摘　　要：多元热流体吞吐技术在渤海油田开展稠油热采先导试验以来取得了较好的开发效果,但开发过程中出现的气窜问题较为严重影响了油田的生产。为了降低气窜的影响,本文从注采参数优化角度出发,通过建立海上典型井组模型,应用数值模拟对注入方式、气水比、注汽强度等关键注采参数进行优化,得到了最优结果。对比目前设计方案,同时结合现有多元热流体装置参数性能,得到了较优的注采参数推荐值,为后续多元热流体吞吐方案设计提供一定的指导和借鉴。The multi-component thermal fluid huff and puff technology has achieved good development results since the pilot test of thermal recovery of heavy oil was carried out in Bohai oilfield,but the gas channeling problem in the development process has seriously affected the production of the oilfield.In order to reduce the influence of gas channeling,this paper starts from the optimization of injection and production parameters,establishes a typical offshore well group model,and applies numerical simulation to optimize key injection and production parameters such as injection mode,gas-water ratio and steam injection intensity.Compared with the current design scheme and combined with the parameter performance of the existing multi-component thermal fluid equipment,a better recommended value of injection and production parameters is obtained,which provides certain guidance and reference for the subsequent multi-component thermal fluid huff and puff scheme design.
