The invention provides an oil-water-gas three-phase separator, relates to the technical field of three-phase separators, and solves the technical problem that an existing vertical three-phase separator is relatively low in separation efficiency. The separator comprises a vertical separation tank, an inlet flow divider and a flow stabilizing device are arranged in the vertical separation tank, the flow stabilizing device is sleeved with the inlet flow divider, the inlet flow divider is communicated with a tangential inlet of the vertical separation tank, and the inlet flow divider can achieve pre-separation of gas and liquid. Multi-phase fluid entering the vertical separation tank from the tangential inlet enters the inlet flow divider to be subjected to gas-liquid pre-separation, so that a good preparation condition is created for subsequent three-phase separation, rapid and effective gas-liquid separation is realized, and the separation efficiency is greatly improved; and the flow stabilizing device also provides a stable laminar flow separation environment for oil-water two-phase separation.
Description
technical field [0001] The invention relates to the technical field of three-phase separators, in particular to an oil-water-gas three-phase separator. Background technique [0002] The oil-water-gas three-phase separator is the core equipment for the preliminary processing of oil well production fluid such as gas-liquid separation, oil-water sedimentation, and crude oil dehydration in the oil-gas gathering and transportation process. Oil well production fluid is a typical multi-component system, in which the water cut often exceeds 70%. Especially in the oilfields in the middle and late stage of development, the water content of the produced fluid even exceeds 90%. A considerable part of the contained water appears as free water. Oil and gas two-phase separation is to make the mixture reach equilibrium under a certain operating temperature and pressure, try to make the gas in the oil separate out, and the oil in the gas condense, and then separate it. The three-phase sep...
