Description
Technical field
The present invention relates to it is a kind of by remote location, using retail natural gas, page of the defeated mode of pipeline collection without economic benefit
Rock gas, associated gas etc. carry out safe efficient, inexpensive recycling and are filled into the device of CNG long-tube trailers, and in particular to one
The outlying well natural gas recycling device of kind, belongs to gas gathering and transportation engineering field.
Background technology
The Unconventional gas gas field such as conventional gas gas field and shale gas is during exploration and development, due to needing to bore
Prospect pit, the evaluation reasons such as well, inevitably will produce that some yield are relatively low, scattered outlying individual well away from gas gathering station again farther out.
In addition, oil field is in the process of development, part associated gas can be generated from crude oil, main component is also CH4, but yield compared with
It is low.These above-mentioned natural gas resources due to low output, away from gas gathering station farther out, according to conventional construction collecting pipe conveying side
Formula, it is clear that will not have business development value.For associated gas, if not recycled to it, general at present
It can be handled using type discharge air-fuel burning, both waste resource, will also generate substantial pollution to ambient enviroment.
Currently, the domestic exploitation way of recycling for being directed to retail natural gas, mainly has CNG, LNG, natural gas to generate electricity on the spot, day
The modes such as right gas adsorption storage, gas hydrates solidification storage.Domestic application it is more be CNG recovery technologies, main work
Skill is natural gas by separation, voltage-regulation voltage-stabilization, desulfurization, dehydration, de- hydrocarbon, then with injection CNG long tubes after compressor boost to 20MPa
Trailer, then sold as CNG commodity gas by CNG long-tube trailers roping CNG gas stations or roping is to natural gas collecting station, outer defeated
The yard injection collection inside gas fields such as stand is defeated or outer defeated pipe network, to realize that marginal natural gas without any commercial value carries out to this
Efficiently, low cost recycling.
But current existing retail natural gas CNG retracting devices have the following disadvantages：1) heat, detach, filtering, being dehydrated,
The sled block such as compression, metering is separately provided, and is not integrated, and after each sled block is by truck transport to well site, is hung respectively in well
On the basis of, each connecting line prized between block is all made of steel pipe connection, and movement, installation, the dismounting of package unit take
Arduously, be only applicable to carry the lower outlying well of high pressure stable yields of the frequency recycling, be not suitable for yield it is relatively low, need frequently resettlement
Between drive a well the recycling of retail natural gas；2) dehydration device for having retracting device is not provided with bypass, and recycling gas only considered
Sell as CNG commodity gas or roping is to gas fields inside yard injection pipe nets such as natural gas collecting station, outer defeated stations, it cannot
Meet the practical need that part gas field requires retracting device to can not only be used for the sale of CNG commodity gas, can also inject pipe network inside gas field
It asks.
Invention content
Present invention aims to overcome that above-mentioned technological deficiency, provides a kind of retail natural gas retracting device.The device recycles
It is simple for process, suitable for opening the recycling of outlying well between the outlying well of quantity-produced stable yields and interruption production, decline to well head pressure
It is adaptable to subtract variation, recycling gas can not only be used for the sale of CNG commodity gas, and pipe network, application range can be also injected inside gas field
Extensively.
To achieve the above object, the present invention is as follows using technical solution：
A kind of outlying well natural gas recycling device, used device include mainly water batch heater, gas-liquid separator, mistake
