摘要： “海洋石油123”FPSO原油冷却器为板式换热器，正常一用一备。随着油田产油量逐渐上升，原油冷却器的负荷逐渐加大，导致换热效果不佳。通过对油田原油进行物性分析，导致冷却器换热效果不佳的主要原因在于原油含蜡量多，析蜡点较高，原油侧板片壁面结蜡严重，使得原油与海水的热交换能力下降。为高效解决该问题，对原油冷却器的设备结构和流程状态进行了全面分析，创造性提出将2台冷却器改造为串联运行，并现场验证了冷却器串联的应用效果，为今后FPSO的稳定运行提供参考依据。

Abstract: The “Hai Yang Shi You 123”FPSO crude oil cooler is a plate heat exchange, which normally operates with one in use and one as backup. As the oil production in the oilfield gradually increases， the load on the crude oil cooler gradually increases， resulting in poor heat exchange efficiency. Through physical property analysis of oilfield crude oil， the main reason for the poor heat exchange effect of the cooler is that the crude oil has a high wax content， a high wax precipitation point， and severe wax deposition on the side plate wall of the crude oil， which reduces the heat exchange capacity between the crude oil and seawater. To efficiently solve this problem， a comprehensive analysis was conducted on the equipment structure and process status of the crude oil cooler. A creative idea was proposed to optimize the two coolers into series operation， the application effect of the cooler series connection was verified on site， providing a reference for the stable operation of FPSO in the future.

Key words: FPSO, crude oil cooler, optimize
