Abstract
A pipe bundle natural gas flow calibration device is used for calibrating gas production line measurement in a natural gas field. An inlet pipe is connected with an inlet of a pipe bundle separating apparatus, an outlet of a gas gathering bag is connected with a gas separating pipeline, the other end of the gas separating pipeline is connected with an inlet of an orifice plate flowmeter, and an outlet of the orifice plate flowmeter is connected to a first valve through a flange. An outlet of a liquid gathering bag is connected with a water separating pipeline, and the other end of the water separating pipeline is connected with a second valve. A tee joint is connected between the first valve and the second valve through a flange, and a perpendicular connector of the tee joint is connected with a gas-liquid mixing discharge pipe. The pipe bundle natural gas flow calibration device has the advantages of being capable of calibrating a natural gas flowmeter of a natural gas well, checking measurement error of the natural gas flowmeter, reflecting variation situation of gas production rate of a natural gas well truthfully, and being high in accuracy. Simultaneously, separated liquid does not need to be discharged, thereby reducing the difficulty of transportation of sewage at the well head and environmental pollution.

Background technology
At present, metering and well head measured two kinds in the metering of traditional natural gas individual well was taked to stand.What metering process adopted in standing is to separate the back earlier natural gas is carried out the gas metering, gas dosing precision height, and the liquid meter error is big; The well head metering belongs to on-line metering.Present existing metering device is single-phase metering device, can't measure containing under the liquid status the big and aquifer yield of metering gas production error ratio.All can't realize the on-line metering of gas as single gas well gas liquid two-phase.
Chinese patent publication number: CN201809323U provides a kind of " bundled tube natural gas separator ", is applied to the natural gas gas-liquid separation.Natural gas air inlet header branches out many branch lines, connects many middle parts of separating tubing string with certain angle, separates tubing string top and connects the gas collection bag, and the bottom connects the liquid collecting bag; On the header of giving vent to anger, be fixed with orifice flowmeter; The liquid outlet of liquid collecting bag connects electronic tapping valve, and separating tubing string top has mist eliminator, and the drop of separating out in the mist eliminator flows into liquid back pipe, and the liquid back pipe bottom connects separates the tubing string bottom; Content gauge connects and separates the tubing string middle and lower part; Fluid level transmitter, orifice flowmeter have holding wire to connect acquisition controller.Effect is: at first carry out measuring after the gas-liquid rotational flow separation, eliminated the influence of liquid to the gas metering precision, improved measuring accuracy simultaneously, can realize gas metering, level monitoring, automatic drain.
The utility model content
The purpose of this utility model is: a kind of bundled tube gas discharge caliberating device is provided, realizes the demarcation of gas well natural gas flow meter, the error in dipping of checking natural gas flowmeter; Isolated liquid does not need to efflux simultaneously, reduces well head operation sewage roping difficulty.
The technical solution adopted in the utility model is: bundled tube gas discharge caliberating device, mainly by inlet tube, the bundled tube separator, separate the tracheae line, orifice flowmeter, valve, threeway, separate water pipeline, the gas-liquid mixed discharge pipe is formed, inlet tube is connected the import of bundled tube separator, at the top of bundled tube separator the gas collection bag is arranged, isolated natural gas focuses in the gas collection bag, in the bottom of bundled tube separator the liquid collecting bag is arranged, isolated liquid focuses in the liquid collecting bag, it is characterized in that: the outlet at the gas collection bag is connected with separation tracheae line, the other end that separates the tracheae line connects the inlet of orifice flowmeter, and the outlet of orifice flowmeter is connected with first valve by flange; Outlet at the liquid collecting bag is connected with the separation water pipeline, and the other end that separates water pipeline is connected with second valve; Between first valve and second valve, be connected a threeway by flange; The vertical port of threeway connects the gas-liquid mixed discharge pipe.
In order to show the water of bundled tube separator inside, be welded with connecting pipeline in the end of liquid collecting bag, content gauge of vertical connection on the pipeline, the upper end of content gauge is communicated with bundled tube separator middle part.
For easy to connect, be fixed with snap joint respectively in the end of inlet tube and the end of gas-liquid mixed discharge pipe.
The using method of bundled tube gas discharge caliberating device.Consult Fig. 2.The valve of well head gas producing device 12 is connected with the extraction pipeline, is connected with gas-liquid two flow meters 13 on the extraction pipeline, and 13 pairs of natural gas wells of gas-liquid two flow meters carry out that gas, fluid flow are monitored, record at ordinary times.Need carry out timing signal to gas-liquid two flow meters 13, the inlet tube 1 of the utility model bundled tube gas discharge caliberating device 14 is connected in the outlet of gas-liquid two flow meters 13.The mixing gas-liquid of extraction enters bundled tube gas discharge caliberating device 14, carries out gas-liquid separation, and isolated gas discharge is carried out high-precision measuring.After natural gas after the process metering and the liquid of separating mix, enter the gas well flow line from gas-liquid mixed discharge pipe 11.
The beneficial effects of the utility model: the utility model bundled tube gas discharge caliberating device, can demarcate the natural gas flowmeter of the natural gas well, verify the error in dipping of natural gas flowmeter, truly reflect the situation of change of gas well gas production, the precision height.Isolated liquid does not need to efflux simultaneously, reduces the difficulty and the environment pollution of the roping of well head operation sewage.
