摘　　要：南海某海洋石油平台的天然气压缩机在运行过程中产生多次关停,给作业公司带来了大量的经济损失。经过分析所有的停机原因,其中无油流开关误报警导致的停机占比最大,而且一直没有得到有效的解决。为了减少因无油流开关误报警触发停机给油田带来的经济损失,作业公司决定对天然气压缩机的注油管路进行改造,采用在注油管路使用两组无油流开关和压力变送器,软件的控制逻辑增加表决机制。通过改造,因无油流开关误报警导致的停机很少发生,同时也通过新增的变送器采集到了注油管路的脉动压力,为天然气压缩机注油管路的进一步诊断、分析、维护提供了直接的数据依据。在不降低原来的安全性的基础上,提高系统的可用性,得到了更多的数据支持,也挽回了经济损失。The natural gas compressor on an offshore platform in South Sea shut down for a couple of times,bringing great eco-nomic loss for the operation company.After analyzing all reasons of the shutdown,they found the biggest reason of shutdown was false alarm from the no-flow timer which had not been resolved.In order to reduce the economic loss for the oilfield caused by false alarm from the no-flow timer,the operation company made transformation for the oil filling pipeline of natural gas compressor.They applied 2 sets of no-flow timer and pressure transmitter on the oil filling pipeline and added voting mechanism on the con-trol logic software.Benefited by the transformation,the operation company substantially decreased the shutdown probability and collected the pulsating pressure of oil filling pipeline from the added transmitter at the same time,which provided visual data for further diagnose,analysis and maintenance of gas compressor oil filling pipeline.This method can improve the system usability,obtain more data support and save losses without decreasing security.
