Description
Technical field
The present invention relates to a kind of by remote location, use the defeated mode of pipeline collection without the retail natural gas of economic benefit, shale gas, oil field
Associated gases etc. carry out device safe efficient, that low cost reclaims and be filled into CNG long-tube trailer, are specifically related to a kind of outlying well
Natural gas recycling device, belongs to gas gathering and transportation engineering field.
Background technology
The Unconventional forage gas fields such as conventional gas gas field and shale gas are during exploration and development, owing to needs drill well, evaluation
The reasons such as well, inevitably produce some yield relatively low, away from gas gathering station scattered outlying individual well the most farther out.Additionally, oil field
On stream, can produce part associated gas from crude oil, its main component is also CH4, but yield is relatively low.Above-mentioned
These natural gas resources owing to yielding poorly, away from gas gathering station farther out, according to conventional construction collecting pipe mode of movement, it is clear that will
Do not have business development to be worth.For associated gas, if it not being reclaimed, the most typically can only use and continuing
Emptying burn processing, had both wasted resource, also surrounding will have been produced substantial pollution.
At present, the domestic exploitation way of recycling for retail natural gas, mainly there are CNG, LNG, natural gas to generate electricity on the spot, natural gas
The modes such as adsorption storage, gas hydrates solidification storage.What domestic application was more is CNG recovery technology, and its main technique is
Natural gas via cross separation, voltage-regulation voltage-stabilization, desulfurization, be dehydrated, de-hydrocarbon, then with injecting CNG length after compressor boost to 20MPa
Pipe trailer, then sold as CNG commodity gas by CNG long-tube trailer roping CNG gas station, or roping is to natural gas collecting
Stand, the internal yard in the gas field such as outer defeated station is injected and is collected defeated or outer defeated pipe network, thus realizes natural without the limit of any commercial value to this
Gas is carried out efficiently, low cost reclaims.
But current existing retail natural gas CNG retracting device has the disadvantage that 1) heat, separate, filter, be dehydrated, compress,
The sled blocks such as metering are separately provided, and do not carry out integrated, after each sled block is by truck transport to well site, hang respectively on basis, well site
On, the connecting line between each sled block all uses steel pipe to connect, and the movement of package unit, installs, dismantles time and effort consuming,
It is only applicable to carry the recovery of the relatively low outlying well of high pressure stable yields of the frequency, is not suitable for that yield is relatively low, needs to open between frequently resettlement
The recovery of well retail natural gas；2) the dehydration device of existing retracting device is not provided with bypass, reclaims gas and only considered as CNG
Commodity gas sell or roping to natural gas collecting station, outer defeated station etc. the internal yard ascending pipe net in gas field, it is impossible to meet part
Gas field requires that retracting device can not only be used for CNG commodity gas and sells, also can inject inside gas field the actual demand of pipe network.
Summary of the invention
Present invention aim to overcome that above-mentioned technological deficiency, it is provided that a kind of retail natural gas retracting device.This device recovery process is simple,
It is applicable to the outlying well of quantity-produced stable yields and is interrupted the recovery opening outlying well between production, well head pressure attenuation change is adapted to energy
Power is strong, reclaims gas and can not only be used for the sale of CNG commodity gas, it is possible to injects pipe network, applied range inside gas field.
For achieving the above object, the present invention uses technical scheme as follows:
