Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, and in particular to a natural gas storage tank for oil extraction. Background Technology

[0002] Oilfield natural gas storage tanks are sealed containers used for the temporary or long-term storage of natural gas associated with oil extraction. They are key facilities in the natural gas gathering, processing, and export processes. Their main function is to balance fluctuations in natural gas production and export volume, ensuring the stable operation of the extraction, processing, and transportation systems. Oilfield natural gas storage tanks are used at oilfield and natural gas extraction sites, gas gathering stations, and processing plants for the temporary or long-term storage of natural gas associated with or specifically extracted during extraction. They balance fluctuations in production and export volume, ensure the stable operation of the gathering and transportation system, and also provide storage support for subsequent processes such as LNG transportation.

[0003] When workers need to store natural gas, they input the natural gas into the storage tank so that the storage tank can store the natural gas. However, during the use of existing natural gas storage tanks, due to seasonal factors, the temperature difference between the surface and the interior of the storage tank can become too large, which can lead to cracks on the surface of the storage tank due to excessive stress concentration. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the surface of natural gas storage tanks in the prior art cracks due to excessive stress concentration, and to propose a natural gas storage tank for oil extraction.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a natural gas storage tank for oil extraction, comprising a storage tank, a support mounted on the surface of the storage tank, a temperature control device provided on the surface of the storage tank, the temperature control device including a water guide pipe, the water guide pipe being rotatably connected to the interior of the storage tank, a water storage block fixedly connected to the top end of the water guide pipe, a nozzle fixedly connected to the lower surface of the water storage block, the nozzle being located above the storage tank, a water pump rotatably connected to the bottom end of the water guide pipe, a water storage tank fixedly connected to the lower surface of the water pump, a heating wire fixedly connected to the interior of the water storage tank, a drive assembly provided on the surface of the storage tank, the drive assembly including a drive motor fixedly connected to the surface of the storage tank, a rotating wheel fixedly connected to the drive end of the drive motor, the drive motor being able to cooperate with the rotating wheel to drive the rotating wheel to rotate, the outlet pipe and the water pump being installed underground, the water pump being existing technology, and an external pipe mounted on the surface of the water storage tank.

[0006] Preferably, a drive wheel is fixedly connected to the surface of the water guide pipe, and the drive wheel is meshed with the surface of the rotating wheel. The drive wheel can cooperate with the water guide pipe to support the drive wheel, and the drive wheel can cooperate with the rotating wheel to adjust the rotation of the water guide pipe.

[0007] Preferably, the surface of the storage container is provided with a collecting device, the collecting device including a frame, the frame being fixedly connected to the surface of the storage container, the frame being located inside the support, and the frame being able to cooperate with the storage container to achieve the purpose of fixing the frame.

[0008] Preferably, the surface of the frame is provided with a water channel, which is located above the water storage tank. The water channel can cooperate with the frame to guide the flow of temperature-controlled water.

[0009] Preferably, a return water pipe is fixedly connected between the frame and the water storage tank. The return water pipe is located on both sides of the water pump. The return water pipe can cooperate with the frame and the water storage tank to guide the temperature-controlled water back to the water storage tank.

[0010] Preferably, the return water pipe has a water guide groove inside, which is connected to the inside of the water storage tank. The water guide groove can cooperate with the return water pipe to facilitate the circulation of temperature-controlled water. The inner wall of the frame is provided with an inclined plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a temperature control device, when workers need to control the surface temperature of the natural gas storage tank, they can choose whether to turn on the heating wire according to the season. The workers start the water pump, which draws temperature-controlled water from inside the storage tank. The temperature-controlled water enters the water guide pipe and then the water storage block. The water storage block guides the temperature-controlled water to flow out from the nozzle, which sprays the temperature-controlled water onto the surface of the storage tank. The workers start the drive motor, which drives the rotating wheel. The rotating wheel adjusts the drive wheel, which drives the water guide pipe. The water guide pipe adjusts the rotation of the water storage block and the nozzle, and the nozzle sprays the temperature-controlled water evenly onto the storage tank. By setting up the temperature control device, the surface temperature of the natural gas storage tank can be effectively controlled, avoiding a large temperature difference between the surface and the interior of the natural gas storage tank, thereby reducing the problem of cracking on the surface of the natural gas storage tank due to excessive stress concentration.

[0012] In this invention, by setting up a collection device, when workers need to collect temperature-controlled water, the temperature-controlled water on the surface of the storage tank will flow towards the frame due to gravity and the guidance of the tank wall. The water in the water inlet trough collects the temperature-controlled water, which then converges in the water inlet trough. The inclined plate on the inner wall of the frame guides the temperature-controlled water to the return pipe. The water guide trough inside the return pipe guides the temperature-controlled water into the storage tank. By setting up a collection device, temperature-controlled water can be effectively collected, avoiding the waste of a large amount of water resources when the temperature control device is used, thereby improving the water-saving performance of the temperature control device.
