根据渤海某重质油田浮式生产储卸装置（FPSO）的多级紧凑式气浮（CFU）试验结果以及渤海某重质油田井口平台上的多级紧凑式气浮设备的运行状况进行分析研究。根据试验数据，FPSO上的两级紧凑式气浮试验设备除油率高；井口平台上的三级紧凑式气浮设备处理后，生产水中含油降至27 mg/L左右。多级紧凑式气浮工艺在海上重质油田应用效果好，两级紧凑式气浮即可代替斜板除油器及浮选器，且多级紧凑式气浮占地面积小、重量轻，适合在海上应用。
Research is carried out according to the data from a multi-stage compact flotation unit （CFU） experiment on a floating produced, storage and offloading unit （FPSO） in a heavy oilfield, as well as the running data of CFU on a wellhead platform in a heavy oilfield. The oil removal rate of two-stage CFU is high, according to the experiment data from FPSO. The oil content in produced water after three-stage CFU on the wellhead platform is decreased to about 27 mg/L. So, the multi-stage CFU can achieve a good result in offshore heavy oilfield. A two-stage CFU can replace corrugated plate interceptor and gas floator. Besides, the multi-stage CFU is small and light, which is suitable to offshore oilfields.
