Problems solved by technology

[0003] Since the fluid parameters of the crude oil gathering and transportation system are in an unsteady state, such as instantaneous air volume, large liquid volume, and no flow such as plug flow, the instantaneous flow of crude oil gathering and transportation will be greatly changed, resulting in the key parameters that determine the effect of cyclone separation. —The linear velocity of the jet fluctuates in an excessively large range, which seriously weakens the effect of cyclone separation and reduces the actual separation and measurement accuracy

Embodiment Construction

[0037] see figure 1 , the present invention provides a multi-phase fluid cyclone separation device for two-stage mixed jet two-stage separation. ), a primary vertical cyclone separation pipe 5, a secondary inclined pre-separation pipe 6, a jet linear velocity stabilizing device 4, a secondary vertical cyclone separation pipe 7 and a forced swirl helicoid 8.

[0038] The working process of the present invention is: the gas-liquid two-phase mixed fluid rises and separates in the fluid stabilization pipe 1, and then enters the first-stage inclined pre-separation pipe 2 arranged obliquely, and is gradually separated into a stratified flow of upper gas phase and lower liquid phase. At the position close to the end of the first-level inclined pre-separation pipe 2, a height difference conversion pipe 3, that is, a pre-separation consolidation pipe, is arranged upward, and most of the gas phase components that have been precipitated in the first-level inclined pre-separation pipe 2 a...

Abstract

Disclosed is a turbulence separation device for multi-phase fluid, comprising a primary oblique pre-separation pipe (2), a primary vertical turbulence separation pipe (5), a secondary oblique pre-separation pipe (6), and a secondary vertical turbulence separation pipe (7). One end of the primary oblique pre-separation pipe (2) enters tangentially into the primary vertical turbulence separation pipe (5). The secondary oblique pre-separation pipe (6)leads out from near the end of the primary oblique pre-separation pipe (2). The end of the secondary oblique pre-separation pipe (6) enters into the secondary vertical turbulence separation pipe (7) tangentially. The turbulence separation device for multi-phase fluid is a series parallel dual-ejection and dual-separation device, with high measurement precision, low tolerance, and high stability.

Description

technical field [0001] The invention relates to a multi-phase fluid cyclone separation device, in particular to a device for the multi-phase fluid cyclone separation of the multi-phase fluid with a large density difference between two stages of mixed jets and two stages of separation. Background technique [0002] In the crude oil gathering and transportation metering system, especially in the wellhead single well metering system, the oil and gas separation system is commonly used to separate the gas phase and liquid phase extracted from the oil well, and measure the liquid phase quantity, gas phase quantity, and liquid phase water content in the crude oil respectively to calculate Oil production, realize the purpose of production measurement, support oilfield information management and decision-making, measurement, control, and provide basis and guarantee for improving oil production. Compared with traditional horizontal separators and vertical separators, cyclone separator...
