摘要

针对化学驱中原油乳化后多相流体微观渗流规律认识不清的问题,采用格子Boltzmann方法描述连续相流体渗流行为,并结合浸入边界法描述乳状液滴运移行为,引入乳状液滴弹性变形力学方程,建立微孔隙尺度的乳状液滴渗流数学模型。通过非均质孔道数值模拟,研究不同粒径、黏性及弹性的乳状液滴在孔道中的输运变形特征,定量分析乳状液滴在大孔道形成滞留封堵后的液流转向行为,明确乳状液滴界面流变特性对非均质孔道流体渗流的影响。结果表明:当乳状液滴粒径接近于孔道尺寸或大于孔道尺寸时,封堵后液流转向作用明显;高黏度和高弹性液滴使周围流体渗流速度波动幅度增大,孔道中流体渗流速度及流量显著降低;乳状液滴粒径因素(粒径为3、8 μm)对于扩大波及体积贡献率为6.99%,乳状液滴黏性因素(液滴与外部连续相黏度比为1、5)对于扩大波及体积贡献率为3.46%,乳状液滴弹性因素(弹性参数为200、70)对于扩大波及体积贡献率为6.75%。研究成果对明确乳状液调驱机理有重要意义。

Abstract

Aiming at the insufficient understanding of the multiphase fluid microscopic seepage laws after crude oil emulsification in chemical flooding, the lattice Boltzmann method was used to describe the seepage behavior of the continuous phase fluid, combined with the immersed boundary method to describe the migration behavior of emulsion droplets. The mechanical equation for elastic deformation of emulsion droplets was introduced to establish a mathematical model for emulsion droplet seepage at the micro-pore scale. Through numerical simulation of heterogeneous pores, the transport and deformation characteristics of emulsion droplets with different particle sizes, viscosities and elasticities in pores were studied. The fluid diversion behavior after emulsion droplets form retention plugging in large pores was quantitatively analyzed and the influence of the interfacial rheological properties of emulsion droplets on fluid seepage in heterogeneous pores was clarified. The results indicate that the fluid diversion effect after plugging is obvious when the emulsion droplet size is close to or larger than the pore size; high viscosity and high elasticity droplets increase the fluctuation amplitude of the surrounding fluid seepage velocity, and significantly reduce the fluid seepage velocity and flow rate in the pore; the contribution rate of the emulsion droplet size factor (particle sizes of 3 and 8 μm) to expanding the sweep volume is 6.99%, the contribution rate of the emulsion droplet viscosity factor (viscosity ratio of droplet to external continuous phase of 1 and 5) is 3.46%, and the contribution rate of the emulsion droplet elasticity factor (elastic parameters of 200 and 70) is 6.75%. The research results are of great significance for clarifying the mechanism of emulsion profile control and flooding.
