Rapid separation and metering device for multiphase flows

Abstract

The invention discloses a rapid separation and metering device for multiphase flows, and relates to the technical field of oil field equipment. The rapid separation and metering device comprises a separation tank, a liquid level control tank and a control box; a device frame is arranged at the bottom end of the separation tank; the device frame is circularly provided with a ring-shaped pipe; one side of the ring-shaped pipe is communicated with a feeding port; a separation mechanism is arranged on the ring-shaped pipe; the separation mechanism is coiled outside the separation tank and is communicated with the inner parts of the ring-shaped pipe and the separation tank; the top end of the separation tank is connected with the top end of the liquid level control tank through a pipeline I; the bottom end of the separation tank is connected with the bottom end of the liquid level control tank through a pipeline IV; the top end of the liquid level control tank is communicated with a pipeline VI through a pipeline II; the upper part of the liquid level control tank is communicated with the pipeline VI through a pipeline III; the lower part of the liquid level control tank is communicatedwith the pipeline VI through a pipeline V; and a liquid level meter is arranged on the tank body of the liquid level control tank. The rapid separation and metering device for the multiphase flows iscapable of achieving the aim of rapid separation and continuous metering of the multiphase flows.

Description

Technical field: [0001] The invention relates to the technical field of oilfield equipment, in particular to a multiphase flow rapid separation metering device. Background technique: [0002] Crude oil single well metering is convenient for grasping the general distribution of underground oil reservoirs in oilfields, and is of great significance for oil production management. Liquid production in a single well is multi-phase, intermittent pulse flow, irregular and unstable, so the separation and measurement of crude oil in a single well has always been an urgent and difficult problem to solve. [0003] Existing single well metering generally includes glass tube metering, software metering, etc. Glass tube metering is a traditional method commonly used in domestic oilfields. Volumetric method is used to measure oil intermittently to convert production. Due to irregular and unstable single well production, Repeated measurement is required to take the average value, especially...
