摘　　要：目前,中国大部分油气田已步入中后期开发阶段,气井生产压力不断降低、产量严重递减,受新旧区块集输管网系统产能和集输处理能力的制约,存在地面集输管网系统效率低和气田稳产难度大的问题。围绕气田中后期开发中面临的关键问题,系统地总结了包括气田集输管网系统布局与流量分配优化技术、增压方案优化技术以及地下地上一体化优化技术等在内的气田集输管网系统优化关键技术。以增压优化为重点,从增压工艺选择、增压时机确定和增压方案优化等方面对气田集输管网系统增压优化技术研究现状进行了分析,认为基于模型分解策略的分布式优化技术是解决大规模气田集输管网系统增压优化问题的可行方案。探讨了耦合考虑储层-井筒特性的气田集输管网系统增压优化技术的具体实施策略和可能面临的问题,对气田集输管网系统增压优化技术发展进行了总结,以期为气田稳产提供技术借鉴。Currently,the majority of China's oil and gas fields have entered the middle-to-late stages of development,facing a continuous decline in well pressure and a significant reduction in production.Challenges,including low efficiency in gathering network systems and difficulties in maintaining stable gas field production,arise due to limitations in the production capacity of gas,as well as the gathering and processing capabilities of gathering network systems in both new and old blocks of gas fields.Focusing on the key challenges in the middle and late stages of gas field development,this paper systematically summarizes critical technologies for the optimization of gas field gathering network system,which consists of the techniques for layout and flow allocation optimization,pressure boosting scheme optimization,and integrated optimization for both underground and surface facilities.With a focus on pressure boosting optimization,this paper provides a comprehensive review of the current research status on boosting optimization technology for gas field gathering network systems.It covers three aspects:pressure boosting process selection,determination of optimal pressure boosting timing,and optimization of pressure boosting schemes.The paper suggests that distributed optimization technology based on a model decomposition strategy is a viable solution for addressing the pressure boosting optimization challenges in large-scale gas field gathering network systems.Building upon this foundation,this paper further explores specific implementation strategies and potential challenges for pressure boosting optimization technology in gas field gathering network systems,taking into account the coupled consideration of reservoir-wellbore characteristics.Finally,this paper concludes with a summary on the development of pressure boosting optimization technology for gas field gathering network systems,aiming to provide technical insights for maintaining stable production in mature gas fields.
