渤海某油田透平发电机组供气流程优化与效果分析

Optimization and Effect Analysis of Gas Supply Process for the Turbine Generator Set in an Oilfield in Bohai Sea

渤海某油田燃料气处理系统为透平发电机组提供燃料气,为了提高供气稳定性,通过优化流程运行参数,提高海管运行压力,调整流程控制模式,升级应急处置程序,成功实现了在不影响富余气外输的前提下,利用天然气海管为主机燃料气扩容增储的目的,延长了应急工况下透平发电机组燃气模式运行时间,降低了透平发电机组的燃油费用和油田发生非计划性关停的风险。

The fuel gas treatment system of an oilfield in Bohai mainly provides fuel for the turbine generator set.In order to improve the stability of gas supply,the process has been successfully implemented by optimizing process operating parameters,increasing subsea pipeline operating pressure,adjusting process control modes,and upgrad emergency handling procedures.The goal of using natural gas submarine pipelines to expand increase storage of fuel gas for the main engine without affecting the transmission of surplus gas has been successfully achieved.The project effectively proves the gas supply stability of the turbine generator set,reduces the risk of unplanned shutdown of the oilfield and the fuel cost of the turbine generator set.
