The gas drilling dust guard
Technical field
The utility model relates to gas drilling protector technical field, is a kind of gas drilling dust guard.
Background technology
The gas drilling technology has great contribution at aspects such as improving rate of penetration, shortening drilling period, reduction drilling cost, discovery and protection oil gas field and raising oil gas production capacity, and this technology has obtained application more widely in the suitable zone of geological conditions since producing.But, because gas drilling is with the medium of pure gas as the drilling well circulation, the shaft bottom landwaste that produces in drilling process returns in annular space to the process on ground, landwaste can run foul of each other, the while landwaste is impact drill string, the borehole wall and wellhead equipment constantly, and a large amount of subsequently dust cause the air quality of situ of drilling well relatively poor along with air-flow is disposed to the atmosphere from the sediment outflow pipeline, simultaneously local environment is polluted, and the staff's at scene personal safety is threatened.
Summary of the invention
The utility model provides a kind of gas drilling dust guard, overcome the deficiency of above-mentioned prior art, it can effectively solve, and the on-the-spot air quality that exists in the existing gas drilling process is poor, contaminated environment and problem that the staff's at scene personal safety is threatened.
The technical solution of the utility model realizes by following measure: a kind of gas drilling dust guard, comprise sediment outflow pipe, tube connector and water tank, at the sediment outflow pipe switch valve is arranged fixedly, the top of switch valve is positioned at the sediment outflow pipe, the lower end of switch valve and the upper end of tube connector are fixed together, water pump is arranged in water tank, and the lower end of tube connector is fixed on the delivery port of water pump.
Be the further optimization and/or improvements to above-mentioned utility model technical scheme below:
Above-mentioned can have angle between switch valve and sediment outflow pipe, angle is between 30 degree are spent to 45.
Above-mentioned tube connector can be colloid flexible pipe tube connector, and switch valve is the irony switch valve, on the sediment outflow pipe by being welded with the irony switch valve.
The lower end of above-mentioned switch valve and the upper end of tube connector are fixed together by clip, and the lower end of tube connector is fixed on the delivery port of water pump by clip.
Above-mentioned switch valve can be ball valve or stop valve.
Above-mentioned water pump can be stock pump or submersible pump.
The utility model reasonable and compact in structure, easy to use, it is in the gas drilling process, can make dust sedimentation effectively, improve on-the-spot air quality, prevent the pollution of natural environment, guaranteed situ of drilling well personnel's personal safety, had simultaneously and be easy to make the characteristics low with cost.
Description of drawings
Accompanying drawing 1 is the main TV structure schematic diagram of the utility model most preferred embodiment.
Coding in the accompanying drawing is respectively: 1 is the sediment outflow pipe, and 2 is tube connector, and 3 is water tank, and 4 is switch valve, and 5 is water pump, and 6 is clip, and α is angle.
The specific embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
In the utility model, for convenience of description, the description of the relative position relation of each parts all is that the Butut mode according to Figure of description 1 is described, as: the position relation of forward and backward, upper and lower, left and right etc. is what to determine according to the Butut direction of Figure of description 1.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
As shown in Figure 1, this gas drilling dust guard comprises sediment outflow pipe 1, tube connector 2 and water tank 3, at sediment outflow pipe 1 switch valve 4 is arranged fixedly, the top of switch valve 4 is positioned at sediment outflow pipe 1, the upper end of the lower end of switch valve 4 and tube connector 2 is fixed together, water pump 5 is arranged in water tank 3, and the lower end of tube connector 2 is fixed on the delivery port of water pump 5.The effect that water in the water tank 3 is transported to sediment outflow pipe 1 inside is played in the setting of water pump 5.
Can according to actual needs above-mentioned gas drilling well dust guard be made further optimization and/or improvements:
As shown in Figure 1, between switch valve 4 and sediment outflow pipe 1 angle α is arranged, angle α is between 30 degree are spent to 45.The setting of angle α can prevent effectively that dust-containing air stream from entering the generation of the situation of switch valve 4 inside and the pipeline that results in blockage.
As shown in Figure 1, tube connector 2 is colloid flexible pipe tube connector.The use of colloid flexible pipe can improve installation flexibility, and switch valve 4 is the irony switch valve, on sediment outflow pipe 1 by being welded with irony switch valve 4.
As shown in Figure 1, the upper end of the lower end of switch valve 4 and tube connector 2 is fixed together by clip 6, and the lower end of tube connector 2 is fixed on the delivery port of water pump 5 by clip 6.
As shown in Figure 1, switch valve 4 is ball valve or stop valve.
As shown in Figure 1, water pump 5 is stock pump or submersible pump.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
The use of the utility model most preferred embodiment: at first, start water pump 5, water pump 5 is pumped the water in the water tank 3 to sediment outflow pipe 1 by tube connector 2 and switch valve 4 successively, water and dust-containing air stream are mixed into vaporific, when dust with after water smoke mixes, dust can access effective sedimentation, has prevented the dust pollution in the gas drilling process effectively.
