Abstract
The utility model discloses a cover tubular construction of water layer in middle of utilizing among geothermol power exploratory well, including being responsible for the body and locating the looped pipeline on the main pipe inner wall, main pipe inner wall is equipped with the recess, can be at the recess internal rotation in the looped pipeline embedded Groove, be equipped with the hole that leaks that is the matrix arrangement on the pipe wall at person in charge's body recess position, be equipped with the through -hole that corresponds with the hole hole site that leaks on the looped pipeline, it is responsible for external side for tubaeform and osculum orientation to leak the hole. The utility model discloses simple structure, design benefit, the water in can the rational utilization stratum supplyes the well drilling water, and the water resource of having saved ground has reduced the probing cost.
Description
Technical field
This utility model is related to geothermal energy resources production technique apparatus field, in utilizing in a kind of underground heat prospect pit
Between water layer sleeve structure.
Background technology
Geothermal energy is the natural heat energy being extracted by the earth's crust, and this energy is derived from the lava of earth interior, and with heating power form
Exist.Geothermal energy is a kind of new clear energy sources, day by day strengthens the feelings increasingly in short supply with the energy in the environmental consciousness of current people
Under condition, the rational exploitation and utilization of geothermal energy resources is more and more favored by people.During geothermal exploration, geology prospect pit
That generally beats is deep, and prospect pit commonly passes through multi-layered aquifer, and some of which water-bearing layer is crushed stone, subsoil water therein
Can be used for drilling work, but current prospect pit sleeve structure cannot realize the utilization of this part subsoil water many.
Utility model content
This utility model is in order to make up the deficiencies in the prior art, there is provided can utilize middle aqueous layer in a kind of underground heat prospect pit
Sleeve structure, this utility model can optionally utilize the subsoil water of suitable water layer in drilling process.
For achieving the above object, this utility model adopts following technical proposals：Can be using middle water in a kind of underground heat prospect pit
The sleeve structure of layer, the looped pipeline including main pipe and on main pipe's inwall, described main pipe's inwall is provided with groove, described pair
The embedded groove of pipe is interior and can rotate in groove, and the tube wall at described main pipe's groove position is provided with leak arranged in arrays
Hole, described looped pipeline is provided with through hole corresponding with leaking hole hole position, and described leaking hole is that tubaeform and osculum is external towards supervisor
Side.
The inwall of described looped pipeline is provided with one group for the draw-in groove with external tool cooperation.
Described leaking hole arranged in arrays, the interval between each column is more than the diameter of through hole on looped pipeline.
During use, main pipe is positioned over utilizable water-bearing layer position, leaking hole from main pipe for the water and looped pipeline
On through hole flow in drilling well；When being no longer necessary to using this part water, with the draw-in groove that instrument snaps in looped pipeline, looped pipeline is rotated one
Determine angle to block leaking hole.
The beneficial effects of the utility model are：This utility model structure is simple, design is ingenious, can rationally utilize in stratum
Water carry out off set drilling water, save the water resource on ground, reduce drilling cost.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is main pipe and the schematic diagram of looped pipeline fit structure.
Wherein 1, main pipe, 2, looped pipeline, 3, leaking hole, 4, draw-in groove, 5, through hole.
Specific embodiment
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before not paying creative labor
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
The sleeve structure of middle aqueous layer can be utilized, including main pipe 1 He in a kind of underground heat prospect pit as shown in Fig. 1 to Fig. 2
Looped pipeline 2 on main pipe 1 inwall, described main pipe 1 inwall is provided with groove, and described looped pipeline 2 embeds in groove and can be recessed
Rotate in groove, the tube wall at described main pipe 1 groove position is provided with leaking hole 3 arranged in arrays, described looped pipeline 2 be provided with
The corresponding through hole of leaking hole 3 hole position 5, described leaking hole 3 is tubaeform and osculum towards outside main pipe 1.
The inwall of described looped pipeline 2 is provided with one group for the draw-in groove 4 with external tool cooperation.
Interval between described leaking hole 3 each column arranged in arrays is more than the diameter of through hole 5 on looped pipeline 2.
During use, main pipe 1 is positioned over utilizable water-bearing layer position, leaking hole 3 from main pipe 1 for the water and pair
Through hole 5 on pipe 2 flows in drilling well；When being no longer necessary to using this part water, snap in the draw-in groove 4 of looped pipeline 2 by looped pipeline 2 with instrument
Turn an angle and leaking hole 3 is blocked.
Although the above-mentioned accompanying drawing that combines is described to specific embodiment of the present utility model, not new to this practicality
The restriction of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel do not need to pay the various modifications that creative work can make or deformation still in protection model of the present utility model
Within enclosing.
