Utility model content
The purpose of this utility model is that providing a kind of mid-deep strata interference-free hot well to solve the above-mentioned problems changes
Heat pipe downhole device is gone into the well difficulty with solving traditional heat exchanger tube in the prior art, is easy to be influenced by down-hole liquid buoyancy
The problems such as.Preferred technical solution can eliminate liquid during heat exchanger tube is gone into the well in many technical solutions provided by the utility model
Influence of the body to its buoyancy facilitates heat exchanger tube the technical effects such as quickly to go into the well, elaboration as detailed below.
To achieve the above object, the utility model provides following technical scheme:
A kind of mid-deep strata interference-free hot well heat exchanger tube downhole device provided by the utility model, including it is plugged on geothermal well
Interior casing is provided with heat exchanger tube in described sleeve pipe, and the heat exchanger tube lower end is equipped with downhole device, and the downhole device can band
Move heat pipe rapid decrease in casing.
As the significant design of this case, the downhole device includes metal tube and metal weighted item, and the metal tube is fixed
It is mounted on the lower end of heat exchanger tube, the metal weighted item is fixedly mounted on the lower end of metal tube, the shaft bottom installation of the geothermal well
There is sealing ring, the metal weighted item is inserted into sealing ring.
As the optimization design of this case, the metal weighted item is cone.
As the optimization design of this case, the basal diameter of the metal weighted item is greater than the external world of metal tube.
As the optimization design of this case, multiple through-holes are provided on the tube wall of the metal tube.
As the optimization design of this case, the aperture of the through-hole is not more than 50 millimeters, and is not less than 5 millimeters.
Beneficial effect is: a kind of mid-deep strata interference-free hot well heat exchanger tube downhole device described in the utility model can
Influence of the liquid to its buoyancy during heat exchanger tube is gone into the well is eliminated, facilitates heat exchanger tube quickly to go into the well, practicability is good.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
The reference numerals are as follows:
1, geothermal well；2, heat exchanger tube；3, metal tube；4, through-hole；5, metal weighted item；6, sealing ring；7, casing.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
It is shown in Figure 1, a kind of mid-deep strata interference-free hot well heat exchanger tube downhole device provided by the utility model, including
The casing 7 being plugged in geothermal well 1 is provided with heat exchanger tube 2 in casing 7, and 2 lower end of heat exchanger tube is equipped with downhole device, dress of going into the well
The rapid decrease in casing 7 of heat exchanger tube 2 can be driven by setting.
As optional embodiment, downhole device includes metal tube 3 and metal weighted item 5, and metal tube 3 facilitates metal to add
Heavy mail 5 is fixedly connected with heat exchanger tube 2, and 5 one side of metal weighted item is for dredging casing 7, on the other hand for driving heat exchanger tube 2
The rapid decrease in casing 7, metal tube 3 are fixedly mounted on the lower end of heat exchanger tube 2, and metal weighted item 5 is fixedly mounted on metal tube 3
Lower end, the shaft bottom of geothermal well 1 is equipped with sealing ring 6, and metal weighted item 5 is inserted into sealing ring 6, to reach heat transfer effect
Fruit.
Metal weighted item 5 is cone, and conical design can reduce resistance when liquid declines metal weighted item 5.
The basal diameter of metal weighted item 5 is greater than the external world of metal tube 3, designs in this way, and metal weighted item 5 can play to change
The purpose of the dredging casing 7 of heat pipe 2.
Multiple through-holes 4 are provided on the tube wall of metal tube 3, through-hole 4 facilitates liquid to pass in and out metal tube 3, then by metal tube 3
