Description
Technical field
The utility model relates to gas production field, down-hole, specifically refers to a kind of down-hole gas production vortex atomizing nozzle.
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 drag 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 surrounding 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.
