稠油油藏蒸汽驱三维物理模拟及数值模拟研究的中期报告 摘要： 稠油油藏蒸汽驱是提高稠油开发效率的一种重要方法，对于模拟其动态过程和预测开发效果具有重要意义。本文针对某稠油油藏，进行了三维物理模拟和数值模拟研究，分析了蒸汽注入参数对于油藏开发效果的影响以及蒸汽驱过程中温度场、饱和度和孔隙压力的分布情况。初步结果表明，蒸汽注入时间、注入量和注入位置等参数对于油藏开发效果有着重要的影响，在一定条件下，蒸汽注入能够有效地提高稠油采收率。同时，模拟结果还表明，蒸汽驱过程中温度场呈现出明显的梯度分布，饱和度和孔隙压力也随着时间的推移而变化。 关键词：稠油油藏；蒸汽驱；三维物理模拟；数值模拟；开发效果 Abstract： Steam flooding is an important method to improve the development efficiency of heavy oil reservoirs, and it is of great significance to simulate its dynamic process and predict the development effect. In this paper, a three-dimensional physical simulation and numerical simulation research were conducted on a heavy oil reservoir, and the influence of steam injection parameters on the development effect of the reservoir and the distribution of temperature field, saturation, and pore pressure during steam flooding were analyzed. The preliminary results show that steam injection time, injection amount, and injection position have an important impact on the development effect of the reservoir. Under certain conditions, steam injection can effectively improve the recovery rate of heavy oil. At the same time, the simulation results also show that the temperature field during steam flooding presents a significant gradient distribution, and the saturation and pore pressure also change with time.
