The gas-liquid two-phase flowmeter further comprises a flow pattern sorting device, a static mixer, an inverse stabilizing device and a vortex precession flowmeter. The flow pattern sorting device in vertical arrangement is connected with an inlet tube, of which the upper port is connected with an outlet tube through a piping. The vortex precession flowmeter is arranged on the piping. The lower port of the flow pattern sorting device is sequentially connected with the inverse U-shaped tube, the static mixer, the Venturi tube and the inverse stabilizing device. A differential pressure sensor is arranged on the Venturi tube. The inverse stabilizing device is connected with the outlet tube. The gas-liquid two-phase flowmeter overcomes the problem of high cost and inconvenient operation in the prior art.
Description
Technical field
The utility model relates to the field mining equipment technical field, is specifically related to a kind of gas-liquid two-phase flow instrument.
Background technology
The metering of oil field individual well product is the major issue in the product of oil field always, and along with the development of oilfield exploitation technology, this problem is more and more important.Traditional solution is to build a large amount of test satellite locations in oilfield surface engineering, approximately per tens mouthfuls of wells need be built a test satellite location, every mouthful of well is laid the pipeline that leads to test satellite location, utilize separating tank that the tolerance and the liquid measure of oil well are measured on test satellite location, every mouthful of well metering was converted and is whole day output in 1-2 hour again.This method cost height, operation are also inconvenient.
Summary of the invention:
The utility model provides a kind of gas-liquid two-phase flow instrument, to overcome the problem of the high and inconvenient operation of cost that prior art exists.
For overcoming the problem that prior art exists, technical scheme provided by the utility model is: a kind of gas-liquid two-phase flow instrument, comprise Venturi tube, inverted U pipe and sensor, also comprise the flow pattern collating unit, static mixer, reverse stabilising arrangement and precession vortex flowmeter, described vertically disposed flow pattern collating unit links to each other with inlet pipeline, its upper port links to each other with outlet conduit by pipeline, pipeline is provided with the precession vortex flowmeter, the lower port of flow pattern collating unit is connected to the inverted U pipe successively by pipeline, static mixer, Venturi tube and reverse stabilising arrangement, Venturi tube is provided with differential pressure pickup a; Described reverse stabilising arrangement links to each other with outlet conduit.
On the pipeline between flow pattern collating unit and the precession vortex flowmeter, also be provided with temperature sensor and pressure transducer; The inverted U pipe is provided with differential pressure pickup b.
The utility model is simple in structure, removes the measuring system of water percentage, and can satisfy the requirement of measuring tolerance and liquid measure; Because most of gas is metering after the flow pattern collating unit separates, and has improved measuring accuracy greatly, avoided when atm number because the error that the difference of gas, flow velocity is brought; And need not to carry out the experience correction according to the difference of operating mode at the scene, greatly made things convenient for on-the-spot user.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of gas-liquid two-phase flow instrument, comprise Venturi tube 8, inverted U pipe 11 and sensor, its special character is: also comprise flow pattern collating unit 2, static mixer 10, reverse stabilising arrangement 7 and precession vortex flowmeter 5, described vertically disposed flow pattern collating unit 2 links to each other with inlet pipeline 1, its upper port links to each other with outlet conduit 6 by pipeline, pipeline is provided with precession vortex flowmeter 5, the lower port of flow pattern collating unit 1 is connected to inverted U pipe 11 successively by pipeline, static mixer 10, Venturi tube 8 and reverse stabilising arrangement 7, Venturi tube 8 is provided with differential pressure pickup a9; Described reverse stabilising arrangement 7 links to each other with outlet conduit 6.
On the pipeline between flow pattern collating unit 2 and the precession vortex flowmeter 5, also be provided with temperature sensor 3 and pressure transducer 4; The inverted U pipe is provided with differential pressure pickup b12.
The course of work of the present utility model is: fluid is earlier through the flow pattern collating unit, most of gas is told, measured through the precession vortex flowmeter, liquid and small part gas are surveyed gas, liquor ratio through the inverted U pipe, mix through static mixer, it is total to survey total flow Q through Venturi tube again.So just obtained the calculating parameter of needed necessity.Can calculate tolerance and liquid measure by certain formula then.
