Problems solved by technology

The traditional grid type does not greatly improve the flow characteristics of the equipment. The main reason is that the effective flow section of the component is relatively large, and the flow length is relatively short, so the flow stabilization and rectification effects are not obvious enough.

Embodiment Construction

[0015] Such as figure 1 As shown, the separator of the present invention is a horizontal three-phase separator. The upper ends of the separator cavity 1 are respectively provided with an oil-gas-water inlet 2 and a gas outlet 3. The separator cavity 1 below the separator oil-gas-water inlet 2 is used as a ring-shaped fixing part 4 to connect with the rectification device 5. In the rectification A coalescer 10 is provided on one side of the device 5; a weir plate 6 is provided in the separator cavity 1 below the gas outlet 3. Both sides of the weir plate 6 are respectively provided with a water phase outlet 7 and an oil phase outlet 8 . In order to facilitate maintenance, a manhole 9 is also provided on the separator.

[0016] The working principle of the separator is: the oil-gas-water mixture enters the separator cavity 1 from the oil-gas-water inlet 2, along the figure 1 The medium flow direction flows through the rectifying device 5 so that unstable flow states such as...

Abstract

The invention relates to a rectifying device of a horizontal oil-gas-water triphase separator, which mainly comprises a separator body and is characterized in that the rectifying device adopts a semicircular structure formed by splicing n ( n is larger than or equal to 1) splicing type pore plates; openings are not formed at the two ends of the spliced semicircular structure, and small holes are densely formed at the middle position between the two ends; and the rectifying device and a separator cavity are connected in a way that each pore plate body of the rectifying device is fixedly connected with a corresponding part of a ring-shaped fixing part on the separator cavity, and after the connection, a semicircular cavity is formed between the upper end part of the rectifying device and a connecting part. With the rectifying device adopting the structure, the complex three-dimension flow at the front of the pore plates can be effectively rectified to the relatively uniform two-dimension planar flow, the flow behavior of the equipment can be remarkably improved, and phenomena of back flow and back mixing can be basically eliminated.

Description

technical field [0001] The invention relates to a rectifying device of a horizontal oil-gas-water three-phase separator, which belongs to the field of structure development of petroleum processing equipment. Background technique [0002] The oil-gas-water three-phase separator is one of the most commonly used equipment in the oilfield development and production process. The coalescing oil-water separation process requires that the flow field in the main separation area should be uniform and stable, and the larger the main separation area, the more uniform and stable the flow field , the better the separation effect. The inlet component can only play the role of energy dissipation, so a rectification device needs to be installed to even out the liquid flow. The traditional grid type does not greatly improve the flow characteristics of the equipment. The main reason is that the effective flow section of the component is relatively large, and the flow length is relatively shor...
