Research on Characteristics of Flow Field in Tubular Separation System of Offshore Production Platform
With the extension of offshore oilfield production time,the difficulty of producing fluid separation increases gradually.In order to satisfy the demand of separation speed and performance,and reduce the space,based on the production parameters of a platform in the South China Sea,the flow field characteristics of the pipeline separation system were numerically simulated and verified according to the field test data.Research shows that separated by T branch separators of the pipe separation system,free gas in the produced fluid can be basically separated from liquids.After the downstream oil-water mixture is treated by the cylindrical cyclone,the oil content of the water can be less than 30 mg/L,validating this technology can satisfy the demand of oil-gas-water separation of platform,and reveal the multiphase flow characteristic of the separation system.
