质中流动泡沫结构图像的实时采集实验装置，实现了在高压实验状态下岩心出口端以及中部测压点处流动泡沫微观结构的实时动态观察和图像采集。该实验装置包括气液注入、泡沫渗流模拟、图像采集和产出流体分离计量系统。同时建立了相应的泡沫结构图像处理和定量表征方法，定义了泡沫等效直径、体积比例频度分布、分布密度和非均匀度等特征参数，可对渗流过程中泡沫结构变化规律进行定量描述和统计。研究表明，泡沫体系在岩心中是逐渐趋于分布均匀和稳态的过程。泡沫驱替稳定后，距离入口端越远，泡沫体积越小，均匀度越高，泡沫越稳定，且封堵压差也越大。

Abstract:

A real-time image acquisition device for detecting foam textures as bubbles flowing in porous media was developed with the foam flooding experimental system. Dynamic observation and image acquisition of flowing-foam microstructures were achieved at the outlet and the middle pressure-measuring position of cores under a high-pressure experimental condition. This experimental device is composed of a gas-liquid injection system, foam-seepage simulation system, image acquisition system, and a separation and measurement system of produced fluid. Correspondingly, image processing and quantitative characterization methods for describing foam textures were also established. In order to carry out the quantitative characterization and statistical analysis of foam textures during the seepage process, we defined some characteristic parameters including the equivalent diameter of bubbles, frequency distribution of the volumetric proportion, and distribution density and maldistribution of bubbles, with which quantitative and statistical descriptions could be given for change rules of foam textures during the seepage process. Experimental results showed that the bubble distribution in cores became gradually homogeneous and steady during the process of foam flooding. When bubbles reach a steady state, a longer distance from the inlet of cores can result in a smaller bubble volume, a higher homogeneity, a more stabilizing distribution and a bigger difference in plug pressure.
