Greatly, natural gas pile things on is under water, causing the fluid-carrying capability of gas-producing well to decline, it is impossible to realize blowing band liquid aerogenesis, part aquifer yield
Larger gas well stops production caused by hydrops.After stopping production, natural gas causes the great wasting of resources still in gas well, uses
There is the characteristics of big extraction amount of workload is small again in artificial extract.
In recent years, oil gas field has carried out multinomial water drainage-gas recovery technology research and experiment, current water-producing gas well water pumping gas production master
To use foam drainage gas recovery technique.Although foam drainage gas recovery technique is gradually improved and ripe, be due to gas well distribution,
Collect the limitation of gas transmission mode and technique, part gas well foam helps row to have certain difficulty.Implement rolling development in view of gas field, together
There is pressure unbalanced phenomena in one gas gathering station, low pressure, water production water-producing gas well gas gathering station part newly operation well pressure it is higher,
Production capacity preferably, in order to give full play to high pressure, the superiority of high production capacity of new Brought-in Gas Wells, in combination with yard process characteristic, is opened
Open up high-pressure air source gas well gas and lift water drainage-gas recovery technology technical research, achieve certain effect.But, the number of current high-pressure air source well
Amount is limited, it is impossible to fully meet the technical requirements of gaslift water pumping gas production.
In addition, the water drainage gas production device that foam drainage gas recovery technique is used can only extrude water and natural gas from gas well,
But the separation of water and natural gas can not be realized, therefore also need to moisture trap and separated, and this moisture trap into
This height, increases gas production input cost.
The content of the invention
It is an object of the invention to the shortcoming for overcoming prior art, there is provided a kind of compact conformation, the continuous supercharging gaslift of realization
Water pumping gas production, reduce gas-producing well hydrops stop production the loss caused, improve the high full-automatic row of water-producing gas well gas production, production efficiency
Water gas recovery facility.
The purpose of the present invention is achieved through the following technical solutions：A kind of Full-automatic drainage gas recovery facility, it includes control

Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below：
As shown in figure 1, a kind of Full-automatic drainage gas recovery facility, it include controller, natural gas compressor 1, nitrogen compressor 2,
Knockout drum 3 and the closure 5 for being fixedly arranged on the top of gas well 4, the described top of closure 5 are provided with joint 6 and connect gas
It is installed with delivery pipe 7 in the centre bore of well 4, centre bore, the vertical setting of delivery pipe 7, the bottom of delivery pipe 7 extends gas well 4
Interior, the upper end of delivery pipe 7 is extended outside gas well 4, and inlet 8 and discharge opeing are provided with the side wall of described knockout drum 3
Mouth 9, inlet 8 is connected with the upper end of delivery pipe 7, and high-pressure pump 10 is connected with leakage fluid dram 9, and the top of knockout drum 3 is set
There is gas outlet 11, gas outlet 11 is connected with the arrival end of natural gas compressor 1, and blast pipe 12 is provided with natural gas compressor 1,
Chuck 13 is cased with blast pipe 12, the gas outlet of described nitrogen compressor 2 is connected with joint 6；In described knockout drum 3
High level sensor 14 and low liquid level sensor 15 are provided with, high level sensor 14 is located at the lower section of inlet 8, described height
Liquid level sensor 14, low liquid level sensor 15 and high-pressure pump 10 are connected with controller.
Described controller is PLC, and controller is connected with natural gas compressor 1 and nitrogen compressor 2, passes through control
Device processed can control the startup or closing of natural gas compressor 1 and nitrogen compressor 2, facilitate operating personnel to operate, with automatic
The characteristics of change degree is high.
The course of work of the present invention is as follows：Via controller control nitrogen compressor 2 starts, the output high pressure of nitrogen compressor 2
Nitrogen enters in gas well 4 through joint 6, and high pressure nitrogen acts on liquid levels in gas well 4, liquid and overstocks day below liquid
Right gas enters in knockout drum 3 through delivery pipe 7, inlet 8, and liquid enters in knockout drum 3 under gravity, works as liquid
Position reaches on high level sensor 14 that high level sensor 14 sends electric signal to controller, and controller control high-pressure pump 10 is opened
Dynamic, high-pressure pump 10 is by liquid evacuation in knockout drum 3, to avoid the full liquid of the storage of knockout drum 3, when liquid level is in low
During liquid level sensor 15, the electrical signal of low liquid level sensor 15 is to controller, and controller continues to control nitrogen compressor work, real
Now continuous kill-job；And the natural gas produced then enters in natural gas compressor 1 through gas outlet 11, natural gas compressor 1 will be opened
Become high pressure-temperature natural gas after the natural gas boosting of extraction, supercharging, when high pressure-temperature natural gas enters backward in blast pipe 12
Cooling water is passed through in chuck 13, cooling water absorbs natural gas heat, so as to reduce the heat of natural gas carrying, it is ensured that final to receive
Natural gas after collection can be used directly, and realizes and continuously taps natural gas, without follow-up cooling process, greatly improve natural
Gas production efficiency.
It can thus be appreciated that the arrangement achieves continuous pressurized gas lift water pumping gas production, no matter many deep gas wells can be exploited,
Further reduce the loss that the stopping production of gas-producing well hydrops is caused.In addition the arrangement achieves closed gas production, water-producing gas well is increased
Gas production.
