Description
Technical field
The invention belongs to coal-bed gas exploitation field, more particularly to a kind of static expanding agent injected system and method for implanting.
Background technology
According to China《Prevent and treat coal and gas prominent regulation》, outburst prevention measures main at present are to take out coal seam in advance, and coal seam is taken out in advance
The extracting result of gas depends primarily on the Permeability Coefficent in Coal Seam, and low permeability outburst coal seam gas pumping technology has extraction
Cycle is long, and cost is high, and extraction concentration is low, the low technical problem of extraction efficiency.Solve low-permeability coal seam extraction problem is to increase at all
Plus gas permeability of coal seam, current existing hydraulic fracturing anti-reflection, high energy gas is anti-reflection, deep hole blasting is anti-reflection, drilling, slot is anti-reflection technology
It is limited Deng the technical method scope of application, it is difficult to large-scale promotion application.Hydraulic fracturing anti-reflection complex process, water under high pressure easily causes coal
The secondary pollution of layer, pressure break is anti-reflection, and the time is relatively long.It is poor to the extremely soft seam adaptability of easy collapse hole that high energy gas is anti-reflection.
Complex process that deep hole blasting is anti-reflection, financial cost is higher, requires higher to one-tenth porosity and hole quality, there is blown-out shot, spark etc.
Latent dangerous factor.Drill, slot is anti-reflection, and the anti-reflection scope of technology is smaller, antireflective effect, typically buried high stress coal seam is fitted
It is poor with property.
The content of the invention：The technical problem to be solved in the present invention is：A kind of static expanding agent injected system and injection side are provided
Method, to solve prior art to the anti-reflection technical method complex process of low permeability outburst coal seam, cost is higher, and effect is paid no attention to
Want there is certain risk, applicability is poor, it is difficult to the technical problem such as large-scale promotion application.
Technical solution of the present invention：
A kind of static expanding agent injected system, it includes agitating device, and agitating device bottom passes through drainpipe and four-way connecting tube
Connection；Four-way connecting tube is connected by connecting tube with hard drainpipe；Hard drainpipe is located in drilling.
Valve, flow valve and compression pump are sequentially set with drainpipe.
Drainpipe is flexible water drainage pipe.
A kind of static expanding agent method for implanting, it includes：
Step 1, the agitating device that water, static expanding agent and delay medicament are added into static expanding agent injected system in proportion are stirred
Mix uniform；
Step 2, by compression pump the swelling agent stirred is injected in coal seam by the pipeline that is preset in coal bed drilling.
Beneficial effects of the present invention：
The present invention injects the static expanding agent stirred in coal seam, and swelling agent is produced newly in coal bed drilling swelling cracking
Crack, increases Permeability Coefficent in Coal Seam, beneficial to the exploitation of coal bed gas, improves gas pumping rate；The present invention is simple in construction, detachably
Carry, it is reusable, it is with low cost；It is easy to promote the use of；Prior art is solved to the anti-reflection skill of low permeability outburst coal seam
Art method complex process, cost is higher, and effect is undesirable, there is certain risk, and applicability is poor, it is difficult to large-scale promotion
Using etc. technical problem.

Agitating device 1 uses static expanding agent agitating device.
Valve 2, flow valve 4 and compression pump 5 are sequentially set with drainpipe 3.The effect of valve 2 is easy for opening and closing
The conveying of swelling agent；The effect of flow valve 4 is easy for the volume of the swelling agent in operating personnel's observation injection hole；Compression pump 5
Effect be increase pressure, improve swelling agent injection hole efficiency；Compression pump 5 can access the swelling agent of multichannel drainpipe simultaneously
Output, increases injection efficiency.
Drainpipe 3 is flexible water drainage pipe；The purpose of flexible water drainage pipe is selected, is on the one hand easy for carrying and loads and unloads；The opposing party
Face is to reduce floor space.
A kind of static expanding agent method for implanting, it includes：
Step 1, the agitating device 1 that water, static expanding agent and delay medicament are added to static expanding agent injected system in proportion
Stir；
Step 2, by compression pump the swelling agent stirred is injected in coal seam by the pipeline that is preset in coal bed drilling.
According to coal bed drilling volume, it is determined that the raw material proportioning such as required water, static expanding agent, delay medicament, puts into static state
In swelling agent agitating device；
Static expanding agent agitating device bottom connecting pipe, static expanding agent is stirred by being preset in coal by compression pump handle
In pipeline injection coal seam in layer drilling；
Static expanding agent injected system can meet multiple drillings and inject simultaneously.
