针对阿姆河右岸某跨境气田井口压力平输压、资源流失、压力分布不均衡、增压投资大、审批难以及地面增压工程基建人员不足等影响产能目标完成的难题，开展了增压开采必要性和增压方案优化工作，研究表明，增压开采势在必行，集中增压、分期建设的增压方案最优：（1） 集中增压将所有压缩机部署在同一增压站内，分期建设既能降低资源流失，亦能缓解基建人员不足的问题；（2） 通过优化产能剖面和安装流程切换装置，增压总需求功率能降至43 MW，压缩机数量和利用率达到最优，实现了投资最小化、效益最大化。该方案已经获得资源国审批，13 台压缩机分两期投产运行，产能建设目标得以顺利完成，有效指导了地面增压工程的有序推进，提高了气田的开发效果。

The gas field lies astride the border between Turkmenistan and Uzbekistan is facing some problems which may affect the completion of productivity construction, such as well head pressure approaching transportation pressure, resource loss, uneven pressure distribution, the huge investment of supercharging and difficult approvals, the lack of personnel. Therefore, this paper did some researches about the necessity and optimization of supercharging. The study shows that supercharging can solve the above problems effectively, the supercharging plan of centralized and staged construction is optimum. Centralized supercharging installs compressors in the same station, but the construction can be carried out in two stages, which can not only minimize the loss of resources, but also alleviate the shortage of infrastructure personnel. By means of optimizing the production capacity profile and installing the flow switching devices in the booster station, the total required power of supercharging can be reduced to 43 MW, the number and utilization ratio of compressor are optimal, minimize investment and maximize benefits. The project has been approved by the resource country and 13 compressors have been put into operation in two stages, the production capacity construction target was successfully completed, effectively guiding the orderly progress of the project, the development effect of the gas field is improved.
