Detailed Embodiment

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] The integrated device for buffering produced liquid, such as Figure 1 and Figure 2As shown in the figure, it includes a base 1. On the base 1, a produced liquid buffer tank 3 is installed through a support 2. On the base 1, an operation platform 4 located at the top of the produced liquid buffer tank 3 is installed through a ladder 11. Guardrails are provided around the operation platform 4. A manhole 13 is opened at the top of the produced liquid buffer tank 3. Inside the produced liquid buffer tank 3, a man ladder 14 matching the manhole 13 is provided. At the upper part of one end of the produced liquid buffer tank 3, a liquid inlet pipe 5 communicating with its interior is connected. At the top of the produced liquid buffer tank 3, an air outlet pipe 9 communicating with its interior is connected. At the bottom of the produced liquid buffer tank 3, a produced water output pipe 6 communicating with its interior is connected. At the bottom of the produced liquid buffer tank 3, a produced water transportation pipe 8 communicating with its interior is connected. At the bottom of the produced liquid buffer tank 3, a maintenance drain pipe 7 communicating with its interior is connected. At a position corresponding to the liquid inlet pipe 5 inside the produced liquid buffer tank 3, a buffer partition 12 is provided. On the tank wall of the produced liquid buffer tank 3, two liquid level gauges 15 and two tuning fork switches 16 are provided. Control valves are installed on the liquid inlet pipe 5, the air outlet pipe 9, the produced water output pipe 6, the maintenance drain pipe 7, and the produced water transportation pipe 8. An electrical control cabinet 10 is installed on the base 1. The electrical control cabinet 10 is electrically connected to the liquid level gauges 15, the tuning fork switches 16, and the control valves.

[0021] The working principle of the present utility model is as follows: When the gas-liquid mixture enters the produced liquid buffer tank 3 from the liquid inlet pipe 5, after passing through the energy absorber, it sprays onto the buffer partition 12. Due to the pressure reduction and the diffusion effect, the natural gas dissolved in the liquid is freed. Using the gravity effect, the gas and liquid are initially separated. Due to the difference in specific gravity, the liquid is at the bottom of the tank and the gas is at the top of the tank and is discharged from the air outlet pipe 9. During normal operation, due to the continuous inlet of the medium, the pressure in the produced liquid buffer tank 3 is always relatively stable, and the liquid uniformly enters the next system through the produced water output pipe 6 at the bottom of the buffer tank.

[0022] At the same time, the liquid level gauges 15 and the tuning fork switches 16 are used to measure the liquid level height in the produced liquid buffer tank 3. When the liquid level height in the produced liquid buffer tank 3 is higher than the limit height of the controller, the electrical control cabinet 10 controls the valve on the produced water output pipe 6 to accelerate the liquid discharge so as to lower the liquid level in the produced liquid buffer tank 3; when the liquid level height in the produced liquid buffer tank 3 is lower than the limit height of the controller, the electrical control cabinet 10 controls the valve on the produced water output pipe 6 to slow down the liquid discharge so as to raise the liquid level in the produced liquid buffer tank 3.

[0023] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
