摘　　要：随着天然气源的大量发现与注天然气提高采收率技术的不断完善,注天然气开发稠油油藏已成为提高稠油采收率的重要技术手段。针对某油田深层稠油油藏的地质及开发特点,在室内实验和相态拟合的基础上,建立了油藏数值模拟模型。利用历史拟合调整后的组分模型对注天然气吞吐提高深层稠油采收率方案参数进行了优化。根据参数优化方案,使注天然气吞吐开发深层稠油油藏取得了较好的增油降水效果。With the discovery of a mass of natural gas resources and the continuous improvement of EOR technology by natural gas injection process,the heavy oil reservoir developed by natural gas injection process has become significant technical means for EOR.In view of the geology and exploitation of deep heavy oil reservoir in an oil field,based on the lab experiment and phase behavior simulation,this paper builds up the numerical simulation model for such a reservoir,and optimizes the parameters of the EOR program by cyclic natural gas injection process using the compositional model after history match and modification.According to the parameter optimization program of deep heavy oil reservoir by cyclic natural gas injection process,good effects of incremental oil production and reducing water cut have been gained.
