Abstract
The utility model discloses an allotter of dryness fraction of boiler steam used in heavy crude thermal production. The allotter comprises an inlet main pipe line, an upper branch outlet pipe line and a lower branch outlet pipe line. An upper triplet 2 and a lower triplet 3 are sequentially connected to the inlet main pipe line 1. The upper triplet 2, an upper valve 4, an upper bend 5 and an outlet pipe line 7 are sequentially connected. The lower triplet 3, a lower valve 8, a lower bend 9 and the upper branch pipe line 7 are sequentially connected. The inner wall of the outlet pipe line 7 is provided with a pore plate 6. A main pipe line 10, a master valve 11, a lower branch pipe line 12 are sequentially connected. The allotter of dryness fraction of boiler steam is simple in structure, convenient in installment, and can realize the arbitrary adjustment of flow quantity and dryness of each branch line, thereby the same dryness of injected steam of the two oil-wells is achieved, the operation is reliable and the production costs is low.
Description
The utility model relates to a kind of heavy crude heat extraction with mass dryness fraction distributors such as Boiler Steam.
In petroleum industry, viscous crude is difficult to exploitation owing to viscosity is high, therefore need be from ground to the stratum steam in jection, utilize steam soak or steam flooding technology crude oil extraction, steam quality is the primary factor that influences steam soak and steam flooding effect.Now boiler steam in jections simultaneously in many mouthfuls of oil wells that adopt require that steam quality must be identical in each branch line more.Now the oil field commonly used etc. the mass dryness fraction distributor be mass dryness fraction distributors such as ball-type, large-sized pressure vessel is installed, complex structure can't be realized any adjusting of each linear flow rate, mass dryness fraction; And mass dryness fraction distributor such as ball-type belongs to the emission type distributor, its operating principle is to make steam portion's mixing within it, the vapor stream of mass dryness fraction such as isolate again, because the injection pressure of stream-liquid two-phase flow self character and each mouthful well is not quite similar, so can not realize fully from flow pattern, flow velocity and a pipeline section flow symmetry of the isolated stream-liquid two-phase flows of mass dryness fraction distributor such as ball-type, so just can not realize that each branch line waits mass dryness fraction to distribute completely.
The purpose of this utility model provides a kind of mass dryness fraction distributors such as Boiler Steam simple in structure, can be implemented under any injection pressure by this distributor, regulates flow, realizes the balanced fully distribution of each branch line steam quality.
The purpose of mass dryness fraction distributors such as Boiler Steam of the present utility model is to realize like this, it comprises female pipeline of import and upper and lower branch outlet pipeline, be connected with threeway and following threeway in turn on the female pipeline of import, last threeway, last valve, last elbow, outlet line connect successively, following threeway, lower valve, following elbow, top set's outlet line connect successively, and the outlet line inwall is provided with orifice plate; Trunk Line, total valve, inferior division pipeline connect successively.
Mass dryness fraction distributors such as the utility model Boiler Steam are equipped with tee piece, can distribute the stream-liquid two-phase flow body of different flow and mass dryness fraction, can realize any adjusting of each linear flow rate, mass dryness fraction by pipeline valve and orifice plate, thereby realize that two mouthfuls of oil well steam in jection mass dryness fractions are identical.This steam quality distributor does not contain large-sized pressure vessel, and is simple in structure, easy for installation, and reliable operation is cheap.
Below in conjunction with accompanying drawing the utility model is described further.
Accompanying drawing 1 is a structure chart of the present utility model.
As shown in Figure 1, mass dryness fraction distributors such as Boiler Steam of the present utility model comprise the female pipeline 1 of an import and upper and lower two branch outlet pipelines, be connected with threeway 2 and following threeway 3 in turn on the female pipeline 1 of import, last threeway 2, last valve 4, last elbow 5, outlet line 7 connect successively, following threeway 3, lower valve 8, following elbow 9, outlet line 7 connect successively, and outlet line 7 inwalls are provided with orifice plate 6; Trunk Line (10), total valve 11, inferior division pipeline 12 connect successively.Upper and lower two take-off line outlet lines lead to two mouthfuls of oil wells respectively.Outlet line 7 inwalls are provided with orifice plate (6), and this orifice plate can make by the steam pressure in elbow 5 and the elbow 9 and equate.
During steam injection, steam the mass dryness fraction distributor such as enters from the female pipe 1 of import, by last threeway 2 and following threeway 3, distributes the stream-liquid two-phase flow body of two strands of different flows and mass dryness fraction respectively.Because phase separation, steam quality in last threeway 2 pipelines is higher than the steam quality in the Trunk Line, and the steam quality in following threeway 3 pipelines is less than the steam quality in the Trunk Line 9, can be installed in the ratio that valve 4 on top set's outlet line and valve 8 are regulated high-quality steam and low mass dryness fraction steam this moment by adjusting, steam quality about so just can making in the branch outlet pipeline is identical, thereby realizes that two mouthfuls of oil well steam in jection mass dryness fractions are identical.
