Description

Technical Field

[0001] This application relates to the field of natural gas extraction and transportation technology, specifically a mixed-transportation booster device for natural gas wells. Background Technology

[0002] During the extraction and production of natural gas wells, as extraction activities continue, the formation pressure gradually decreases. This directly leads to the natural gas pressure at the wellhead failing to meet the standard requirements for long-distance transportation or subsequent processing. To ensure that natural gas can be transported smoothly and efficiently to its destination for further processing and utilization, blending and boosting units have become an indispensable key piece of equipment in the natural gas extraction process.

[0003] Currently, natural gas boosting technology mainly adopts two methods: single-stage compression and multi-stage compression. Single-stage compression cannot meet the high-pressure requirements, while traditional multi-stage compression devices that can provide high pressure have prominent problems such as large size and complex system, as well as low efficiency. They also cause significant energy loss during energy conversion, resulting in high equipment operating costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a mixed-transportation booster device for natural gas wells. It achieves efficient step-by-step boosting through multi-stage booster components. At the same time, the gradient shrinkage design of the cross-sectional area of ​​the gradually narrowing channel significantly improves the gas kinetic energy conversion efficiency. Combined with the advantages of curved guide vanes to optimize the airflow path and reduce energy loss, it solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a mixed-transportation booster device for natural gas wells, comprising an integrated housing, with a multi-stage booster assembly disposed inside the integrated housing. The multi-stage booster assembly includes a first booster tank, a second booster tank, and a third booster tank. The outer sides of the first, second, and third booster tanks are all fixedly connected to the inner side of the integrated housing. A tapered channel is fixedly connected to the outer sides of the first, second, and third booster tanks. Multiple circumferentially arrayed curved guide vanes are fixedly connected to the inner side of each pressure tank. Booster pumps are fixedly installed on the outer sides of the first, second, and third pressure tanks. Pressure transmitters are fixedly installed on the outer sides of the three tapered channels. Electrically controlled valves are fixedly installed on the outer sides of the three tapered channels. Connecting pipes are provided on the outer sides of the three tapered channels. The first, second, and third pressure tanks are connected in series through the connecting pipes. A controller is fixedly installed on the outer side of the integrated housing.

[0006] The above solution, through the integrated design of the integrated shell and multi-stage pressurization components, effectively reduces the overall volume of the device compared to traditional multi-stage compression equipment. The multi-stage pressurization components, consisting of the first, second, and third pressurization tanks, combined with the pressurization pump, can achieve efficient pressurization in stages. At the same time, the synergistic effect of the curved guide vanes and the gradually narrowing channel can optimize the gas flow rate and pressure distribution. Subsequently, the pressure transmitter and electrically controlled valves facilitate real-time monitoring and precise pressure control, improving the stability and reliability of the device operation.

[0007] Furthermore, connecting pipes are fixedly installed on the outer sides of both the second and third pressurization tanks, and the two ends of the connecting pipes are fixedly connected to the tapered channel and the connecting pipes through flanges.

[0008] The above scheme, with the connection of the connecting pipe and the connecting pipeline and the use of flange connection, not only facilitates the connection and disassembly between the pressure tanks of each stage in the multi-stage pressure boosting assembly, making maintenance and repair easier, but also ensures the tightness of the connection, prevents gas leakage, and guarantees the efficient operation of the pressure boosting process.

[0009] Furthermore, sealing gaskets are fixedly installed at both ends of the connecting pipe.

[0010] The above solution enhances the sealing of pipe connections by installing sealing gaskets, effectively preventing gas leakage during transmission, reducing energy consumption, and improving the overall operating efficiency and safety of the device.

[0011] Furthermore, a sleeve is fixedly connected to the outside of the first pressurization tank, an air inlet pipe is fixedly connected to the outside of the sleeve, and two filter plates are fixedly connected to the inside of the air inlet pipe.

[0012] The above solution effectively filters impurities in natural gas by setting two filter plates, preventing impurities from entering the multi-stage booster assembly, avoiding wear on internal components, extending the service life of the device, and ensuring the purity of the booster gas.

[0013] Furthermore, the third pressurization tank is provided with an exhaust pipe on its outer side, and one end of the exhaust pipe is fixedly connected to the converging channel through a flange.

[0014] The above solution connects the gas outlet pipe to the flange of the tapered channel, ensuring that the pressurized natural gas can be output smoothly, providing a stable gas source for subsequent transportation and processing. The connection method is reliable and easy to disassemble and maintain.

[0015] Furthermore, a cooling fan is fixedly installed on the upper side of the integrated housing, and two sets of symmetrical cooling grooves are opened on the outer side of the integrated housing.

[0016] The above solution, by combining a cooling fan and a heat sink, can dissipate the heat generated during the operation of the device in a timely manner, effectively reducing the internal temperature of the integrated casing, avoiding the impact of excessive temperature on the performance and service life of each component, and ensuring the continuous and stable operation of the device.

[0017] Furthermore, the cross-sectional area of ​​each of the tapered channels gradually decreases along the gas flow direction.

[0018] The above-mentioned scheme, with its gradually decreasing cross-sectional area along the gas flow direction, can accelerate and pressurize the gas. Combined with multi-stage pressurization components, it can further enhance the overall pressurization effect and improve the working efficiency of the device.

[0019] Furthermore, the surface of each of the curved guide vanes is covered with a wear-resistant ceramic coating.

[0020] Through the above-mentioned solution, the wear-resistant ceramic coating on the surface of the curved guide vanes enhances the wear resistance of the vanes, reduces the wear caused by the high-speed flow of natural gas, extends the service life of the vanes, and at the same time ensures the guiding effect of gas in the pressurization tank, thereby improving the stability and reliability of the device operation.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This natural gas well mixed-transport booster unit significantly reduces the size of the device through the integrated design of an integrated shell and multi-stage booster components, solving the problem of the large size of traditional multi-stage compression equipment. Then, the multi-stage booster components work with the booster pump to achieve efficient step-by-step boosting. At the same time, the gradient shrinkage design of the cross-sectional area of ​​the gradually narrowing channel significantly improves the gas kinetic energy conversion efficiency. Combined with the curved guide vanes to optimize the airflow path and reduce energy loss, the pressure transmitter and the electronically controlled valve work together to optimize the pressure distribution and achieve precise control.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a natural gas well mixed-transport booster device includes an integrated housing 1. A multi-stage booster assembly 2 is disposed inside the integrated housing 1. The integrated design of the integrated housing 1 and the multi-stage booster assembly 2 effectively reduces the overall volume of the device compared to traditional multi-stage compression equipment. The multi-stage booster assembly 2 includes a first booster tank 201, a second booster tank 202, and a third booster tank 203. The multi-stage booster assembly 2, composed of the first booster tank 201, the second booster tank 202, and the third booster tank 203, in conjunction with a booster pump 204, can achieve efficient boosting at each stage. The outer sides of the first booster tank 201, the second booster tank 202, and the third booster tank 203 are all fixedly connected to the inner side of the integrated housing 1. A tapered channel 3 is fixedly connected to the outer sides of the first booster tank 201, the second booster tank 202, and the third booster tank 203. Multiple circumferentially arrayed curved guide vanes 205 are fixedly connected to the inner side of each of the three pressure tanks 201, 202, and 203. The curved guide vanes 205 and the tapered channel 3 work together to optimize the gas flow rate and pressure distribution. The surface of each curved guide vane 205 is covered with a wear-resistant ceramic coating. The wear-resistant ceramic coating on the surface of the curved guide vanes 205 enhances the wear resistance of the vanes, reduces the wear of the vanes caused by the high-speed flow of natural gas, extends the service life of the vanes, and at the same time ensures the guiding effect of the gas in the pressurization tank, improving the stability and reliability of the device operation. A booster pump 204 is fixedly installed on the outer side of each of the three pressurization tanks 201, 202, and 203. A pressure transmitter 4 is fixedly installed on the outer side of each of the three tapered channels 3. An electric control valve 5 is fixedly installed on the outer side of each of the three tapered channels 3. The pressure transmitter 4 and the electric control valve 5 facilitate real-time monitoring and precise control of the pressure, improving the stability and reliability of the device operation.

[0032] Please see Figure 2 and Figure 4 Three tapered channels 3 are connected by connecting pipes 6 on their outer sides. The first pressurization tank 201, the second pressurization tank 202, and the third pressurization tank 203 are connected in series via the connecting pipes 6. A controller 15 is fixedly installed on the outer side of the integrated housing 1. Connecting pipes 7 are fixedly installed on the outer sides of the second pressurization tank 202 and the third pressurization tank 203. Both ends of the connecting pipes 6 are fixedly connected to the tapered channels 3 and the connecting pipes 7 via flanges. The connection between the connecting pipes 7 and the connecting pipes 6, using a flange connection method, not only facilitates the connection and disassembly between the pressurization tanks of each stage in the multi-stage pressurization assembly 2, making maintenance and repair easier, but also ensures the tightness of the connection, prevents gas leakage, and ensures the efficient operation of the pressurization process. Both ends of the connecting pipes 6 are fixedly installed with sealing gaskets 8. The sealing gaskets 8 further enhance the sealing of the pipe connection, effectively preventing gas leakage during transmission, reducing energy consumption, and improving the overall operating efficiency and safety of the device.

[0033] Please see Figure 1 , Figure 2 and Figure 5 A sleeve 9 is fixedly connected to the outer side of the first booster tank 201, and an air inlet pipe 10 is fixedly connected to the outer side of the sleeve 9. Two filter plates 11 are fixedly connected to the inner side of the air inlet pipe 10. By setting two filter plates 11, impurities in the natural gas can be effectively filtered, preventing impurities from entering the multi-stage booster assembly 2, avoiding wear on internal components, extending the service life of the device, and ensuring the purity of the boosted gas. An air outlet pipe 12 is provided on the outer side of the third booster tank 203, and one end of the air outlet pipe 12 is fixedly connected to the converging channel 3 through a flange. The connection between the air outlet pipe 12 and the flange of the converging channel 3 ensures that the boosted natural gas can be smoothly output, providing a stable gas source for subsequent transportation and processing. The connection method is reliable and convenient. For disassembly and maintenance, a cooling fan 13 is fixedly installed on the upper side of the integrated housing 1, and two sets of symmetrical heat dissipation slots 14 are opened on the outer side of the integrated housing 1. By setting the combination of cooling fan 13 and heat dissipation slots 14, the heat generated during the operation of the device can be dissipated in time, effectively reducing the internal temperature of the integrated housing 1, avoiding the impact of excessive temperature on the performance and service life of various components, and ensuring the continuous and stable operation of the device. The cross-sectional area of ​​each tapering channel 3 gradually decreases along the gas flow direction. The design of the tapering channel 3 gradually decreasing along the gas flow direction can accelerate and pressurize the gas. In conjunction with the multi-stage pressurization component 2, the overall pressurization effect is further improved, and the working efficiency of the device is increased.

[0034] This embodiment of a natural gas well mixed-transport booster device significantly reduces the device size through the integrated design of an integrated housing 1 and a multi-stage booster assembly 2, thus improving the problem of the large size of traditional multi-stage compression equipment. Then, the multi-stage booster assembly 2, together with the booster pump 204, achieves efficient step-by-step boosting. At the same time, the gradient shrinkage design of the cross-sectional area of ​​the gradually narrowing channel 3 significantly improves the gas kinetic energy conversion efficiency. Combined with the curved guide vanes 205, the airflow path is optimized and energy loss is reduced. Then, the pressure transmitter 4 and the electrically controlled valve 5 work together to optimize the pressure distribution and achieve precise control.

[0035] It should be noted that the controller 15 is electrically connected to the booster pump 204, pressure transmitter 4 and electrically controlled valve 5 inside the equipment, which facilitates real-time monitoring and precise pressure control, and improves the stability and reliability of the device operation.

[0036] The working principle of the above embodiment is as follows: Natural gas enters the first pressurization tank 201 through the inlet pipe 10 and is filtered by the filter plate 11. Under the action of the pressurization pump 204 and the curved guide vane 205, it is initially pressurized. Then, the gas enters the second pressurization tank 202 through the converging channel 3 and the connecting pipe 6, and is pressurized again by the pressurization pump 204 and the curved guide vane 205. Then, the gas enters the third pressurization tank 203 in the same way to complete the final pressurization. In the whole process, the converging channel 3 uses the change of cross-sectional area to assist the gas to accelerate the pressurization. The pressure transmitter 4 monitors the pressure in real time. The electronically controlled valve 5 accurately adjusts the gas flow and pressure according to the monitoring data to ensure stable output pressure. At the same time, the cooling fan 13 and the heat dissipation tank 14 work continuously to ensure that the device operates at a suitable temperature. Finally, the pressurized natural gas is output through the outlet pipe 12, realizing efficient mixed transmission and pressurization, and solving various problems existing in traditional technology.
