Abstract
A gas-water separation pressure testing device of a gas drilling hole comprises a closed container unit and a pressure testing unit. The closed container unit comprises a closed pressure testing container, wherein ventilation holes are formed in the upper end of the pressure testing container, a closed water level observation window is formed in the side face of the pressure testing container, the ventilation holes of the pressure testing container are formed in the upper end and the lower end in the water level observation window respectively, the ventilation holes are closed through bolts, and a water outlet sluice valve is arranged at the lower end of the pressure testing container. The pressure testing unit comprises a hole opening flange and a pressure gage, wherein the hole opening flange is connected with a tee pipe, one pipe opening of the tee pipe is connected with the pressure gage through a bend, and another pipe opening of the tee pipe is connected to the upper portion of the pressure testing container through a water discharge hose and is provided with a water control sluice valve. The gas-water separation pressure testing device of the gas drilling hole effectively ensures reality of tested pressure data, improves the success rate of testing the pressure of the drilling hole, avoids the situation that pressure tested out is water pressure due to the fact that water in the hole cannot be drained, has the advantages of being little in investment and high in practicability, and is suitable for testing the pressure of the gas drilling hole in the fracture development area in a pit.
Description
Technical field
The utility model relates to drilling technique field, colliery, is specifically related to a kind of gas boring gas-water separation pressure tester.
Background technology
At present, along with mining depth strengthens and the lacking of newly developed area gas pressure data, the mine gas problem is more and more outstanding, in October, 2008 through China Mining University to II1, II2 exploiting field 7
2, 7
3, 8
2Determination of coal seam gas pressure, all there is anomaly, gas diffuses the destruction type of hardness, coal of initial velocity △ P, coal all above " coal and gas outburst mine evaluation standard " (AQ1024-2006) outburst danger threshold, be the outburst hazard coal seam, appointed the colliery, building to upgrade to coal and gas outburst mine on June 1st, 2009.
There was multifactor impact in the boring that construction is good in the pressure measurement process: 1, after the drilling and sealing slip casting, after loading onto pressure meter, because of bad sealing or lack of standardization, cause boring can not survey pressure; 2, because of the geological conditions complexity, sandstone crevice water is composed and to be deposited abundantly, causes in the pressure measurement boring water being arranged, thereby what measure all is hydraulic pressure, and what manifest on the pressure meter is not gas pressure; 3, immature owing to the boring slurry injection technique is grasped, can not will hole interior water blocking firmly sometimes during slip casting, thus normally pressure measurement.
How guaranteeing really to measure gas bearing capacity or the remaining pressure of gas in the hole, the gas pressure authenticity of measuring under the regimen condition is arranged in the hole of particularly holing, is the key point of pressure measurement.For head it off, cut the waste to greatest extent, the success rate of economical with materials, raising pressure measurement boring, need a kind of gas rational in infrastructure boring of design gas-water separation pressure tester.
The utility model content
The technical problem that the utility model solves is to provide a kind of gas boring gas-water separation pressure tester, thereby solves the problem in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of gas boring gas-water separation pressure tester, comprise closed container unit and pressure measuring unit, described closed container unit comprises airtight pressure measurement container, the upper end of described pressure measurement container is provided with air vent, the side of described pressure measurement container arranges airtight water level observation port, two ends are provided with the air vent of pressure measurement container about in the described water level observation port, and described air vent utilizes bolt to seal, and the lower end of described pressure measurement container is provided with out Water gate valve; Described pressure measuring unit comprises aperture flange and pressure meter, described aperture flange is connected with tee piece, curved leading to of a mouth of pipe utilization of described tee piece connects described pressure meter, and another mouth of pipe utilization flexible pipe that discharges water is connected to the top of described pressure measurement container, and is provided with the control Water gate valve.
As a kind of improvement, described pressure measurement container is provided with control water and the gate valve that discharges water.
As a kind of improvement, the sidewall of described pressure measurement container is provided with in order to observe the airtight water level observation port of internal liquid amount.
The utility model after slip casting in the boring, smothers boring with the aperture flange in use, can observe pressure by pressure meter, and water is put into the pressure measurement container, shows according to water level in the water level observation port of pressure measurement container and goes to discharge water.Method discharges water: close the control Water gate valve of pressure measurement container upper end earlier, open the Water gate valve that of pressure measurement container lower end again, the bolt of then twisting pressure measurement container upper end air vent gets final product.
Owing to adopted above structure, the utlity model has following beneficial effect:
1, pressure measurement data are true, stable.By using the utility model, pressure measurement boring for water outlet in the hole, sometimes bad to the water slip casting plugging effect in holing, and water is heavy, gas is light, and the water that causes not having shutoff to annotate in the hole all concentrates on the place, aperture, thereby gas is blocked by place, aperture water resistance in the hole, can not pass, thereby what cause measuring all is hydraulic pressure, has influenced gas boring pressure measurement data, can avoid because there being water can not normally measure gas pressure in the hole by adopting the utility model.
2, simple, the good seal performance of manufacture craft, operating procedure are simple, convenient and practical, and do not influence manometric normal pressure measurement data between blowoff period.
3, saved man-hour, improved effect, saved cost.Improve the success rate of pressure measurement boring simultaneously, avoid not survey and press secondary construction drill again, incur loss through delay the duration.
4, reduce investment, increased benefit, saved material and fund.
In a word, the utility model has effectively guaranteed the authenticity of pressure measurement data; Improve the success rate of pressure measurement boring pressure measurement; What stopped have water can't get out in the hole simultaneously and measure all is hydraulic pressure; Have small investment, practical characteristics, be applicable to the gas boring pressure measurement of cranny development area, down-hole.
