Abstract
The utility model discloses a gas well spiral-flow type booster which comprises a connector, a middle cavity and a threaded cavity. The upper end of the middle cavity is connected with the connector, the lower end of the middle cavity is connected with an outer cavity, the threaded cavity is of a hollow structure, a spiral line is arranged on the threaded cavity, and the hollow structure and the inner wall of the middle cavity form a California tube type. The gas well spiral-flow type booster uses oil gas well shaft bottom energy as kinetic energy to change gas-liquid phase-free flow in a shaft into spiral-flow phase flow so as to increase gas-liquid flow speed and achieve water drainage and gas extraction purposes. The gas well spiral-flow type booster has the advantages of being simple in structure, strong in adaptability and good in water drainage and gas extraction effects.
Description
Technical field
The utility model relates to a kind of oil gas well downhole hardware, is specifically related to a kind of gas well spiral-flow type booster.
Background technology
In the gas well recovery process, because moisture rising makes simple gas form gas liquid mixture gradually, downhole fluid density increases, and the lifting difficulty increases, and greatly has influence on the gas extraction effect.In high oil-gas ratio oil mining process, a large amount of solution gas in the crude oil very easily forms slippage effect, for the deep-well pump sump, will produce the gas blowout phenomenon, and pump efficiency is reduced, and causes oil gas well cost of production to raise.The problems referred to above are main at present to adopt gas anchor that the gas in the oil is broken away from, but it also exists: 1. for the bigger oil well of gas content, effect is undesirable; 2. gas anchor length is bigger, and the installation site is more fixing, is unfavorable for exhaust; 3. for gas recovery well, gas anchor does not possess the function of dehydration gas production, thereby the application of incompatibility gas recovery well.
The utility model content
To the problems referred to above, the utility model provides a kind of novel gas well spiral-flow type booster, has effectively improved gas production efficient.
The technical scheme that the utility model adopts is:
A kind of gas well spiral-flow type booster comprises joint, intermediate cavity, thread cavity, it is characterized in that: said intermediate cavity upper end links to each other with top connection; The lower end is connected with thread cavity; Said thread cavity is a hollow-core construction, which is provided with helix, and its hollow and said intermediate cavity inwall forms markon's form of tubes.Said thread cavity is provided with and the hollow screw gas port that is communicated with.Said thread cavity one end is connected with intermediate cavity, and the other end links to each other with lower contact.Said thread cavity wall is provided with the thread cavity outage.
Compared with prior art, the advantage of the utility model is:
The utility model gas well spiral-flow type booster utilizes oil gas well shaft bottom energy to be kinetic energy, and not having the phase rheology to vapour-liquid in the pit shaft is that spiral-flow type has stream mutually, thereby has increased the vapour-liquid flow velocity, reaches the purpose of water pumping gas production.Have simple in structure, easy to use, with low cost, characteristics such as compliance is strong, and water pumping gas production is effective.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further explained.
A kind of gas well spiral-flow type booster as shown in Figure 1; Comprise top connection 1, intermediate cavity 2, thread cavity 4; Said intermediate cavity 2 upper ends link to each other with top connection 1, and the lower end is connected with thread cavity 4, and said thread cavity 4 is a hollow-core construction; Which is provided with helix 3, its hollow and said intermediate cavity 2 inwalls form markon's form of tubes.Said thread cavity 4 is provided with and the hollow screw gas port that is communicated with.Said thread cavity 4 one ends are connected with intermediate cavity 2, and the other end links to each other with lower contact 7.Said thread cavity wall is provided with the thread cavity outage.
The operating principle of the utility model: gas well spiral-flow type booster utilizes oil gas well shaft bottom energy to be kinetic energy, and not having the phase rheology to vapour-liquid in the pit shaft is that spiral-flow type has stream mutually, thereby has increased the vapour-liquid flow velocity, reaches the purpose of water pumping gas production.Have characteristics such as simple in structure, that compliance is strong, and water pumping gas production is effective.
Though the utility model is described with reference to aforesaid specific embodiment; But those skilled in the art will be appreciated that; Above embodiment only is in order to explanation the utility model rather than restriction the utility model, as long as in the scope of in the connotation scope of the utility model, the variation of the foregoing description, claims that modification all should fall into the application being asked for protection.
