Abstract
The utility model relates to a flow string pillar device mounted with an electric vortex heating pipe. A heating device is connected to a flow string pillar of an oil well. The utility model is characterized in that an electric vortex heating pipe (2) is arranged at the middle position of the flow string pillar (1); the upper end and the lower end of the electric vortex heating pipe (2) are respectively connected with the flow string pillar (1) through screws.
Description
Affiliated technical field
The utility model relates to a kind of flow string device that the current vortex heating tube is housed, and it is that heater is set in flow string.
Background technology
At present, known flow string heater is an electric heating rod, defectives such as fragile, difficult reparation that electric heating rod has.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of flow string device that the current vortex heating tube is housed, and this device substitutes the heating crude oil that electric heating rod is given the flow string inner chamber with the current vortex heating tube, and this device is not fragile, easily repairs.
The technical scheme that its technical problem that solves the utility model adopts is: be provided with current vortex heating tube [2] in the middle part of flow string [1], the connected mode of its top and bottom and flow string [1] is screwed connection.Fluid heating by current vortex heating tube [2] is given flow string [1] inner chamber can effectively reduce viscosity of crude, prevent oil well paraffinication.
The beneficial effects of the utility model: by field trial, the utility model compared with prior art, this device efficiency of heating surface height, not fragile, maintenance easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
(accompanying drawing) a kind of structure embodiment schematic diagram that the flow string device of current vortex heating tube is housed.1. flow strings, 2. current vortex heating tubes, 3. oil extraction pumps, 4. sleeve pipes, 5. screen casings, 6. plugs among the figure
The specific embodiment
In the accompanying drawings, flow string [1], current vortex heating tube [2], oil extraction pump [3], screen casing [5], plug [6] are cascaded.The crude oil on stratum through screen casing [5], oil extraction pump [3], current vortex heating tube [2], flow string [1], flow to ground, crude oil is heated when flowing through the inner chamber of current vortex heating tube [2], thereby the temperature of crude oil is raise, viscosity reduces, by changing the frequency of power supply, the temperature of regulating flow string [1] internal flow.Adopt this device can effectively prevent oil well paraffinication, reduce the oil extraction cost.
Claims (1)
- A kind of flow string device that the current vortex heating tube is housed, in the flow string of oil well, connect heater, it is characterized in that: in the middle part of flow string [1] current vortex heating tube [2] is set, the top and bottom of current vortex heating tube [2] respectively with flow string [1] by screwed connection.
