Background technology
Among natural gas is also equally imbedded in the geological structure of underground sealed with crude oil, some and oil reservoir are in same layer
Position, some individualisms.It, can be mined together with crude oil for the natural gas with oil reservoir in same layer position.For
Existing for only single-phase gas, we term it gas reservoir, recovery method was not only quite similar with crude oil production method, but also had its spy
Different place.With gas extraction process, the elastic energy of water body can drive water to scurry into gas reservoir along high permeability zone.This
In the case of, due to the hydrophily of rock itself and the effect of capillary pressure, the intrusion of water not instead of not effectively displacing gases,
Undischarged gas in closing seam fracture hole hole or gap forms the areas Si Qi.This part is by trap in the high pressure gas of water enchroachment (invasion) band, quantity
It can be up to the 30%~50% of rock pore volume, to greatly reduce the ultimate recovery of gas reservoir.Secondly gas well production
After water, the filtrational resistance that gas flows into shaft bottom can increase, and gas-liquid two-phase will be significantly increased along the upward pipe stream total power consumption of oil well.
As what water enchroachment (invasion) influenced increasingly sharpens, the gas producting rate of gas reservoir declines, and the blowing reduced capability of gas well, well yield is passed rapidly
Subtract, stops production up to the serious ponding in shaft bottom.It is current to administer gas reservoir flood mainly from two aspects, when draining, first, water blockoff.
When earth-moving equipment is dug to that layer of natural gas, the spilling of natural gas can not be closed in time, natural gas is a kind of inflammable gas, machine
Tool equipment part activity will produce fragmentary spark, easily set off an explosion.

Dug to when digging to that layer of natural gas when digging bar 67, natural gas namely for methane is gradually revealed, along digging 67 center of bar into
Enter unearthed pipeline 610, then spread, gas enters from ventilation net 611 in gasmetry chamber 612, and methane detector 615 detects
Methane gas is transferred to data processing centre 611, and data processing centre 611 starts transmission mechanism 64 after handling, by the first skin
The transmission of belt wheel 642 and the first taper cone pulley 647 pulls the first steel cable 641 that rotating wheel 658 is caused to rotate, subsequent third belt pulley
657 also rotate therewith so that the swivel plate 651 connected therewith by driving belt 656 rotates therewith, and catch bar 654 is done
It pumps, 653 vertical depression of the first spur rack causes 661 disequilibrium of the first lever, the other end in this process
It raising up, payout allows clump weight 666 because the gravity of itself pushes, and catch bar 667 pushes rotating disc 668 to move in a circle,
Again by the transmission of the second taper cone pulley 669, allow the extension of telescopic rod 6610 that sealing plate 6611 is pushed out, sealing plate 6611 is through digging
It being matched with wedge mouth 681 after bar 67, the channel of bar 67 is dug in closing, avoids methane gas from spreading, while pushing mobile bar 682,
Rope is pulled, runner 688 is caused to rotate, compression bar 689 pushes so that bar 6811 passes through the perforation of sealing plate 6611, Gu
Fixed column sealing plate 6611, make its will not retraction run-off the straight loosen, it is artificial to press bar 6811 when needing to reset
The spring button of bottom makes its bar 6811 reset, and then 63 backwards rotation of motor drives other component gradually to set back i.e.
It can.
Data processing centre 611 of the present invention is the integrated circuit board with data processing function.
Problems solved by the invention is can not to close overflowing for natural gas in time when earth-moving equipment is dug to that layer of natural gas
Go out, natural gas is a kind of inflammable gas, and mechanical machine part activity will produce fragmentary spark, easily set off an explosion, and the present invention passes through
Above-mentioned component is combined with each other, and the present invention is equipped with gas detection structure 61, sealing pushing structure 66, automatic-sealed structure 68,
During shoveling, when digging to that layer of natural gas, methane leakage, after the methane detector 615 by gas detection structure 61
By data processing then starter motor 63 of data processing centre 611, then transmission mechanism 64 starts, and balance mechanism 65 balances
Upper and lower driving force improves the stability of transmission, and it is to prevent sealing plate 6611 from moving that bar 67 is dug in the then closing of sealing plate 6611
Dynamic, sealing pushing structure 66 is closed, and is prevented methane gas from revealing, is set off an explosion.
