摘　　要：乳状液作为一种新型的调驱体系,可以通过在多孔介质中的贾敏效应发挥流度控制作用,抑制驱油体系的窜进。在实施乳状液调驱时,不但要考虑体系的调堵能力,同时还需要综合考虑体系的注入性能。乳状液渗流不同于传统的牛顿流体渗流,其在多孔介质中的渗流压力不但受到自身黏度的影响,同时还受到吸附、滞留等作用的影响。本文基于乳状液的等效流动黏度建立了注入压力预测模型,采用Matlab编程软件定量计算了不同注入参数和注入方式下的流动阻力,该计算方法可以根据现场注采设备的基本性能,优选出复合体系的注入速度与注入量,在保证复合体系具有良好的调驱能力下还有良好的注入性,本研究为现场乳状液调驱施工提供了一种可行的定量设计方法。As a novel flooding system,emulsion flooding system can control the fluidity and prevent the intrusion of oil displacement system by utilizing the Jamin effect in porous media.However,when implementing emulsion flooding,both the plugging capability and the injectivity of the system need to be considered.However,emulsion seepage is differed from the traditional Newtonian fluid seepage,and its seepage pressure in the porous medium is not only affected by its own viscosity,while also affected by adsorption,retention and other effects.Therefore,this study develops an injection pressure prediction model based on the equivalent flow viscosity of the emulsion system.Using Matlab programming software,the flow resistance under different injection parameters and methods is quantitatively calculated.This calculation method can select the optimal injection rate and volume of the composite system based on the basic performance of the field injection and production equipment.It ensures that the composite system has good displacement efficiency while also achieving good injectability.This study provides a feasible quantitative design method for on-site emulsion flooding construction.
