摘　　要：为认识深部调驱作用机理、进一步掌握动态变化规律、优化试验方案,亟需开展深部调驱三维物理模拟实验,建立配套评价技术,明确效果影响因素,确保深部调驱矿场试验效果。通过物理模拟室内试验研究,对不同井网物模动态和深部调驱效果进行监测研究,评价实验效果,得出结论,优化油藏设计方案。为了进一步更加形象地研究深部调驱体系动态特征,进行了含油饱和度场的监测,绘制含油饱和度场变化图,得出了深部调驱体系有效的封堵高渗透层,扩大了波及体积,大幅度提高了采收率的结论,表明了井网不同对于深部调驱体系有很大的影响。In order to understand the mechanism of deep profile control and flooding effect, further understand the regular of dynamic variation, optimize the test program, it is very necessary to carry out the deep flooding dimensional physics simulation to establish the matching evaluation process and clarify the affecting factors. Through the indoor physical simulation experiments, physical simulation dynamic of different well network and effect of deep flooding were studied. Through evaluating the effect of experiments, the reservoir design project was optimized. In order to further more visually study dynamic characteristics of deep profile control and flooding system, oil saturation field change chart was drawn. Effective plugging high permeability layer of the deep profile control system was determined, the swept volume was greatly enlarged, and the recovery rate was improved. The study suggests that different well network has great influence on system of deep profile control.
