摘　　要：油气田进入开发后期,产气量受输气压力和用户用气情况的影响而随时发生变化,按照原来生产规模设计的天然气压缩机组,需要通过旁通打回流运行才能解决输气量的变化问题,存在很大的能量浪费,因而需要节能改造。结合某集气站天然气压缩机组出现的运行问题,分析了采用不同气量调节方式进行节能改造的可行性,提出和确定了液压可变余隙调节法作为节能改造的方案,并对改造内容进行了详细介绍。对比改造前后压缩机组的运行功率发现,改造后压缩机组节能效果明显。During the later stage of oil and gas field development, the gas production varies at any time due to changes of gas pressure and users＇ gas needs. As a result, the compressor units designed and selected according to the original production scale have been unable to meet the current production needs. They require bypass-backflow operation to solve production capacity variation problem. This paper introduces the operation problems of natural gas compressor units in a gas gathering station, and analyzes the feasibility of energy-saving with different capacity control methods. Through the analysis, the hydraulic variable clearance adjustment method is proposed and identified as the energy-saving retrofit scheme, and the reformation content is described in detail. Through comparing the compressor operational power difference before and after the reformation, it is found that the energy-saving effect is obvious.
