Description
Technical field
The invention belongs to the anti-reflection technical fields of coal mine gas enhanced gas extraction, are related to a kind of single channel water-jet punching press pipe nipple
With method.
Background technique
Extraction is the main path of control of coalmine gas, and the technology that the engineering practice of many decades is formed has been able to substantially full
The requirement of the current Safety of Coal Mine Production of foot.Such as standing, hydraulic fracturing, hydraulic slotted liner technique, hydraulic flushing in hole, bore punching integration,
Brill develops the technologies such as integration, these technologies are effectively increased the permeability in coal seam to a certain extent, achieves some effects
Fruit.But will from " be pumped out to be pumped it is fast, be pumped province, be pumped it is complete " conversion, it is also necessary to theoretical is further perfect, technology
Continue innovation and the development of new equipment.Only so, multipath spatially and temporal multistage negotiation can be realized
Space-time extraction.
Hydraulic punching then effectively combines hydraulic flushing technology and hydraulic jetting fracturing technology, takes full advantage of hydraulic flushing in hole
The release that can produce coal is anti-reflection, and hydraulic jetting fracturing technology can be opened, be extended, extending the anti-reflection advantage of cracks in coal seam, and the two respectively takes
The chief has remarkable effect for effectively administering Gas Disaster.But hydraulic punching anti-reflection mash gas extraction is related to drilling, waterpower punching
Hole, hydraulic fracturing need to move back brill, move and bore, then reuse plain tubing or coiled tubing for punching press after Completion of Drilling Hole
Device is sent to pressure break, punching position, activity duration length, large labor intensity.Binary channels is bored punching press integrated apparatus and is avoided with method
Troublesome operation when pressure break or punching is carried out after previous Completion of Drilling Hole, but can also be encountered during use at the scene as follows
Problem: it when (1) boring punching press construction, needs using dedicated binary channels water pigtail, binary channels drilling rod, this needs scene to carry out in advance more
Change the work such as water pigtail, drilling rod and drilling rod aid device；(2) when package unit assembles, adjacent two drilling rods, which are spirally connected, often to be occurred
The poorly sealed problem of internal channel, leads to control device failure；This problem Producing reason has two: first is that, it is interior when drilling rod dispatches from the factory
Passage length is inadequate, so that internal channel does not abut each other after two neighboring drilling rod is spirally connected, and then leaves gap；Second is that drilling rod
After multiple loading, unloading, the sealing rubber ring at the place that is spirally connected is damaged；(3) internal channel needs maintenance in time, prevents coal dust from entering；Above-mentioned three
The presence of a problem bores the field application of punching press integrated apparatus to binary channels and popularization brings great resistance.

The mouth of a river is connected separately with low pressure waterpipe and high-pressure water pipeline by threeway, and low pressure penstock is provided on low pressure waterpipe, high
High pressure water valve and relief valve are provided on pressure pipe road.
6. a kind of single channel water-jet process for stamping using device as claimed in claim 5, which is characterized in that including following
Step:
(1) it assembles single channel water-jet stamping device: passing sequentially through and be threadedly coupled single channel water pigtail, single channel drilling rod, single-pass
Road water-jet punching press pipe nipple and drill bit form single channel water-jet stamping device；
(2) access low pressure water and high pressure water: single channel water pigtail is respectively connected to low pressure water and high pressure water by threeway, and low pressure water is used for
Brill is crept into and moves back, high pressure water is used for punching and pressure break, and low pressure water controls on-off by low pressure penstock, and high pressure water passes through high pressure water
Valve controls on-off, is equipped with relief valve on high-pressure water pipeline；
(3) it creeps into: needing to ensure that high pressure water valve is closed before operation of drilling, open low pressure penstock, low pressure water passes sequentially through single-pass
Road water pigtail, single channel drilling rod and single channel water-jet punching press pipe nipple flow to drill bit, cooling drill bit and row during drilling
Slag guarantees that drilling is normally carried out；
(4) water-jet punching press: implement water-jet stamping press during drilling construction terminates, moves back brill, need to carry out at this time
Following operation, closes low pressure penstock, opens high pressure water valve, and high pressure water flows into single-pass through single channel water pigtail, single channel drilling rod
Road water-jet punching press pipe nipple simultaneously acts on spool combination, and the channel of cutting connection drill bit, high pressure water, which changes its course, converges to nozzle spray
Out, water-jet stamping press is carried out；
(5) switching punching press state is drilling state: at the end of the punching of certain point or fracturing work, high pressure water valve is closed,
Spool using the internal pressure of relief valve off-load single channel water-jet stamping device, in single channel water-jet punching press pipe nipple
Combination restPoses, and is then turned on low pressure penstock, and low pressure water passes through single channel water pigtail, single channel drilling rod and single channel waterpower
Injection punching press pipe nipple flows to drill bit, carries out moving back brill operation；
(6) punching or fracturing work are repeated: moving back and is drilled into next punching or fracturing work point, repeats step (4) and step (5).
7. a kind of single channel water-jet process for stamping using device as claimed in claim 6, it is characterised in that: step (3)
In drilling process, when low pressure water flows to drill bit by single channel water-jet punching press pipe nipple, extension spring is in spool combination
Nature, the entrance of nozzle are blocked by the outer circumference surface of top plate, and low pressure water is followed by the water flow on the entrance of through-hole, top plate
The outlet in channel and through-hole, eventually flows to drill bit.
8. a kind of single channel water-jet process for stamping using device as claimed in claim 6, it is characterised in that: step (4)
In water-jet punching course, when high pressure water flows into single channel water-jet punching press pipe nipple, high pressure water is acted in spool combination
Top plate, make top plate forward slip that sliding lock is sent into locked groove, block the outlet of through-hole, the channel of cutting connection drill bit, high pressure water
Change its course and converge to nozzle ejection, carries out water-jet stamping press.
