Description
Technical field
The present invention relates to a kind of for the steam of uphole steam generator outlet or ground feed-line during heavy crude heat extraction
Flow regulator.
Background technique
Viscous crude generallys use the mode of heating exploitation due to the characteristics of its viscosity is high, poor fluidity.Steam drive oil production is one
The method of the important heating exploitation viscous crude of kind, it is the steam for continuously injecting high mass dryness fraction into oil reservoir from injection well, is steamed
Vapour constantly heated oil reservoir and substantially reduce the viscosity of in-place oil, the steam of injection becomes the fluid of heat in bottom, will be former
Oil is driven to around producing well, thus by adopting onto ground.Steam drive oil production is heavy crude reservoir by steam oil production
Later, the thermal process taken to further increase recovery ratio, still, steam drives scene often in the presence of a pot at present
The phenomenon that furnace using single pump is simultaneously entire steam injection pipe network steam supply to 2 ~ 3 mouthfuls of well steam injections or multistation injection boiler furnace lacks on pipeline
Steam quantity regulating device limits oilfield exploitation so that the distribution of steam injection amount often has deviation.
To solve the above-mentioned problems, the Chinese invention patent that Authorization Notice No. is CN105626020B discloses a kind of adjustable
Formula steam flow control, the adjustable steam volume control device include movable float (i.e. choked flow core), critical flow spray
Mouth (i.e. sliding sleeve) and transmission device.Wherein, critical flow nozzle is enclosed in steam inside pipe wall, and movable float is located at critical flow spray
The center of mouth, front end are connected with transmission device, and rear end is connected with limit spring, is arranged inside limit spring and steam pipe
After-poppet connection, forms annular space formula runner between critical flow nozzle and movable float；Transmission device includes being arranged in steam pipe
The other end and the steam pipe inside of horizontal conveyor gear shaft that is internal and connecting with movable float, horizontal conveyor gear shaft are arranged
Fore-stock connection, transmission device further includes the tube wall that one end passes through steam pipe, and the other end engages biography with horizontal conveyor gear shaft
Dynamic vertical-transmission gear shaft.The adjustable steam volume control device passes through horizontal conveyor gear shaft and vertical-transmission gear shaft
Engaged transmission drive movable float to move axially and then change the area of passage of annular space formula runner to realize steam flow control
System, still, the adjustable steam volume control device is when adjusting steam flow, since horizontal conveyor gear shaft is with fore-stock
It is flexibly connected, and limit spring is withstood in movable float one end, can not well limit horizontal conveyor gear shaft, easily sends out
Unboiled water is flated pass movable gear shaft offset, and horizontal conveyor gear shaft once shifts and will lead to it with vertical-transmission gear shaft not
The intact engagement of energy, causes transmission device that movable float cannot be driven to act, and then steam flow is caused to be unable to get effective tune
Section.
