Abstract
The invention relates to a gas drilling water-proof device, in particular to a negative-pressure centralized control device for a kilometer drilling machine, and aims to solve the problems of transfinite gas and the like caused by unreasonable design of the water-proof device in the drilling work of the kilometer drilling machine. The negative-pressure centralized control device for the kilometer drilling machine comprises a bracket, an upper iron pipe arranged on the upper side of the bracket, and a lower iron pipe is arranged on the lower side of the bracket, wherein plugs or end covers are welded at the two ends of the upper iron pipe and the lower iron pipe; both sides of the upper iron pipe are provided with water outlet pipes; the water outlet pipes are provided with drainage valves; the lowermost points of the water outlet pipes are flush with the lowermost points of the upper iron pipe; the upper side of the upper iron pipe is provided with a drilling orifice negative-pressure connection port, a gas-water separator negative-pressure connection port, a standby negative-pressure connection port and a reducing straight pipe in sequence; a baffle plate is arranged at a position between the standby negative-pressure connection port and the reducing straight pipe inside the upper iron pipe.
Description
Technical field
The present invention relates to a kind of gas drilling water-tight device, be specially a kind of km rig negative pressure centralized control equipment.
Background technology
VLD-1000 type km rig is existing is one of main drilling equipment in my ore deposit, and construction drill has that polarization is accurate, drilling depth long, single hole gas density and pumping volume high.Drill along with rig, needing the gas to discharging to carry out instant extraction, avoiding gas density to transfinite, affecting safe construction.But the first quarter in 2012, km rig gas exceeding limit accident occurred time and again in my ore deposit, emergency case met by km rig in drilling construction process cannot effective control gas, and main cause is that the original ancillary facility of drilling used exists more hidden danger., there is shortcomings in the octal delivery box such as used, because casing adopts iron sheet multiple welding, body is firm not, there will be casing " breathing " situation, cause welding box body place fatigue to burst apart under the effect of continuous print negative pressure variation.Easily pile up cinder in case, not easily rinse.Casing is non-dismountable, heavy, removal of home difficulty.Have a strong impact on negative pressure when discharging water, in the process that repeatedly discharges water, negative pressure reduces to cause to transfinite.And return the water capacity and easily cause the problems such as main line blocking by casing inspiration main line.
Summary of the invention
The present invention, in order to solve km rig in drilling work, causes the problems such as gas exceeding limit because water-tight device design is unreasonable, provides a kind of km rig negative pressure centralized control equipment.
Technical scheme of the present invention is, a kind of km rig negative pressure centralized control equipment, the lower iron pipe comprising support, be arranged on the upper iron pipe on the upside of support and be arranged on the downside of support, upper iron pipe and lower iron pipe two ends welding plug or end cap, upper iron pipe both sides are provided with outlet pipe, outlet pipe is provided with water discharging valve, described outlet pipe minimum point is concordant with the minimum point of upper iron pipe, drilling orifice negative pressure connector, moisture trap negative pressure connector, negative pressure connector for subsequent use and reducing straight pipe is provided with successively, upper iron pipe on the upside of upper iron pipe.Inner upper negative pressure connector for subsequent use and reducing straight pipe between position be also provided with baffle plate.
The upside of lower iron pipe end is provided with tube connector, and bottom is provided with adjutage, and adjutage is provided with Draw off valve, and minimum point and the lower iron pipe minimum point of adjutage flush.
Connected by flexible pipe between outlet pipe and tube connector.
Described baffle plate is semicircle orifice plate.The not block water flowing of baffle plate bottom, top ensures Gas Flow.
The diameter of reducing straight pipe bottom is less than the diameter on top.
Containing materials such as water, coal slime, coal dusts from the gas that gas drilling is gushed out, after gas enters iron pipe, water and coal slime deposit to bottom, and gas is then discharged in main pipeline by reducing straight pipe.Baffle plate can filter and stop the coal slime of iron pipe side to move to position below reducing straight pipe.The upper diameter of reducing straight pipe becomes large, and when water and methane gas upwards enter after in pipe together with under suction function, diameter becomes suddenly large, and water then loses pressure, and automatically fall back in upper iron pipe, anti-sealing is sucked into main pipeline.
During draining, first water deposit in upper iron pipe, then automatically flows into deposition in lower iron pipe.When needing to discharge water, by the valve closing at upper iron pipe two ends, open the Draw off valve at lower iron pipe two ends, water flows out, and upper iron pipe is closed, and negative pressure hold mode, does not affect drilling-draining.Prevent gas exceeding limit.
Compared with prior art, the present invention has following beneficial effect:
1, be bolted between support and two iron pipes, be that dismountable flexible pipe connects between two iron pipes, installation and removal are easy, convenient in carrying,
2, use the iron pipe cast as carrier, cylindrical structure tolerance is strong, and be not stressed variable effect structural safety.
3, the cascaded structure of upper and lower two iron pipes, keep closing when lower iron pipe discharges water and between upper iron pipe, in guarantee, in iron pipe, negative pressure is constant.
4, upper iron pipe and lower iron pipe two ends are all provided with discharge tube, if there is coal slime to block, directly connected by high-pressure water pipe and rinse.Simply easy to maintenance.
5, use that reducing is straight-through to be connected with main pipeline, can anti-sealing and coal slime enter in main pipeline.
