Problems solved by technology

During the oil testing process, ground test measurement technology is used to obtain data such as production, pressure, temperature, etc., which provides a strong basis for the further development and utilization of oil and gas fields. To burn the natural gas produced in the formation, but the blowing and burning in this way will cause noise pollution and serious heat radiation, which will have a great impact on the surrounding environment
[0005] To sum up, it can be seen that during the development and production of oil and gas fields, unusable blow-off gas is generated in multiple stages and needs to be combusted. Electricity and other supporting facilities are not perfect, so it is of great significance to develop a safe and reliable, low noise and light pollution, strong fuel gas adaptability, and easy to install on a skid.

Embodiment 1

[0032] combine Figure 1 to Figure 6 , an integrated flare system, including a fire cabinet mechanism 1, a conveying mechanism 2 and a control mechanism 3. Firebox mechanism 1 comprises firebox tube 11, is provided with ground burner 12, ground igniter 13 and ground flame monitor 14 in the middle part of firebox tube 11, is provided with high-pressure nozzle 15 in the top of firebox tube 11, and firebox An overhead igniter 16 and an overhead flame detector 17 are arranged above the cylinder 11 .

[0033] The conveying mechanism 2 comprises a first main air pipe 21, a pressure gauge 22 and a flame arrester 23 are arranged on the first main air pipe 21, a low-pressure air pipe 24 and a high-pressure air pipe 25 are connected on the gas outlet of the first main air pipe 21, and a There is a first air pipe control assembly 26, and the air outlet of the low pressure air pipe 24 is connected with the ground burner 12. The high-pressure air pipe 25 is provided with a second air pip...

Embodiment 2

[0047] Taking the combustion treatment of associated gas produced in the oilfield development and production stage as an example to illustrate the integrated flare system, the diameter of the fire tank 11 of an integrated flare system is 0.8m, the height of the cylinder is 6.5m, and the working pressure of the low-pressure gas pipe is 0.6 kPa-15kPa, the processing capacity can reach 600m 3 / d; the working pressure of the high-pressure air pipe is 0-800kpa, and the processing capacity can reach 48000m 3 / d.

[0048] Under normal production conditions, the associated gas produced in the oil field basically enters the ground burner 12 through the low-pressure gas pipe and burns inside the fire cabinet 11. The flame does not emerge from the fire cabinet 11, so that the airtight combustion inside the cylinder is realized, and the elevated flare is in a standby state.

[0049] When the amount of waste gas discharged under emergency working conditions exceeds the combustion load req...

Embodiment 3

[0051] Under normal production conditions, it is difficult to use exhaust gas to be discharged into the exhaust gas pipeline. The pressure is judged in the control cabinet 31 .

[0052] When the pressure is 0.6kpa-15kpa, the ground torch combustion load is met, and the control cabinet 31 transmits the signal to quickly open the first low-pressure solenoid valve 262 and the ground igniter 13, and the exhaust gas passes through the flame arrester 23, the first low-pressure stop valve 261, the second A low-pressure solenoid valve 262 and a second low-pressure shut-off valve 263 enter the ground burner 12 and spray out with pressure, and are ignited by the ground igniter 13, and the ground flame monitor 14 closes the ground igniter 13 after detecting the flame.

[0053] Exhaust gas is sealed and burned inside the fire cabinet tube 11, and the flame does not emerge from the fire cabinet tube 11, so the heat radiation is less. Among them, the ground burner 12 adopts a multi-point i...

Description

technical field [0001] The invention relates to the field of safety and environmental protection, in particular to an integrated flare system. Background technique [0002] In the process of oil extraction, some combustible gas will be produced, which is called oil-associated gas. The pressure of associated gas is generally between 1-2psi (6.894-13.788kPa), and the main component is methane, usually containing a large amount of ethane and heavy hydrocarbon components. Through years of technological development, the recovery rate of associated gas in my country's oilfields has been greatly improved, but there are still some oilfields or a small number of blocks that have failed to achieve closed gathering and transportation due to various reasons, such as some remote scattered wells, newly opened wells, test production wells, Pipeless wells, wells with high casing pressure in small fault block oilfields, etc., are difficult to recycle because of poor casing gas, small and sca...
