Compact l-shaped column-cone combined tubular three-stage axial flow degasser

Abstract

The invention provides a compact L-shaped column-cone combined tube type three-stage axial flow degassing device, which is applied to the efficient separation of gas-containing fluids. The three-stage axial flow degassing device adopts the high-efficiency degassing technology of the vertical high-speed swirl field combined with the vertical pipe, horizontal pipe and T-shaped pipe, the horizontal fast axial flow field and the vertical reversing scrubbing field. The cyclone adjusts the oblique incident gas-containing fluid and forms a vertical high-speed cyclone flow. The first-stage degasser implements the first-stage segmented vertical high-speed cyclone degassing operation, removes most of the gas phase of the gas-containing fluid and forms The first-stage gas and the first-stage fluid, the microporous homomixer breaks the large particle size bubbles of the first-stage fluid to form a gas-liquid uniform flow, and the second-stage degasser implements the second-stage horizontal impeller to create a fast axial flow degassing operation , remove most of the gas phase in the gas-liquid homogeneous flow and form secondary gas and secondary fluid, and the third-stage degasser implements the third-stage vertical reversing deep degassing operation to remove a small amount of remaining liquid phase of the secondary gas And form tertiary gas and tertiary fluid.

Description

technical field [0001] The invention relates to a high-efficiency gas-liquid separation device in the field of oil and gas field development and exploitation engineering, in particular to a compact three-stage axial flow degassing device combined with an L-shaped tube, a column tube and a tapered tube, and its operation process. Background technique [0002] The high-efficiency degassing technology of gas-liquid two-phase flow has very important practical significance for the development and production of oil and gas fields. The main reason is that the high-efficiency degassing technology can effectively prevent slug flow and avoid The slug flow has an impact on the transmission pipeline and the equipment along the way. Second, the high-efficiency degassing technology can effectively reduce the bottom-hole back pressure during the production of oil and gas fields, thereby improving oil and gas recovery. [0003] Conventional gas-liquid two-phase separation devices are mainly...
