Description
Technical field
The invention belongs to coal-bed gas exploitation field, more particularly to a kind of static expanding agent flow in pipes fixing device and fixation
Method.
Background technology
Static expanding agent with cheap, expansion rate and the cycle it is controllable, noiseless, it is without friction the features such as be widely used in nothing
The multiple fields such as sonic boom is broken, traffic, urban construction and industrial and mining enterprises.It is increase coal at all for solve low-permeability coal seam extraction problem
Layer gas permeability, using the measure that static expanding agent is injected in coal seam.Static expanding agent flow in pipes is placed in coal bed drilling,
In static expanding agent injection process, due to pressure effect and flow in pipes diameter is more much smaller than bore diameter；Flow in pipes
Easily rocked in drilling or pipeline is slid in tunnel, influenceed injection efficiency, waste static expanding agent medicament.
The content of the invention：
The technical problem to be solved in the present invention is：A kind of static expanding agent flow in pipes fixing device and fixing means are provided, with
Solve prior art static expanding agent flow in pipes to be placed in coal bed drilling, in static expanding agent injection process, due to pressure
The effect of power and flow in pipes diameter is more much smaller than bore diameter；Flow in pipes is easily rocked in drilling or pipeline is slid in lane
In road, injection efficiency is influenceed, the technical problems such as static expanding agent medicament are wasted.
Technical solution of the present invention：
A kind of static expanding agent flow in pipes fixing device, it includes being cased with hollow cylinder on hard drainpipe, hard drainpipe, covered
The hard drainpipe for having hollow cylinder is placed in drilling, and the feed end of hard drainpipe is connected with flow in pipes.
The bottom of hollow cylinder is provided with fastener, and fastener is fixed in the groove on hard drainpipe.
The top of hollow cylinder is provided with fastener, and fastener is fixed in the groove on hard drainpipe.
The feed end of hard drainpipe is connected with flexible steel in flat section tubing, and flow in pipes is entered by flexible steel in flat section tubing and hard drainpipe
Expect end connection.
The diameter of hollow cylinder is smaller than bore diameter 3-5 millimeters.
Fastener is plastics or metal material, is two semicircular structure compositions, is tied two semicircles by two bolts
Structure is fixed together.
A kind of fixing means of static expanding agent flow in pipes fixing device, it includes：
Step 1, hollow cylinder is socketed in on recessed poor hard drainpipe, fixed hollow cylinder by fastener；Card
Part is arranged in groove；
Step 2, the hard drainpipe for being socketed with hollow cylinder is placed in coal bed drilling；
Step 3, the feed end of hard drainpipe connect static expanding agent flow in pipes by flexible steel in flat section tubing.
Beneficial effects of the present invention：
Hollow cylinder is socketed on hard drainpipe by the present invention, by setting fastener by hollow cylinder in hard drainpipe upper groove
Body is fixed, and hollow cylinder is arranged in coal bed drilling, and the feed end of hard drainpipe connects static expanding agent by connecting tube
Flow in pipes.It is allowed to when injecting swelling agent, the pipeline in drilling will not be rocked；It is allowed to difficult for drop-off；Solve static expanding
Pipeline is easily slid in tunnel in agent injection process, influences injection efficiency, the problems such as wasting static expanding agent medicament.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is isolation of components schematic diagram of the present invention.
Embodiment：
A kind of static expanding agent flow in pipes fixing device, it includes being cased with hollow cylinder on hard drainpipe 1, hard drainpipe 1
3, it is cased with the hard drainpipe of hollow cylinder 3（1）It is placed in drilling, the feed end of hard drainpipe 1 is connected with flow in pipes.
The bottom of hollow cylinder 3 is provided with fastener 2, and fastener 2 is fixed in the groove on hard drainpipe 1；With fixation hollow
Cylinder 3, is allowed to not move up and down on hard drainpipe 1.
Because when injecting swelling agent, pressure is very big, simply by the bottom of the fixation hollow cylinder 3 of fastener 2, open circles
Cylinder 3 still may up be beated, therefore be provided with fastener 2 at the top of hollow cylinder 3, and fastener 2 is fixed on hard drainpipe 1
Groove in.
The feed end of hard drainpipe 1 is connected with flexible steel in flat section tubing 4, and flow in pipes passes through flexible steel in flat section tubing 4 and hard drainpipe 1
Feed end connection.The present invention sets flexible steel in flat section tubing 4, enables to adapt to the expansion, contraction, deflection of flow in pipes,
Vibrations can be reduced, expansion and amount of contraction is absorbed；Hard drainpipe 1 and flow in pipes is avoided to be directly connected to the defect brought.
The diameter of hollow cylinder 3 is smaller than bore diameter 3-5 millimeters.Ensure that hollow cylinder 3 can be smoothly put into
In drilling, when also ensuring that injection, hollow cylinder 3 will not be rocked.
Easily load and unload and clean for the ease of device；Fastener 2 is plastics or metal material, is two semicircular structure groups
Into two semicircular structures are fixed together by two bolts.
A kind of fixing means of static expanding agent flow in pipes fixing device, it includes：
