Method is monitored in real time come the steam data to each branch line, but existing steam monitoring and metering system is low there are measuring accuracy
Problem.
The moist steam or dry saturated steam fed distance in steam injection pipe network generated due to injection boiler is longer, with heat under stable state
The loss mass dryness fraction decline of amount is also easy to produce vapour-liquid lamination.Steam quality meeting when being assigned to branch line by distributor or collection vapour device again
Occur bias phenomenon, be not achieved each branch line etc. mass dryness fractions distribution requirement.
Utility model content：
The technical problem to be solved by the present invention is to provide the mass dryness fractions such as a kind of uphole steam generator steam multistage mixed phase point
With device, the arrangement achieves the mass dryness fractions such as the steam in main line are evenly dispersed into each branch line, it can realize that each branch line steams
Vapour mass dryness fraction is identical, can carry out the parameter real time monitorings such as flow, mass dryness fraction, pressure, temperature, measuring accuracy to the steam for entering oil well
Height makes each well location of thermal recovery well location close quarters realize the science steam injection of the mass dryness fractions such as steam distribution.Overcome existing steam injection pot
The steam that stove generates such as is not achieved when being assigned to each branch line at mass dryness fractions distribution requirement, while the deficiency that each branch line measuring accuracy is low.
Technical solution adopted in the utility model is：A kind of mass dryness fractions such as uphole steam generator steam multistage mixed phase distribution dress
It puts, including main process pipeline and multiple branch lines；Shut-off valve I and even phase device, main process duct are set gradually on main process pipeline
The mass dryness fractions spherical distributor such as way outlet end and steam is connected, and the mass dryness fractions such as steam spherical distributor is connected with multiple branch lines
It connects, regulating valve, pressure transmitter, taper orifice flowmeter, thermocouple, check valve and cut-off is set gradually on each branch line
The mass dryness fractions spherical distributor bottom end such as valve II, steam connects blowoff line by shut-off valve III, and each branch line passes through cut-off respectively
Valve IV is connected with blowoff line.
The beneficial effects of the utility model are：The utility model, which realizes, is uniformly dispersed the mass dryness fractions such as the steam in main line
To each branch line, can realize that each branch line steam quality is identical, can to enter oil well steam carry out flow, mass dryness fraction, pressure,
The parameter real time monitorings such as temperature, measuring accuracy is high, and each well location of thermal recovery well location close quarters is made to realize the distribution of the mass dryness fractions such as steam
Science steam injection.
Description of the drawings：
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structure diagram of the utility model.
Specific embodiment：
As shown in Figure 1, a kind of mass dryness fractions distributor such as uphole steam generator steam multistage mixed phase, including main process pipeline 12
With multiple branch lines 13；Set gradually shut-off valve I 1 and even phase device 2 on main process pipeline 12, main 12 port of export of process pipeline with
The mass dryness fractions such as steam spherical distributor 3 is connected, and the mass dryness fractions such as steam spherical distributor 3 is connected with multiple branch lines 13, each
Regulating valve 4, pressure transmitter 5, taper orifice flowmeter 6, thermocouple 7, check valve 8 and cut-off are set gradually on branch line 13
3 bottom end of the mass dryness fractions such as valve II 9, steam spherical distributor connects blowoff line 14 by shut-off valve III 10, and each branch line 13 is distinguished
It is connected by shut-off valve IV 11 with blowoff line 14.
The utility model is using multistage mixed phase technology：Level-one mixed phase is on 3 entrance pipeline section of the mass dryness fractions such as steam spherical distributor
