摘　　要：针对海上A油田烃气驱开发过程中的气窜问题,采用物理模拟方法,对不同气窜治理技术适应性进行分析。实验结果表明,降低注气速度适用于注气开发早期,但优势渗流通道形成后,调整注气速度对气窜作用较小。优势渗流通道形成后注气端可采用泡沫调堵进行治理,生产端可通过封层等措施进行治理。气窜治理技术适应性分析为气窜防控方案的制定和优化提供了依据。In response to the gas channeling problem during the development of hydrocarbon gas drive in offshore A oilfield,physical simulation methods were used to analyze the adaptability of different gas channeling control technologies.The experimental results show that reducing the gas injection rate is suitable for the early stage of gas injection development,but after the formation of optimal permeability channel,adjusting the gas injection rate has little effect on gas channeling.After the formation of optimal permeability channel,the gas injection end can be treated by foam plugging adjustment,and the production end can be treated by sealing and other measures.The adaptability analysis of gas channeling control technology provides a basis for the formulation and optimization of gas channeling prevention and control plans.
