Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing:

[0025] Such as figure 1 As shown, the present invention includes a degassing main road 3 and a gas branch 35, the function of the degassing main road 3 is to separate the gas in the produced liquid, and the function of the gas branch 35 is to remove water mist and oil mist in the gas .

[0026] The structure of degassing main road 3 includes inlet flange 1, gas-liquid separator 4, flowmeter 5 and outlet flange 9, and inlet flange 1, gas-liquid separator 4, flowmeter 5 and outlet flange 9 pass through the pipeline in sequence in series. In the above structure, the gas-liquid separator 4 is the core component, through which the gas in the oil well production fluid can be separated online and the liquid volume can be measured separately, thereby effectively improving the measurement accuracy.

[0027] The structure of the gas branch 35 includes a one-way valve 6 and a demis...

Abstract

A wellhead liquid production degassing metering device relates to the field of wellhead metering devices for oil wells, including a main degassing road and a gas branch. The structure of the main degassing road includes an inlet flange, a gas-liquid separator, a flow meter and an outlet flange. The inlet flange, the gas-liquid separator, the flowmeter and the outlet flange are connected in series through pipelines; the structure of the gas branch circuit includes a one-way valve and a demist device connected in series through the pipeline, and the inlet port of the gas branch circuit is connected to the The gas outlet of the gas-liquid separator is connected, and the outlet end of the gas branch is merged into the main degassing road at the outlet end of the flowmeter. The invention separates and measures the gas in the oil well production liquid on-line by means of on-line degassing, thereby effectively improving the measurement accuracy.

Description

technical field [0001] The invention belongs to the field of wellhead metering devices for oil wells, and in particular relates to a wellhead fluid production degassing metering device. Background technique [0002] In the process of oil field production, it is necessary to measure the liquid flow produced by the wellhead of the oil well. At present, the measurement method is simply to use a flow meter to measure. The disadvantage of this metering method is that the wellhead production fluid often contains oil layer gases such as natural gas, and the doping of these gases in the production fluid will affect the measurement accuracy of the production fluid. For this reason, it is necessary to design a wellhead fluid production degassing metering device to improve the measurement accuracy of wellhead fluid production. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention provides a metering d...
