Background technology
At present, natural gas has turned into the indispensable fuel of people, and gas well depth is deeper, and the water of deposition is got in gas well Greatly, natural gas pile things on causes the fluid-carrying capability of gas-producing well to decline in underwater, can not 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 The characteristics of big extraction amount of workload is small be present again in artificial extract.
In recent years, oil gas field has carried out multinomial water drainage-gas recovery technology research and experiment, the master of water-producing gas well water pumping gas production at present To use foam drainage gas recovery technique.Although foam drainage gas recovery technique is gradually improved and ripe, due to the distribution of gas well, 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 Pressure unbalanced phenomena be present 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 is preferable, in order to give full play to the high pressure of new Brought-in Gas Wells, the superiority of high production capacity, in combination with yard process characteristic, opens Open up high-pressure air source gas well gas and lift drainage gas production technology research, achieve certain effect.But the number of high-pressure air source well at present Measure 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 uses 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, increase gas production input cost.
Utility model content
A kind of the shortcomings that the purpose of this utility model is to overcome prior art, there is provided compact-sized, continuous supercharging of realization Gaslift water pumping gas production, reduce loss caused by gas-producing well hydrops stops production, improve water-producing gas well gas production, production efficiency it is high it is complete from Dynamic water pumping gas production equipment.
The purpose of this utility model is achieved through the following technical solutions:A kind of Full-automatic drainage gas recovery facility, it includes Controller, natural gas compressor, nitrogen compressor, knockout drum and the closure being fixedly arranged at the top of gas well, described is close Capping top is provided with joint and connects the centre bore of gas well, and delivery pipe, the bottom extension of delivery pipe are installed with centre bore In in gas well, the upper end of delivery pipe is extended outside gas well, and inlet and row are provided with the side wall of described knockout drum Liquid mouth, inlet are connected with delivery pipe upper end, and high-pressure pump is connected with leakage fluid dram, outlet is provided with the top of knockout drum Mouthful, the arrival end of gas outlet and natural gas compressor connects, and is provided with blast pipe on natural gas compressor, is cased with pressing from both sides on blast pipe Set, the gas outlet of described nitrogen compressor is connected with joint;Be provided with described knockout drum high level sensor and Low liquid level sensor, described high level sensor, low liquid level sensor and high-pressure pump are connected with controller.
Described controller is connected with natural gas compressor and nitrogen compressor.
Described controller is PLC.
The vertical setting of described delivery pipe.
Described high level sensor is located at the lower section of inlet.
The utility model has advantages below:The utility model realizes continuous pressurized gas lift water pumping gas production, reduces gas-producing well Loss, raising water-producing gas well gas production, production efficiency are high caused by hydrops stops production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure, 1- natural gas compressors, 2- nitrogen compressors, 3- knockout drums, 4- gas wells, 5- closures, 6- joints, 7- delivery pipes, 8- inlets, 9- leakage fluid drams, 10- high-pressure pumps, 11- gas outlets, 12- blast pipes, 13- chucks, 14- high levels pass Sensor, 15- low liquid level sensors.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to It is lower described:
As shown in figure 1, a kind of Full-automatic drainage gas recovery facility, it includes controller, natural gas compressor 1, nitrogen compression Machine 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 connected Ventilate the centre bore of well 4, be installed with delivery pipe 7 in centre bore, 7 vertical setting of delivery pipe, the bottom of delivery pipe 7 extends gas In well 4, the upper end of delivery pipe 7 is extended outside gas well 4, and inlet 8 and row are provided with the side wall of described knockout drum 3 Liquid mouth 9, inlet 8 are 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 Gas outlet 11 is equipped with, gas outlet 11 is connected with the arrival end of natural gas compressor 1, and blast pipe is provided with natural gas compressor 1 12, chuck 13 is cased with blast pipe 12, and the gas outlet of described nitrogen compressor 2 is connected with joint 6;Described knockout drum High level sensor 14 and low liquid level sensor 15 are provided with 3, high level sensor 14 is located at the lower section of inlet 8, described High level sensor 14, low liquid level sensor 15 and high-pressure pump 10 be 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, and have automatic The characteristics of change degree is high.
The course of work of the present utility model is as follows:Via controller control nitrogen compressor 2 starts, the output of nitrogen compressor 2 High pressure nitrogen enters in gas well 4 through joint 6, and high pressure nitrogen acts on liquid levels in gas well 4, liquid and overstocks below liquid Natural gas through delivery pipe 7, inlet 8 enter knockout drum 3 in, liquid under gravity enter knockout drum 3 in, When liquid level reaches on high level sensor 14, high level sensor 14 sends electric signal to controller, controller control high-pressure pump 10 start, and high-pressure pump 10 is by liquid evacuation in knockout drum 3, to avoid the full liquid of the storage of knockout drum 3, at liquid level When low liquid level sensor 15, to controller, controller continues to control nitrogen compressor work the electrical signal of low liquid level sensor 15 Make, realize continuous kill-job;And the natural gas produced then enters in natural gas compressor 1 through gas outlet 11, natural gas compressor 1 The natural gas boosting that will be produced, become high pressure-temperature natural gas after supercharging, when high pressure-temperature natural gas enters in blast pipe 12 Cooling water is passed through in backward chuck 13, cooling water absorbs natural gas heat, so as to reduce the heat of natural gas carrying, ensure that most Natural gas after collecting eventually can be used directly, and realizes and continuously taps natural gas, without follow-up cooling process, greatly improves Natural gas extraction efficiency.
It can thus be appreciated that the arrangement achieves continuous pressurized gas lift water pumping gas production, no matter more deep gas wells can be exploited, Further reduce loss caused by gas-producing well hydrops stops production.In addition the arrangement achieves closed gas production, water-producing gas well is increased Gas production.
