摘　　要：针对靖边气田某增压站RTY1250型天然气压缩机组夏季运行发动机夹套水温过高,造成停机次数频繁等问题,采用CFD软件对机组空冷器散热能力开展热力学分析。基于分析结果对机组空冷器上方发动机排气尾管进行改造。结果表明:发动机排气尾管改造对降低发动机夹套水温具有可行性,改造后高温尾气对于空冷器顶部的影响范围变小,有助于提高空冷器散热量;经过现场改造,得到改造后天然气压缩机组夹套水温最高出现在下午15—18时,最高温度为88℃,比改造前降低了5℃,日平均温降为3.84℃,有效地减少了RTY1250压缩机组高温停机次数。In order to solve the problem that the engine jacket water temperature of RTY1250 natural gas compressor in a pressurization station in Jingbian Gas field is too high in summer,which causes frequent downtime,CFD software is used to carry out thermodynamic analysis of the cooling capacity of the unit’s air cooler.Based on the analysis results,the engine exhaust tailpipe above the unit air cooler is reformed.The research results show that the engine exhaust tailpipe transformation is feasible to reduce the engine jacket water temperature,and the influence range of high temperature exhaust gas on the top of the air cooler is smaller after the transformation,which is helpful to increase the heat dissipation of the air cooler.After the on-site transformation,the highest water temperature of the jacket of the natural gas compressor unit after the transformation appears at 15:00~18:00,and the highest temperature is 88℃,which is 5℃lower than before the transformation,and the average daily temperature is 3.84℃,which effectively reduced the number of high-temperature shutdowns of the RTY1250 compressor unit.
