注气压缩机的工况与储气库地层状态密切相关,在注气过程中,压缩机出口压力随地层压力升高而升高,变化幅度很大,在流程设计中要充分考虑适应这种变化。为此可采取两种措施The working condition of the gas injection compressor is closely related to the formation state of the gas storage reservoir. During the gas injection process, the outlet pressure of the compressor increases with the increase of the formation pressure, and the variation range is very large. Therefore, it is necessary to take this change into full consideration in the process design. Two measures can be taken:设置多级压缩机Set up multi-stage compressor;设置高低压天然气引。Set high and low pressure natural gas ejector.
