Detailed Description
The technical scheme of the invention will be fully and clearly described below with reference to the accompanying drawings.
The gas field gas collecting and boosting station energy circulating device comprises a water jacket heating furnace 1, a compressor filtering separator 2, a compressor 3, a compressor rear heat exchanger 4 and a circulating water booster pump 5, wherein a low-pressure gas pipeline 6 is connected with the compressor filtering separator 2, the compressor filtering separator 2 is connected with the compressor 3, the compressor 3 is communicated with the compressor rear heat exchanger 4, the compressor 3 is used for applying work to boosting gas, the temperature is increased while the pressure of the boosting gas is increased, the boosting gas reaches the compressor rear heat exchanger 4, the compressor rear heat exchanger 4 is connected with the water jacket heating furnace 1 through the circulating water booster pump 5, and one end of the water jacket heating furnace 1 is communicated with the compressor rear heat exchanger 4.
The water jacket heating furnace 1 is connected with the outlet of the rear heat exchanger 4 of the compressor, heating medium is desalted water, and the circulating water booster pump 5 is utilized to realize that low-temperature water absorbs heat from the pressurization of the low-pressure gas well to the release of heat of the high-pressure gas well water jacket heating furnace 1.
The water jacket heating furnace 1 is connected with a high-pressure gas well, and heating and throttling of the high-pressure gas well are realized by using the water jacket heating furnace 1.
The compressor 3 and the pressurized high-temperature gas are connected with a compressor heat exchanger.
Example A
The low-pressure gas firstly enters the compressor filter separator 2 through the low-pressure gas pipeline 6, and enters the compressor 3 for pressurization after gas-liquid separation. The compressor 3 works on the pressurized gas, the pressure of the pressurized gas is increased, the temperature is increased at the same time, the heat is exchanged between the high-temperature pressurized gas and low-temperature circulating water by the heat exchanger 4 after the compressor is removed, and the low-temperature pressurized gas is directly conveyed outwards after the heat exchange; after the temperature of the circulating water is increased, the circulating water booster pump 5 is used for boosting, the water jacket heating furnace 1 is used for heating gas well gas and gas after primary throttling in the water jacket heating furnace 1, so that the temperature of the gas well gas after primary throttling is higher than the hydrate forming temperature, and a pipeline is not blocked. After the water jacket heating furnace 1 exchanges heat with gas coming from a gas well, low-temperature circulating water returns to the heat exchanger 4 behind the compressor, and the pressurized gas exchanges heat with the circulating water again, so that the effective utilization of the energy in the station is realized.
Example B
According to the method of the invention, HYSYS software is adopted for modeling analysis, and the method is exemplified as follows: when the inlet pressure of the compressor 3 is 1MPa and the weather body is pressurized to 4.5MPa, the outlet gas of the compressor 3 is cooled to 35 ℃, the cooling water is increased from 30 ℃ to 80 ℃, and the circulating water is required to be about 111.9t/d; the circulating water after heating is heated and throttled to come gas from the high-pressure gas well before throttling, so that the requirement that the high-pressure gas well throttles from 25MPa to 4.5MPa every day is met, and the temperature of the circulating water is reduced to 30 ℃ from 80 ℃. After the conversion, the conversion is carried out, in theory, the low-pressure air of 1 square meter per pressurizing can meet the high-pressure air throttling requirement of about 1.4 square meters.
