Description
Technical field
The present invention relates to gas production field, down-hole, specifically refer to aqueous vapor well draw-out device.
Background technology
All ponding can be there is in shaft bottom in various degree at home in most gas well, for the gas well that there is end water or limit water, in recovery process, liquid-gas ratio will increase gradually, if adjustment liquid-gas ratio or shaft bottom hydrops get rid of well head not in time not in time, this can cause the normal production of gas well, even that gas well is drowned and cause stopping production, therefore the jacking capacity of correct Prediction gas well under liquid content in various degree selects the water drainage-gas recovery technology of suitable gas well to have important practical significance according to the actual conditions of gas well.
Liquid when gas well shaft bottom has just started to occur a small amount of hydrops in pit shaft can be utilized the climbing power of self to take pit shaft out of by gas, gas well can also normally be produced, at this moment the most stream flow velocity of gas well air-flow is called that liquid critical flow velocity taken by gas well, and corresponding gas flow is called that liquid critical flow taken by gas well; When in pit shaft, the actual flow velocity of gas is less than critical flow velocity, liquid in well just can not utilize the climbing power of self to take well head out of by air-flow.And in prior art, usual employing emple hole, liquid obtains larger kinetic energy after pressurization, after nozzle, liquid ejects with very large speed, under surface tension of liquid, viscosity and air resistance interact, liquid flows by dripping, smoothly, wave flow changes gradually to spray flow, finally conveniently realizes the two-phase laminated flow of gas-liquid; But because the current of discharging in emple hole have surface tension, therefore become in the process of spray flow at liquid rotating, need constantly could to meet liquid to down-hole pressurization there is when ejecting very high speed to occur to rub with ambient air and be separated atomization, then the air pressure of down-hole is higher, the safety reliability faced during gas production is lower, very easily causes security incident.
Summary of the invention
The object of the present invention is to provide aqueous vapor well draw-out device, facilitate gas-liquid independently to rise fast and discharge outside well, reach the object improving gas production safety reliability simultaneously.
Object of the present invention is achieved through the following technical solutions:
Aqueous vapor well draw-out device, comprise and be fixed on packer in sleeve pipe and stationary magazine creel, the cavity that prestores is connected with in turn in the upper end of described sleeve pipe, steam-water separator and pond, described stationary magazine creel has been threaded nozzle, the nozzle housing that described nozzle comprises nozzle inner core and is set in outside nozzle inner core, the end of nozzle housing is provided with spurt hole, in described nozzle inner core one end, internal conical surface is set, and the inwall of described internal conical surface and nozzle housing forms air inlet cavity, the nozzle inner core other end has just to the through hole of spurt hole, through-hole wall is provided with multiple swirl vane, and the inwall of through hole and nozzle inner core forms eddy flow cavity.To having in the recovery process of gas well of certain water content, sleeve pipe is placed in the gas-bearing formation at the end, ground, by packer, sleeve upper end and its lower end are completely cut off, in gas well, injection pressure promotion packer is opened and sleeve pipe upper and lower side is communicated with, and stationary magazine creel is installed nozzle, then spurt into by nozzle the cavity that prestores in the compressing of pressure interior gas-fluid two-phase mixture of going into the well, and prestore cavity and steam-water separator, pond connects successively, namely gas-liquid mixture is directly carried out the separation of gas-liquid two-phase after being injected into by nozzle the cavity that prestores by steam-water separator, isolated gas is discharged to the gathering-devices such as gasholder, isolated moisture then drains in pond,
