Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in FIG. 1 to FIG. 2, a kind of device of exploiting coal bed methane, including forcing pipe 1, exhaust tube 2, the first air bag 3,
Two air bags 4, compressed air source unit 9, the forcing pipe 1 and exhaust tube 2 are arranged parallel, and the setting of the first air bag 3 is in forcing pipe 1 and takes out
On tracheae 2, second air bag 4 is arranged on forcing pipe 1, and the pumping air inlet 7 of described 1 one end of forcing pipe is located at the first air bag
3 and second between air bag 4, and the pumping gas outlet 8 of 1 other end of forcing pipe is located at the outside of the first air bag 3, is located at the first gas
Pressurization gas outlet 5 is opened up on forcing pipe 1 inside capsule 3, and pressurization gas outlet is opened up on the forcing pipe 1 inside the second air bag 4
5, silk plug 6, the end of 1 other side of forcing pipe and compressed air source unit is arranged in the end positioned at the forcing pipe 1 in 4 outside of the second air bag
9 are connected.
Preferably, first air bag 3 and the second air bag 4 are that acrylic rubber is made.
Preferably, first air bag 3 and the second air bag 4 are that hydrogenated nitrile-butadiene rubber is made.
Preferably, the gas that the compressed air source unit 9 provides is nitrogen.
Preferably, the gas that the compressed air source unit 9 provides is carbon dioxide.
The use operating method of the utility model:
When utility model works with coal bed gas pumping gas collecting equipment be used cooperatively, by the pumping gas outlet 8 of forcing pipe 1 with
It is evacuated the air inlet pipeline connection of gas collecting equipment.
One end forcing pipe 1 and exhaust tube 2 that are provided with the first air bag 3 and the second air bag 4 are put into coal bed gas well, make the
One air bag 3 and the second air bag 4 are placed in coal seam 10 section position of the coal bed gas compared with enrichment.
It, can be smooth since before use, the 4 inside unaerated of the first air bag 3 and the second air bag, respective volume retraction is smaller
It is put into coal bed gas well.
Start compressed air source unit 9, high pressure nitrogen or high-pressure carbon dioxide gas are imported the by forcing pipe 1 by compressed air source unit 9
Inside one air bag 3 and the second air bag 4.
Because the end of forcing pipe 1 is provided with silk plug 6, gas cannot be discharged from end, the gas released from compressed air source unit 9
Body, pressurized pipe 1 are discharged from the pressurization gas outlet 5 inside the first air bag 3 and the second air bag 4 respectively, and gas respectively enters
Inside one air bag 3 and the second air bag 4, by compression swelling, the first air bag 3 and the second air bag 4 inside the first air bag 3 and the second air bag 4
Outer wall and coal bed gas well 10 inner wall of coal seam be in close contact.Coal bed gas well section between first air bag 3 and the second air bag 4 at
For sealing space, start the coal bed gas pumping gas collecting equipment being used cooperatively, the coal between the first air bag 3 and the second air bag 4 at this time
The gas of layer gas well section is gone out by strong pumping, into coal bed gas collecting.This coal-bed gas exploitation aspirates more added with needle
To property, production effect concentration is acted on into coal seam 10 section of the coal bed gas compared with enrichment, lesser suction exploitation can consume energy generate compared with
Big output, production efficiency and benefit are higher.
It is very safe in production, and this kind of gas since the high pressure gas that compressed air source unit 9 provides is nitrogen or carbon dioxide
Source is easy to produce to obtain, lower production costs.
Acrylic rubber and hydrogenated nitrile-butadiene rubber have many advantages, such as high-intensitive, wear-resisting, heat-resisting, ageing-resistant, oil resistant etc., power
Better performances are learned, can apply to various high temperature, in resistance to oil environment, using effect is more preferable.
