Description

Technical Field

[0001] The utility model relates to the technical field of oil field production, in particular to a sound insulation and noise reduction device used in oil field production sites. Background Art

[0002] Oilfield CO2 injection production involves injecting CO2 into the bottom of a production well, shutting the well down for a period of time to allow the CO2 to seep into the oil layer, and then reopening the well for production. The CO2 enhancement process utilizes CO2 to replenish formation energy. When dissolved in crude oil, CO2 expands the crude oil volume, reduces viscosity, and enhances fluidity. When dissolved in water, it becomes slightly acidic, reacting with the formation matrix and increasing formation permeability, thereby reducing steam injection pressure and improving fluid supply capacity.

[0003] At oilfield liquid carbon dioxide injection sites, CO2 evacuation must be performed before and after injection. Directly discharging the gas from the pipeline into the air during evacuation can result in excessive noise at the exhaust port, sometimes reaching 120 decibels, due to the high pressure of the CO2. Furthermore, the sudden drop in pressure at the exhaust port causes the CO2 to condense into dry ice, blocking the exhaust line. Conventional sound insulation and noise reduction devices use baffles for soundproofing. This condensed CO2, in the form of dry ice, can clog the device and prevent proper CO2 evacuation. Therefore, the development of a sound insulation and noise reduction device for oilfield production sites is urgently needed.

[0004] The utility model patent with patent number CN201922343518.6 and publication (announcement) number CN211448086U discloses a sound insulation and noise reduction device for oilfield ground construction, comprising a base, a baffle fixedly connected to the top of the base, pointed rods fixedly connected to the four corners of the bottom of the base, a first rectangular groove with openings on the front and rear sides on one side of the baffle, and a first sound-absorbing cotton bonded and fixed to the inner wall of one side of the first rectangular groove, a honeycomb sound-absorbing cotton fixedly connected to one side of the first sound-absorbing cotton, and a metal sound-absorbing panel fixedly connected to the side of the honeycomb sound-absorbing cotton away from the first sound-absorbing cotton. The utility model has a reasonable design, has sound insulation and noise reduction functions, and has a buffering function, which can effectively alleviate the impact force generated by collisions with external personnel or other mobile equipment. While reducing the risk of damage to the baffle through buffering protection, it can also reduce damage to other equipment and items and alleviate injuries caused by collisions with personnel, making it convenient to use.

[0005] The utility model patent with patent number CN202020874733.9 and publication (announcement) number CN212322626U discloses a mobile noise reduction device for high-noise equipment in oil fields, comprising multiple bases and multiple frames, the frames being fixedly mounted on the upper end of the bases, the front and rear end side walls of the bases being respectively fixedly mounted with multiple support mechanisms, the bottom of the bases being fixedly mounted with locking universal wheels, the left and right end side walls of the bases being respectively fixedly mounted with first and second connecting blocks, the same connecting mechanism being provided between adjacent first and second connecting blocks, and a steel plate and a first sound insulation board being fixedly mounted within the frame. This utility model achieves the purpose of preliminary noise absorption by the honeycomb silencer, further noise absorption by the sound-absorbing cotton, and then noise reflection by the first sound insulation board, thereby achieving a better sound insulation effect, through the coordinated use of the honeycomb silencer, the sound-absorbing cotton, and the first sound insulation board.

[0006] The utility model patent with patent number CN201720303649.X and publication (announcement) number CN206616717U discloses an oilfield sound-absorbing structural device, comprising a crossbar disposed at the bottom, a slot disposed at the top of the crossbar, an expansion bolt connected to the ground disposed at the bottom of the slot, a bracket assembly disposed within the slot, and a sound-absorbing assembly disposed between two adjacent bracket assemblies. The bracket assembly comprises a rod, a slot disposed at the front and rear end surfaces of the rod, the slot vertically penetrating the rod, and a cover plate disposed at the front and rear end surfaces of the rod. The cover plate has a core embedded in the slot, a bolt is disposed between the two cover plates, the bolt passes through the rod, the width of the cover plate is greater than the width of the rod, and a mounting slot for mounting the sound-absorbing assembly is formed between the cover plate and the rod. The sound-absorbing assembly comprises sound-absorbing cotton and soundproof wall panels disposed at the front and rear sides of the sound-absorbing cotton. The sound-absorbing assembly is easy to construct and can effectively achieve sound insulation.

[0007] While all of the above existing technologies can achieve the technical effect of soundproofing and reducing noise during oilfield production, they all rely on a combination of soundproof panels, soundproof walls, and sound-absorbing cotton. Their noise reduction effectiveness is limited, and they cannot effectively prevent blockage in vent lines. Therefore, they are not suitable for CO2 venting operations. Therefore, we propose a soundproofing and noise reduction device for oilfield production sites. Utility Model Content

[0016] Beneficial effects

[0017] The utility model provides a sound insulation and noise reduction device for oil field production sites. It has the following beneficial effects:

[0018] (1) The sound insulation and noise reduction device used in oil field production sites is provided with a damping device that can close the inside of the condenser bag by setting a damping device in the bending channel of the condenser bag. As the exhaust pipe discharges more gas into the condenser bag, the closed area at the lower end of the condenser bag will be pressurized as the gas increases. As the exhaust pipe continues to inflate the lower end of the internal channel of the condenser bag, the damping device will be pushed open.

At this time, the lower end of the condenser bag is partially discharged with the gas, and the damping device will once again close the internal bending channel of the condenser bag to avoid excessive noise when the exhaust pipe continues to exhaust gas outward. At the same time, the external gas collides with the rotating upward internal channel and gradually diffuses upward, further playing a noise reduction effect, and playing a noise reduction effect on the exhaust of the exhaust pipe.

[0019] (2) The sound insulation and noise reduction device used in oil field production sites arranges the connecting component at the inner lower end of the condensation bag, and performs multi-point fixed docking at the connection between the condensation bag and the exhaust pipe, thereby improving the fixing effect between the exhaust pipe and the condensation bag.

[0020] (3) The sound insulation and noise reduction device used in oil field production sites is provided with a connecting tube for convenient connection through a connecting protrusion on the condensing bag. When the condensing bag is put on the exhaust pipe, it can be quickly docked and fixed, thereby achieving a fixing effect between the exhaust pipe and the condensing bag.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0034] Example 1: A sound insulation and noise reduction device for oil field production sites, such as Figures 1-4 As shown, it includes a processing box 1, the interior of the processing box 1 is injected with liquid carbon dioxide, the outside of the processing box 1 is provided with an air inlet pipe 2 connected to the interior of the processing box 1, the top of the processing box 1 is connected to an exhaust pipe 3 for exhausting carbon dioxide, and the interior of the processing box 1 is provided with a noise reduction duct 12 connecting the air inlet pipe 2 and the exhaust pipe 3, wherein the internal diameter of the noise reduction duct 12 gradually increases from small to large, and the shape of the noise reduction duct 12 is spirally wound upward, specifically as shown in FIG. Figure 2 As shown;

[0035] Inside the processing box 1, a noise reduction duct 12 is installed, rotating upward from bottom to top and gradually increasing in diameter. Inside the duct, a vertically rotating spiral structure is incorporated. As the fluid within the duct passes through this spiral structure, it undergoes shear deformation, effectively breaking up noise waves. Furthermore, the duct's smaller diameter at the bottom increases the velocity and pressure of the fluid upon entering, effectively collecting and directing incoming noise waves.

[0036] When noise passes through the duct, it will cause interference and affect people's auditory perception. By using the noise reduction duct 12, the spiral structure inside the duct can break the noise wave and reduce its transmission, so that the impact of the noise is reduced. The external gas collides with the rotating upward internal channel and gradually diffuses upward, which has a noise reduction effect.

[0037] The top of the exhaust pipe 3 is connected to the condensation bag 4 through a connecting component. The interior of the condensation bag 4 is provided with a bending channel. The interior of the bending channel is provided with a damping device that can close the interior of the condensation bag 4. A filter screen 5 is installed on the top of the condensation bag 4. When the exhaust pipe 3 is in the exhaust state, the damping device will open the bending channel inside the condensation bag 4, and the external liquid carbon dioxide gas will contact and collide with the damping device inside the condensation bag 4. Combined with the increase in the internal pressure of the condensation bag 4, the liquid dioxide gas will condense into particles and be discharged outward.

[0038] The damping device includes a magnetic plate 1 6 and a magnetic plate 2 7 located on both sides of the bending channel inside the condensation bag 4, and magnetic adsorption is performed between the magnetic plate 1 6 and the magnetic plate 2 7.

[0039] Example 2: Based on Example 1, Figure 4-Figure 5 As shown, connecting protrusions 8 are installed at the edge of the outer wall of the exhaust pipe 3 , and the connecting protrusions 8 are evenly spaced and distributed around the outer side of the exhaust pipe 3 .

[0040] The connecting component includes a docking plate 9 located inside the lower end of the condenser bag 4. The front end of each docking plate 9 is connected to a docking ring 10. The condenser bag 4 is fixed to the exhaust pipe 3 by clamping the docking ring 10 with the corresponding connecting protrusion 8 on the outside of the exhaust pipe 3. By arranging the connecting component at the inner lower end of the condenser bag 4, the connection between the condenser bag 4 and the exhaust pipe 3 is fixed and docked at multiple points, thereby improving the fixing effect between the exhaust pipe 3 and the condenser bag 4. At the same time, the connecting component is wrapped inside the condenser bag 4 and is not exposed, which has an aesthetic effect.

[0041] Example 3: Based on Example 1, Figure 6As shown, a connecting protrusion 8 is installed at the edge of the outer wall of the exhaust pipe 3, and the connecting protrusions 8 are evenly spaced around the outer side of the exhaust pipe 3. The connecting assembly includes a connecting tube 11 embedded in a circle around the outer cylindrical edge of the condensation bag 4. The connecting tube 11 is a metal circular tube, and one end of the connecting protrusion 8 extends outward through the corresponding connecting tube 11 to the outside of the condensation bag 4.

[0042] By providing a connecting tube 11 for convenient connection through the connecting protrusion 8 on the condenser bag 4, the condenser bag 4 can be quickly docked and fixed when it is put on the exhaust pipe 3, thereby achieving a fixing effect between the exhaust pipe 3 and the condenser bag 4.

[0043] The working principle of the present invention is as follows: a damping device that can close the interior of the condensation bag 4 is provided in the bending channel of the condensation bag 4. As the exhaust pipe 3 discharges more gas into the condensation bag 4, the closed area at the lower end of the condensation bag 4 will be pressurized as the gas increases. As the exhaust pipe 3 continues to inflate the lower end of the internal channel of the condensation bag 4, the damping devices will be pushed open. At the moment the internal bending channel of the condensation bag 4 is pushed open, the gas is discharged through the connecting hole of the filter 5. At this time, a part of the gas is discharged from the lower end of the condensation bag 4, and the damping device will once again close the internal bending channel of the condensation bag 4 to avoid excessive noise when the exhaust pipe 3 continues to exhaust gas outward, thereby reducing the noise of the exhaust of the exhaust pipe 3. At the same time, the external gas collides with the rotating upward internal channel and gradually diffuses upward, further reducing the noise.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
