Description
Technical field
The present invention relates to coal seam reservoirs release extinction, Coal-seam Gas Recovery Technologies fields, and in particular to a kind of circulating wire cutting
The coal mine release extinction of micro- Protective Coal Seam and coal-bed gas exploitation system and method, the single coal seam reservoirs larger especially suitable for thickness
Gas control.
Background technology
China major part mining area deformation coal comparative development, the coal seam in region is with coal quality is soft, gas permeability of coal seam is poor, high
The features such as gas bearing capacity, the gas control and coal-bed gas exploitation of single thicker coal seam reservoirs become generally acknowledged global problem.At present
China's gas control and coal-bed gas exploitation form different production techniques for different coal seam reservoirs.For primary structure coal, ooze
When rate is higher thoroughly, ground extraction mode is mainly used；And it is directed to multiple seam, mostly use underground extraction after exploiting protective layer release
Mode, wherein being combined after adopting before adopting, in adopting；For the smaller single construction coal of coal seam thickness, after underground fracture
The modes such as extraction or the direct extraction of down-hole drilling；For single " three the is soft " coal seam that coal seam thickness is larger, the lanes Di Chou are mostly used
Extraction after punching release.
In short, current gas control includes mainly following two means with Coal-seam Gas Recovery Technologies：First, reducing reservoir pressure
Power causes desorption of mash gas, seepage flow output under the action of pressure difference, as ground drilling drainage and step-down gas producing technology and down-hole drilling are negative
Pressure draws out methane technology, but tradition from the straight well of ground extraction gas and horizontal well Coal Quality is soft, hypotonic and high methane
Region cannot effectively large area distressing mining it is anti-reflection；The other is by disturbing original pressure-bearing coal seam, manufacture stress release space makes
Coal mesoporous crack increases on a large scale, reduces adsorption gas pressure-bearing fast desorption, while expanding gas porous flow output channel, such as protects
Pressure-relief outburst-prevention measure in the layer layer such as production technique and hydraulic loose.Protective coat extracted technology be most effective region protrusion-dispelling technology it
One, but it is limited by geological conditions, is generally used for the mine of coal seam group mining, and it is larger to single coal bed and interlamellar spacing
Coal seam is not suitable for hydraulic loose, though hydraulic loose is the antireflective outburst prevention measures of release in a kind of layer, is played in hyposmosis coal body
Certain effect, but in the process of implementation, often there is gas exceeding limits frequently, easily causes the problems such as human-induced protrudes, no
It can carry out regional release.
Particular for the single coal seam reservoirs that thickness is larger, current coal seam reservoirs release extinction technology and Coal-seam Gas Recovery Technologies
Good effect is not obtained, while with the increase of coal seam buried depth, for the technology of gas control and coal-bed gas exploitation
Difficulty is increasing, and the ton coal treatment cost of coal-bed gas exploitation enterprise continues to increase, there is an urgent need for find low cost, can scale, from
The gas control and coal bed methane exploring method of dynamicization.
