Description
Technical field
The utility model relates to steam flow, mass dryness fraction measuring equipment, particularly high steam-water two phase flow metering device.
Background technology
In the heavy crude heat extraction process, general steam injection mode adopts the central heating supply mode, use steam injecting pipe that steam is caused every a bite steam injection well, generally the steam injection for every mouthful of individual well adopts the method for average, be that boiler output steam flow is divided by the well number of steam injection, and just put undue emphasis on the boiler export mass dryness fraction for mass dryness fraction, then adopt estimation algorithm for the actual mass dryness fraction that arrives every mouthful of individual well, can find out from above steam injection technology, flow for the individual well steam injection, the mass dryness fraction metering, do not consider the inhomogeneous mass dryness fraction deviation that causes of mass dryness fraction and the heat waste in the steam course of conveying in the assigning process, then do not consider bottom to the impact of gettering ability for the metering of flow, finally cause the waste of steam so that affect crude output.
The utility model content
The purpose of this utility model is to provide a kind of high steam-water two phase flow metering device, has solved the problem that can't measure steam injection in the heavy crude heat extraction process.
The purpose of this utility model is achieved in that a kind of high steam-water two phase flow metering device, comprise the throttling element that is installed in the carbonated drink conveyance conduit, throttling element is divided into the upstream side tube chamber that is positioned at the throttling element upstream side with carbonated drink conveyance conduit tube chamber and is positioned at the downstream tube chamber in throttling element downstream, throttling element has the throttle orifice that penetrates its body, the upstream side tube chamber is communicated with the downstream tube chamber by throttle orifice, the carbonated drink conveyance conduit is positioned at the intraluminal pipe perisporium of upstream side and is arranging and center on the uniform tap hole of its body hoop and around its body and be positioned at along the toroidal container of the tap hole outer circumferential side of annular spread, outside carbonated drink conveyance conduit tube chamber, steam-water separator is being set, steam-flow meter, water ga(u)ge and restriction choke, the upstream side tube chamber is communicated with the annular collection chamber that forms in the toroidal container by tap hole, annular collection chamber is by the carbonated drink influent stream mouth that head piece is communicated with steam-water separator that goes out of toroidal container shell wall setting, the venthole that the steam-water separator topmost arranges is communicated with the carbonated drink reflux pipeline by steam-flow meter, the delivery port water flow meter that the steam-water separator foot arranges is communicated with the carbonated drink reflux pipeline, and the carbonated drink reflux pipeline is communicated with the downstream tube chamber by restriction choke.
Operating principle of the present utility model is: the carbonated drink conveyance conduit is positioned at the intraluminal steam-water mixing fluid of water saving fixtures upstream side successively through tap hole, annular collection chamber enters steam-water separator, steam-water separator again steam-water mixing fluid is separated into independent vapor stream and current, independent vapor stream and current by steam-flow meter vapor stream and the current by water ga(u)ge together be back to the tube chamber that the carbonated drink conveyance conduit is positioned at the water saving fixtures downstream by carbonated drink reflux pipeline and restriction choke, the steam-flow meter that data collection processor collects the most at last and data that water ga(u)ge is surveyed and data that line pressure is surveyed are carried out operational analysis production flow line steam flow, mass dryness fraction, pressure, temperature, the required parameter such as heat.The utility model and line pressure meter, data collection processor are used, the utility model advantage is: measurement category is wide, range of flow 0.2-23 ton, mass dryness fraction scope 10-100%, measure 370 ℃ of peak bulk temperatures, maximum is born pressure 22MPa, and certainty of measurement is high, and flow, dryness measurement deviation guarantee in 3%; Can uninterrupted on-line measurement (data collection processor corresponding have the functions such as data storage, forwarding, analysis).The utility model has solved the problem that can't measure for a long time steam injection in the heavy crude heat extraction process, for Petroleum Production provides first-hand steam injection data, so that steam injection becomes known quantity, for directive function has been played in adjusting, the allotment of steam injection, with raising and the raising recovery ratio that plays the steam injection quality.Matching the data collection processor that uses with the utility model can be accurately, in real time to steam injection in the heavy crude heat extraction process measure, store, forwarding and analytic function.
