传统的方法在构建采油模型时，只考虑了惰性气体含量的增加对采油量的影响，很少考虑惰性气体在原油岩石中溶解的问题，浪费了大量的惰性气体，并且对采油率的增加效果不明显。针对传统算法构建模型的缺点，本文在充分考虑惰性气体在原油岩石中溶解度的基础上，提出了一种基于扩散机理的惰性气体扩散模型构建方法，引入气体的扩散机理，充分考虑了惰性气体在岩石中的扩散性与溶解性，并将惰性气体含量对原油粘度的影响考虑在内，采用数值方法构建惰性气体采油数学模型，提高了采油率，节省了惰性气体用量。实验研究表明，随着惰性气体含量的增加，采油量在上升，在同样惰性气体注入条件下，该模型能开采出更多的原油，提高最优采油量2020T，提高采油效率31.4%，有很强的实际应用价值。

Against disadvantages of traditional algorithm to construct model, based on the full consideration on the basis of the inert gas solubility in crude oil rock, this paper proposes a inert gas diffusion model building method based on the diffu-sion mechanism, the introduction of gas diffusion mechanism, give full consideration to the inert gas diffusivity and solubili-ty in the rock, and the influence of the inert gas content on the viscosity of crude oil into consideration, mathematical model and numerical method was used to construct inert gas extraction can improve the oil recovery rate, save the inert gas con-sumption. Experimental studies show that with the increase of the content of inert gas oil recovery is on the rise, under the condition of same inert gas injection, this model can produce more oil, improve the optimal production capacity of 2020 T, improve the efficiency of oil production by 31.4%, has a strong practical application value.
