Description
Technical field
Natural gas extraction technical field is the utility model is related to, more particularly to it is a kind of for pressure on-site supervision, long-range prison
Control and the multi-functional pressure obtaning device of medicament injection.
Background technology
Among natural gas is equally imbedded in the geological structure of underground sealed with crude oil, some and oil reservoir are in same layer
Position, some individualisms.For mined together with crude oil with natural gas of the oil reservoir in same layer position, meeting.For
Existing for only single-phase gas, we term it gas reservoir, and its recovery method was both quite similar with crude oil production method, has it special again
Different place.Natural gas extraction natural gas and crude oil first is the same with bottom water or side water is often a storage system.With day
The exploitation process of right gas, the elastic energy of water body can drive water to scurry into gas reservoir along high permeability zone.In this case, due to rock
The hydrophily of itself and the effect of capillary pressure, the intrusion of water are not effectively displacing gases, but closing seam fracture hole hole or
Undischarged gas in space, form Si Qi areas.By trap in the high pressure gas of water enchroachment (invasion) band, quantity can be up to rock pore for this part
The 30%~50% of gap volume, so as to greatly reduce the ultimate recovery of gas reservoir.Secondly after gas well production water, gas flows into shaft bottom
Filtrational resistance can increase, and gas-liquid two-phase will significantly increase along the upward pipe stream total power consumption of oil well.
To add a pressure obtaning device on the gas recovery facility of existing gas field gas production, pipeline, the pressure obtaning device includes an air collecting pipe
Road, flowline one end are connected with surface casing pressure or Oil-pressure joint, and the other end is installed a corresponding pressure gauge and is used for well head
The pressure of casing pressure or oil pressure carries out field monitoring, and this pressure obtaning device can realize that field data monitors, but can not realize simultaneously remote
Range monitoring；Gas recovery facility, pipeline be through needing to carry out the process such as medicament injection after a while, it is necessary to which pressure gauge is removed simultaneously,
Then install filing provision additional to inject medicament, so as to cause, process is more, pressure gauge is fragile, operating efficiency is low.
It is CN201420736496.4 separately to have China Patent No., discloses a kind of medicament addition dress for reclaiming well casing gas
Put, belong to well recovery technical field.The medicament adding device includes：The medicament storage tank body of top sealing；In the medicament
Store the medicament discharge pipe of tank base connection；The medicament discharge pipe is used to be connected with well mouth of oil well sleeve pipe pipeline；With
The gas equalizing line for connecting at the top of the medicament storage tank body and being connected with the medicament discharge pipe；Stored up positioned at the medicament
Deposit the medicament addition funnel at the top of tank body；And the bleeder pipe at the top of the medicament storage tank body.Can be with from above-mentioned patent
Find out, at present after all individually the carrying out the device of dosing or the pressure gauge of monitoring dismantles of oil well field, utilize pressure
The interface access medicament charging point of table carries out medicament addition, troublesome in poeration, often dismantles fragile parts.
Utility model content
The defects of in order to overcome prior art, the utility model provide a kind of multi-functional pressure obtaning device, the pressure obtaning device
The operation such as pressure on-site supervision and remote monitoring, medicament injection can be realized simultaneously, it is safe to use, easy to maintenance.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
