稠油油藏泡沫溶解气驱过程非常复杂。由于传统的贫化试验的局限性，一些微观因素对这一过程的影响还没有完全了解。本研究旨在通过实验和模拟研究泡沫溶解气驱。首先，通过室内实验研究了压力衰竭速率对临界含气饱和度和泡沫溶解气驱过程的影响。其次，一个新的三维泡沫油模型，捕捉泡沫溶解气驱的许多重要特征，如非平衡行为，气体演化动力学，和粘性力对气体流动性的影响，开发。最后，系统地研究了影响泡沫溶解气驱效果的重要参数，并在一个典型的泡沫油藏中进行了模型应用。结果表明，新模型能够模拟实验室和现场尺度上泡沫溶解气驱中观察到的许多异常行为。高原油粘度、高衰竭速度、长填砂时间和低溶解气油比可获得高采收率。泡沫溶解气驱过程对衰竭速率、长度和临界气体饱和度敏感。原油粘度、溶解戈尔比和扩散系数不是敏感因素。
Foamy solution-gas drive processes in heavy oil reservoirs are very complex. The influence of some microscopic factors on this process is not fully understood due to limitations of traditional depletion tests. This study aims to investigate foamy solution-gas drive by experiments and simulations. First, the effects of the pressure depletion rate on critical gas saturation and foamy solution-gas drive processes were investigated by laboratory experiments. Second, a new three-dimensional foamy oil model that captures many important characteristics of foamy solution-gas drive, such as non-equilibrium behavior, gas evolution kinetics, and the effect of viscous forces on gas mobility, was developed. Last, the effects of some important parameters on foamy solution-gas drive were systematically investigated,and a model application was conducted in a typical foamy oil reservoir. The results indicate that the new model is capble of simulating many of the unusual behaviors observed in foamy solution-gas drive on a laboratory and field scales. High oil recoveries were obtained with a high oil viscosity, high depletion rate, long sandpack, and low solution gas-oil ratio. Foamy solution-gas drive processes are sensitive to the depletion rate, length, and critical gas saturation. The oil viscosity, solution GOR and diffusion coefficient are not sensitive factors.
