Description
Technical field
This utility model is related to a kind of coal-bed gas gas extraction technology, particularly a kind of quick pocket type filtering pressure hole sealing device.
Background technology
Coal-bed gas are a kind of clear energy sources, but a kind of disaster source is even more for coal production.Therefore, gassy
Gas pumping must be carried out before seam mining because the coal hosting geological condition of China is complicated, the soft degree in coal seam, buried depth etc.
Difference, relies primarily at present underground mining.Existing coal-face gas pumping be respectively by transportation roadway and return airway
Concordant drilling is played in this coal seam carries out extraction, and the coal seam poor for breathability generally need to also be after hydraulic fracturing anti-reflection be carried out again
Row extraction.Coal bed gas extraction is carried out by gas drainage system by numerous drainage holes, anti-reflection and by pressure break even for pressure break
Used as the coal seam of drainage holes, it only also takes up the overwhelming majority as the way drainage holes of extraction in hole.Drainage holes drilling, insert take out
To adopt needed after pipe and carry out sealing pores, to prevent gas leakage.The method for sealing of existing drainage holes is more, and most common method is
Injection hole sealing method, the method, in sealing of hole sections slip casting, has certain bearing capacity by Grouting Pipe to be formed after slurry curing
Sealing of hole sections.Because the bearing requirements of extraction sealing of hole are relatively low compared with the bearing requirements of pressure break sealing of hole, adopt and filtering pressure bag is noted
The mode of slurry is by the method for sealing Jing that sealing of hole sections are formed between the filtering pressure bag filled with slurry and borehole wall and extraction pipe outer wall
Ji is practical.The device of the method includes filtering pressure bag and Grouting Pipe, and the most economical is that Grouting Pipe adopts flexible pipe, but prior art
In Grouting Pipe can not be unloaded from filtering pressure bag after slip casting, cause the Grouting Pipe after sealing of hole to be wasted.And for need envelope
Cross relaxation zone affect or deeper coal seam extraction borehole, due to sealing of hole sections away from orifice distance farther out, this wasting phenomenon is particularly bright
It is aobvious.For this reason, it may be necessary to be improved to existing hole sealing device and method.
The content of the invention
The purpose of this utility model is for the deficiencies in the prior art, there is provided a kind of quick filtering pressure hole sealing device, the sealing of hole
