Problems solved by technology

Due to the complexity of multiphase fluids, traditional single-phase metering methods cannot be applied, and multiphase metering methods are required
[0004] At present, the multi-phase metering media in China are mainly wellhead products, and there are relatively few studies on steam and water metering

Embodiment Construction

[0029] The invention relates to a steam-water heat phase separation metering device, which is mainly composed of a split sampler 1, an auxiliary separation tube bundle 2, a steam metering tube 3, a liquid metering tube 4 and a confluence tube 5. The split sampler 1 includes a central splitter tube 6 , distribution cylinder 7 , main fluid outlet pipe 8 , split fluid vapor phase outlet pipe 9 and split fluid vapor phase outlet pipe 10 . The inlet of the central distribution pipe 6 is connected with the steam-water two-phase flow pipeline, and the outlet of the central distribution pipe 6 passes through the front end plate of the distribution cylinder 7 and penetrates into the interior of the distribution cylinder 7; The inlets are connected, and the inlet of the main fluid outlet pipe 8 passes through the rear end plate of the distribution cylinder 7 and goes deep into the inside of the distribution cylinder 7 .

Abstract

The invention relates to a steam-water heat phase separation metering device. The steam-water heat phase separation metering device is mainly composed of a split sampler, an auxiliary separation tubebundle, a steam metering tube, a liquid metering tube and a confluent tube, wherein the split sampler is used for realizing equal sampling of the steam-water two-phase flow, the auxiliary separation tube bundle is used for enhancing separation of the sampling fluid, and the auxiliary separation tube bundle can be configured according to the sampling fluid amount in the application process. The two-way liquid metering process is set up to ensure accuracy of liquid metering at small flow rates. The device is advantaged in that simultaneous online measurement of steam, water flow and heat can berealized, and the device can be widely used in accurate measurement of the steam and water two-phase flow and heat in the heavy oil thermal recovery steam pipe network.

Description

Technical field: [0001] The invention discloses a steam-water calorie phase-separated metering device, in particular a device capable of simultaneously metering the flow and heat of steam and water two-phase flow. Background technique: [0002] Compared with ordinary crude oil, heavy oil has the characteristics of high viscosity, high density and poor fluidity. During the production of heavy oil fields, it is usually necessary to inject steam into the formation to increase the temperature of the heavy oil, thereby reducing the viscosity, improving its fluidity, and ultimately increasing the recovery factor. [0003] During the transportation process, the steam injected by the heavy oil exchanges heat with the environment, and part of the steam condenses to become wet saturated steam. Wet steam belongs to steam-water two-phase flow, and the enthalpy values ​​of steam and water vary greatly at the same temperature. The production effect is positively related to the heat of i...
