Background technology
Current coal bed gas field at home, most well site does not also all realize Digital Control, daily management and test job all will by manually having come, a wherein important job is exactly need frequently to test dynamic oil level, due to the design feature of coal bed gas well production tree, pressure meter is generally arranged on the plug of sleeve opening, all need during each test level first to pull down with manometric plug, switch four sleeve valves, whole test job is wasted time and energy, easy damage pressure meter, reduces the application life of sleeve valve.
The subject matter that this test process exists has:
(1) pressure meter often changing well head damage is needed;
(2) frequent switching sleeve pipe valve, be easy to cause valve seal tight, thus cause well head to leak gas, one of consequence of generation have impact on gas production, causes economic loss, two be cause fuel gas around well head to exceed standard, there is potential safety hazard;
(3) workload of on-the-spot test is large, and completing once test needs to carry special tool, and at least wants two people to coordinate, and utilizes special adhesive tape twice before and after also wanting, process well head thread seal problem;
(4) liquid level test instrument body is long-pending comparatively large, carries inconvenience.
The appearance of above situation, cause this traditional test methods time and effort consuming always adopted, efficiency is low, and cost is high and there is potential safety hazard.
Summary of the invention
The utility model, in order to test mining well dynamic oil level fast, safely, accurately, provides a kind of Portable coal-seam gas patrol testing arrangement.
The utility model adopts following technical scheme:
A kind of Portable coal-seam gas patrol testing arrangement, comprise connect successively from the bottom to top snap joint, receiving system and percussion lock, described receiving system comprises acoustic pressure wave reception cavity and acoustic receiver microphone, acoustic receiver microphone is fixed on the inside wall of acoustic pressure wave reception cavity by Wiring port, and the lateral wall of acoustic pressure wave reception cavity is also connected with pressure meter.
Described percussion lock comprises the installation cavity that be connected through with acoustic pressure wave reception cavity, there is operating grip at the top of installation cavity by pinned connection, the inside of installation cavity is provided with cone seal bar, cone seal bar is socketed with Compress Spring, cone seal masthead end contacts with the downside of operating grip, the side of installation cavity is also provided with exhaust opening, and exhaust opening is by the taper surface one-way sealing of cone seal bar.
Described percussion lock is gas storage capsule, and the opening end of gas storage capsule is connected through by seal nipple with acoustic pressure wave reception cavity.
Described pressure meter is shockproof pressure gage.
The utility model has following beneficial effect:
1, the pressure meter that former Christmas tree casing is installed is replaced with snap joint, connect testing arrangement described in the utility model by snap joint, reduce the damage to well head pressure gauge to greatest extent;
When 2, utilizing this device to test down-hole level, only this device need be connected with snap joint on coal bed gas well sleeve pipe plug, do not need to remove and install sleeve pipe plug, do not need switch head valve, do not need to do any change to oil well, thus can not destroy well site environment, there will not be additional construction operation, comprehensive use cost is low, and also without any danger, safety factor is higher;
3, utilize this device can test out casing pressure in well fast in well site, down-hole coal bed level can be obtained fast by Test Host, make on-the-spot test operation efficiency improve 5 to 10 times;
4, this apparatus structure is compact, easy to carry, and a people gets final product fitting operation, is adapted at promoting the use of in the coal-bed gas exploitation operation of operating mode complexity, less stable.
Accompanying drawing explanation

Fig. 2 is that down-hole is without apparatus structure schematic diagram during pressure;
In figure: 1-snap joint, 2-pressure meter, 3-acoustic pressure wave reception cavity, 4-Compress Spring, 5-cone seal bar, 6-exhaust opening, 7-operating grip, 8-Wiring port, 9-acoustic receiver microphone, 10-installation cavity, 11-bearing pin, 12-plug, 13-seal nipple, 14-gas storage capsule.
Detailed description of the invention
By reference to the accompanying drawings, detailed description of the invention of the present utility model is described further:
Described Portable coal-seam gas patrol testing arrangement, comprise connect successively from the bottom to top snap joint 1, receiving system and percussion lock, described receiving system comprises acoustic pressure wave reception cavity 3 and acoustic receiver microphone 9, acoustic receiver microphone 9 is fixed on the inside wall of acoustic pressure wave reception cavity 3 by Wiring port 8, and the lateral wall of acoustic pressure wave reception cavity 3 is also connected with pressure meter 2.
First, being detected the pressure in coal bed gas well by pressure meter 2, because underground working is complicated, for ensureing accuracy of detection, generally adopting shockproof pressure gage.
When down-hole is for there being a pressure condition, when being namely in normal pump drainage gas, percussion lock adopts structure as shown in Figure 1, from diagram, described percussion lock comprises the installation cavity 10 that be connected through with acoustic pressure wave reception cavity 3, there is operating grip 7 at the top of installation cavity 10 by pinned connection, the inside of installation cavity 10 is provided with cone seal bar 5, cone seal bar 5 is socketed with Compress Spring 4, the bottom of Compress Spring 4 is fixed by plug 12, cone seal bar 5 top contacts with the downside of operating grip 7, the side of installation cavity 10 is also provided with exhaust opening 6, exhaust opening 6 is by the taper surface one-way sealing of cone seal bar 5.
