Problems solved by technology
The gas production and gas-liquid ratio of deep-water natural gas fields will fluctuate continuously during the development and production process, and the fluctuation degree is relatively large. It is difficult for conventional separators to achieve high-efficiency separation during the entire life cycle of natural gas field development.
At present, some separators are suitable for high liquid content separation, and there will be a problem of low separation efficiency when the liquid ratio is small; There are often problems such as liquid phase fragmentation and entrainment, resulting in low separation efficiency
