摘要

摘要我们研究了向油藏注入二氧化碳和水在多孔介质中引起的三相流动。我们构建了一个流动数值模型，该模型因油气之间的相变和气体相对渗透率的滞后变化而变得复杂。该模型与采油盈利能力的经济估算相结合。通过数值模型，我们估算了滞后对交替注入水和二氧化碳的最有利策略的影响。我们表明，滞后行为要求注入更大量的气体才能实现利润最大化。

Studying the Effect of Hysteresis of Relative Phase Permeability on Optimal Strategies of Water-Gas Impact on Oil Reservoirs

We investigate three-phase flows in porous media caused by carbon dioxide and water injection into an oil reservoir. We construct a numerical model of the flow complicated by the phase transitions between oil and gas and the hysteresis changes in the gas relative permeability. The model is coupled with the economic estimates of the profitability of oil recovery. Using a numerical model, we estimate the effect of the hysteresis on the most profitable strategies of the alternating injection of water and carbon dioxide. We show that the hysteresis behavior requires the injection of larger volumes of gas to maximize the profit.
