Description

Technical Field

[0001] This utility model relates to the field of infrared spectroscopy measurement technology, specifically to a spectral logging gas analysis device. Background Technology

[0002] Well logging gas refers to the various gaseous components carried by the drilling fluid returning from the bottom of the well during the drilling process. These gaseous components are detected and analyzed using gas logging technology to determine the presence and properties of oil and gas reservoirs. Well logging gas detection generally employs spectral analysis equipment. Infrared spectroscopy is used to analyze and identify the molecules of a substance. A beam of infrared rays of different wavelengths is irradiated onto the molecules of the substance; certain specific wavelengths of infrared rays are absorbed, forming the infrared absorption spectrum of that molecule, thereby enabling qualitative and quantitative analysis of the substance's type. The purposes of well logging gas detection are threefold: first, to directly discover oil and gas reservoirs; second, to monitor and provide early warning of toxic and harmful gases; and third, to discover non-hydrocarbon gas deposits.

[0003] Based on the above, the inventors have discovered the following problems: In actual use, current spectral analysis devices do not have cleaning components and cannot clean the gas cell. When cleaning manually, due to the small internal space of the gas cell, it is difficult to reach some corners and hidden parts, resulting in incomplete cleaning. The dirt and dust remaining on the inner wall of the gas cell will scatter or absorb infrared light, weaken the light signal intensity, and affect the detection sensitivity.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a spectral logging gas analysis device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a spectral logging gas analysis device to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A spectroscopic logging gas analysis device includes a spectrometer body and a cleaning assembly. The cleaning assembly is disposed outside the spectrometer body. The spectrometer body is used to analyze logging gas, and the cleaning assembly is used to clean the gas pool. The spectrometer body includes a housing with a circular hole on one side of the front of the housing. The gas pool is threaded into the circular hole, and one end of the gas pool is located inside the housing. An optical lens is disposed inside the one end of the gas pool. The cleaning assembly includes a pair of connecting plates, which are installed on the outer side of the housing. A cleaning cylinder and a drying cylinder are respectively connected between the pair of connecting plates on the side away from the housing. Both the cleaning cylinder and the drying cylinder have cylinder caps at their upper ends. Both cylinder caps have mounting holes inside. A first sleeve and a second sleeve are respectively connected to the inside of the two mounting holes via bearings. One end of the first sleeve extends into the interior of the cleaning cylinder, and a cleaning cotton is connected to the outside of the first sleeve. The surface of the first sleeve in contact with the cleaning cotton has several micropores.

[0008] Furthermore, the cleaning cotton has a hollow ring-shaped cross-section, and a groove is provided at the bottom end of the cleaning cotton. The inner wall of the groove is in clearance fit with the outer wall of the optical lens located in the gas pool.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, since the cross-section of the cleaning cotton is hollow and annular, that is, the cleaning cotton has holes inside, the inner wall of the holes is connected to the outer wall of the first sleeve, and the contact surface between the first sleeve and the inner wall of the holes has micropores, it is easy for water or cleaning agents such as anhydrous ethanol to enter the interior of the first sleeve and wet the cleaning cotton through the micropores, thereby cleaning the interior of the gas pool. By opening a groove at the bottom of the cleaning cotton, and the inner wall of the groove is in clearance fit with the outer wall of the optical lens, the cleaning cotton can accurately fit close to the outer wall of the optical lens in the gas pool, thereby cleaning dust, stains and other impurities on the outer wall of the optical lens and ensuring the optical performance of the optical lens.

[0010] Furthermore, the bottom end of the second sleeve is connected to an air blowing head, and the surface of the air blowing head is provided with several micro air holes.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that, through the combined use of the second sleeve, the blowing head and the micro air hole, high-purity nitrogen enters the interior of the second sleeve, then enters the interior of the blowing head through the second sleeve, and is discharged through the micro air hole, thus drying the gas pool placed in the drying cylinder after cleaning.

[0012] Furthermore, both the cleaning cylinder and the drying cylinder are equipped with negative pressure suction pumps at their bottom ends. The air inlet ends of the two negative pressure suction pumps extend through the cleaning cylinder and the drying cylinder respectively into the interior, and the air inlet ends of the two negative pressure suction pumps are connected to a negative pressure plate.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of a negative pressure pump and a negative pressure plate (two of each), when the gas pool is placed in the cleaning or drying cylinder, the side of the optical lens outside the gas pool is in contact with the negative pressure plate. By activating the negative pressure pump, the space between the negative pressure plate and the optical lens is drawn to negative pressure, thus fixing the gas pool. In practical applications, the negative pressure plate must be made of a soft, elastic, and smooth material to ensure full contact with the surface of the optical lens and uniform dispersion of the adsorption force. At the same time, the negative pressure must be precisely controlled and adjusted according to the material, size, thickness, and other parameters of the lens to avoid excessive or insufficient adsorption force. The adsorption and release of the lens must be slow and steady to prevent damage to the lens due to impact.

[0014] Furthermore, both the first and second sleeves are fitted with worm gears on the outside of the inner part of the cylinder cover. Both cylinder covers are fitted with worms near the worm gears on the inside. The worms mesh with the worm gears, and the two ends of the worms are connected to the inner wall of the cylinder cover through bearings. Both cylinder covers are fitted with micro motors on the outer wall, and the output ends of the two micro motors are fixedly connected to the two worms respectively.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of a micro motor, a worm gear, and a worm, with two of each, after the gas pool is placed inside the cleaning cylinder, the micro motor at the top cover of the cleaning cylinder is started to drive the worm to rotate. Under the meshing action of the worm and the worm gear, the first sleeve rotates, causing the first sleeve to rotate together with the cleaning cotton to clean the inner wall of the gas pool and the internal optical lens. After cleaning, the gas pool is removed and placed in the drying cylinder. The micro motor at the top cover of the drying cylinder is started to drive the worm to rotate, and under the meshing action of the worm and the worm gear, the second sleeve rotates, causing the second sleeve to rotate together with the air blowing head to blow air and dry the inner wall of the gas pool and the internal optical lens.

[0016] Furthermore, the gas pool is a hollow cylindrical shape and is transparent. One end of the gas pool has an installation groove, and the optical lens is disposed in the installation groove. The outer wall of the optical lens is fixedly connected to the inner wall of the installation groove. A sealing cap is threadedly connected to the end of the gas pool away from the optical lens. The sealing cap is connected to an inlet pipe and an outlet pipe on the side away from the optical lens. The inlet pipe and the outlet pipe are arranged sequentially from top to bottom.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, since the sealing cap is threadedly connected to the gas pool, when the sealing cap is unscrewed, one end of the gas pool is exposed. By setting up an inlet pipe and an outlet pipe, the logging gas can enter the gas pool through the inlet pipe and exit the gas pool through the outlet pipe, thereby realizing continuous detection of the logging gas. At the same time, since the gas pool is transparent, it can ensure that infrared light and other light rays can pass through smoothly.

[0018] Furthermore, the housing has an infrared light source connected to the inner wall opposite to the optical lens, an interferometer connected to the inner wall of the housing on the side of the gas pool, and a detector located inside the housing opposite to the interferometer. The housing also has an analog-to-digital converter and a digital-to-analog converter located inside the housing near the detector. An amplifier and a filter are located inside the housing on the side of the analog-to-digital converter and the digital-to-analog converter. The front of the housing has a display screen located away from the circular hole.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that, through the coordinated use of infrared light source, interferometer, detector, amplifier, filter, analog-to-digital converter, digital-to-analog converter and display screen, the infrared light source provides the light source required for analysis, the interferometer processes the light to generate interference fringes, the detector converts the light signal into an electrical signal, the analog-to-digital converter and digital-to-analog converter realize the signal conversion, the amplifier and filter amplify and filter the signal, and finally the analysis results are displayed intuitively on the display screen.

[0020] Furthermore, a square groove is provided on one side of the back of the housing, and a heat dissipation grid and a polypropylene filter membrane are arranged sequentially from the outside to the inside of the square groove.

[0021] The beneficial effect of adopting the above-mentioned further solution is that by setting a heat dissipation grid and a polypropylene filter membrane from the outside to the inside of the square groove, with the polypropylene filter membrane close to the inside of the housing and the heat dissipation grid away from the inside of the housing, the heat generated by the spectrometer body during operation is dissipated through the heat dissipation grid, and the polypropylene filter membrane, which has good air permeability and a certain filtering effect, can block external dust, particles and other impurities from entering the spectrometer body while dissipating heat, thus protecting the electronic components and optical parts inside the spectrometer body.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The gas pool of this spectral logging gas analysis device is connected to the circular hole threaded on the housing, facilitating the installation, disassembly, and replacement of the gas pool. When the gas pool needs cleaning, it is removed from the housing. Since the sealing cap is threaded to the gas pool, when the sealing cap is unscrewed, one end of the gas pool is exposed. Then, the cover of the cleaning cylinder is opened, and the gas pool is placed inside. The cover of the cleaning cylinder is then closed. When the gas pool is placed inside the cleaning cylinder, the side of the optical lens outside the gas pool is in contact with the negative pressure plate inside the cleaning cylinder. By starting the negative pressure pump at the bottom of the cleaning cylinder, the space between the negative pressure plate and the optical lens is drawn to negative pressure, thus fixing the gas pool. The micro motor at the top cover of the cleaning cylinder is started, driving the worm gear to rotate. Under the meshing action of the worm gear and worm wheel, the first sleeve rotates, causing the first sleeve and the cleaning cotton to rotate together. Through the first sleeve, water or cleaning agents such as anhydrous ethanol enter the interior of the first sleeve and wet the cleaning cotton through the micropores. This process involves using cleaning cotton to clean the inside of the gas pool. A groove is created at the bottom of the cleaning cotton, and the inner wall of the groove fits snugly against the outer wall of the optical lens. This allows the cleaning cotton to precisely adhere to the outer wall of the gas pool, effectively removing dust, stains, and other impurities from the outer wall of the optical lens, ensuring its optical performance. After cleaning, the gas pool is removed and placed inside a drying cylinder. A negative pressure pump at the bottom of the drying cylinder is activated, drawing negative pressure into the space between the negative pressure plate and the optical lens, thus securing the gas pool. High-purity nitrogen enters the second sleeve through the second sleeve, then through the air blower, and exits through the micro-hole. A micro motor at the top of the drying cylinder is activated, driving the worm gear to rotate. The meshing of the worm gear and worm wheel causes the second sleeve to rotate, causing it and the air blower to rotate together, drying the inner wall of the cleaned gas pool and the internal optical lens inside the drying cylinder.

The spectrometer body 1 includes a housing 11, with a circular hole on one side of the front of the housing 11. The gas pool 12 is threaded into the circular hole, and one end of the gas pool 12 is located inside the housing 11. An optical lens 13 is disposed inside the one end of the gas pool 12. The cleaning component 2 includes a pair of connecting plates 21, which are installed on the outer side of the housing 11. A cleaning cylinder 22 and a drying cylinder 23 are respectively connected between the pair of connecting plates 21 on the side away from the housing 11. The upper end of each of the two sleeves 24 is provided with a cylinder cover 24. The inside of each cylinder cover 24 is provided with an installation hole. The inside of the two installation holes is connected to a first sleeve 25 and a second sleeve 27 respectively through bearings. One end of the first sleeve 25 extends into the inside of the cleaning cylinder, and a cleaning cotton 26 is connected to the outside of the first sleeve 25. Several micro-holes are provided on the surface of the first sleeve 25 that contacts the cleaning cotton 26. The gas pool 12 is threadedly connected to the round hole on the housing 11, which facilitates the installation, disassembly and replacement of the gas pool 12. When the gas pool 12 needs to be cleaned, it is removed from the housing 11. The micro-holes on the contact surface between the first sleeve 25 and the cleaning cotton 26 allow water or cleaning agents such as anhydrous ethanol to enter the inside of the first sleeve 25 and wet the cleaning cotton 26 through the micro-holes, thereby cleaning the inside of the gas pool 12 with the cleaning cotton 26.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5This utility model provides a technical solution: the cleaning cotton 26 has a hollow ring-shaped cross-section, and a groove is provided at the bottom end of the cleaning cotton 26. The inner wall of the groove is in clearance fit with the outer wall of the optical lens 13 located in the gas pool 12. The bottom end of the second sleeve 27 is connected to an air blowing head 28. The surface of the air blowing head 28 is provided with several micro air holes. Negative pressure suction pumps 212 are installed at the bottom ends of the cleaning cylinder 22 and the drying cylinder 23. The air inlet ends of the two negative pressure suction pumps 212 extend through the cleaning cylinder 22 and the drying cylinder 23 respectively and are connected to a negative pressure plate. The first sleeve 25 and the second sleeve 27 are both fitted with worm gears 29 on the outside of the cylinder cover 24. The inside of the two cylinder covers 24 is provided with worms near the worm gears 29. 210, the worm 210 and the worm wheel 29 mesh with each other, and the two ends of the worm 210 are connected to the inner wall of the cylinder cover 24 through bearings. Micro motors 211 are installed on the outer walls of both cylinder covers 24, and the output ends of the two micro motors 211 are fixedly connected to the two worms 210 respectively. By opening a groove at the bottom of the cleaning cotton 26, and with the inner wall of the groove fitting with the outer wall of the optical lens, the cleaning cotton 26 can accurately adhere to the outer wall of the optical lens 13 located in the gas pool 12, thereby cleaning dust, stains, and other impurities on the outer wall of the optical lens 13, ensuring the optical performance of the optical lens 13. Through the combined use of the second sleeve 27, the air blowing head 28, and the micro air holes, high-purity nitrogen enters the interior of the second sleeve 27, and then... The tube 27 enters the air blowing head 28 and discharges through micro-holes, drying the gas pool 12 placed in the drying cylinder 23 after cleaning. This is achieved through the combined use of a negative pressure pump 212 and two negative pressure plates. When the gas pool 12 is placed in the cleaning cylinder 22 or the drying cylinder 23, the side of the optical lens 13 outside the gas pool 12 is in contact with the negative pressure plate. By activating the negative pressure pump 212, negative pressure is drawn into the contact space between the negative pressure plate and the optical lens 13, thus fixing the gas pool 12. In practical applications, the negative pressure plate must be made of a soft, elastic, and smooth material to ensure full contact with the surface of the optical lens 13 and uniform dispersion of the adsorption force. Precise control is also required. The negative pressure is adjusted according to the material, size, and thickness of the lens to avoid excessive or insufficient adsorption. Adsorption and release of the lens should be slow and steady to prevent damage from impact. After the gas pool 12 is placed inside the cleaning cylinder 22, the micro motor 211 at the top cover 24 of the cleaning cylinder 22 is activated to drive the worm gear 210 to rotate. The meshing of the worm gear 210 and the worm wheel 29 causes the first sleeve 25 to rotate, allowing it to rotate together with the cleaning cotton 26. This cleans the inner wall of the gas pool 12 and the internal optical lens 13. After cleaning, the gas pool 12 is removed and placed inside the drying cylinder 23. The micro motor 211 at the top cover 24 of the drying cylinder 23 is then activated to drive the worm gear 210 to rotate.The second sleeve 27 rotates under the meshing action of the worm gear 210 and worm wheel 29, causing the second sleeve 27 to rotate together with the air blowing head 28, thus blowing air to dry the inner wall of the gas pool 12 and the internal optical lens 13.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-5 This utility model provides a technical solution: the gas pool 12 is a hollow cylindrical shape and is transparent. An installation groove is provided at one end of the gas pool 12, and an optical lens 13 is disposed within the installation groove. The outer wall of the optical lens 13 is fixedly connected to the inner wall of the installation groove. A sealing cap 14 is threadedly connected to the end of the gas pool 12 away from the optical lens 13. An inlet pipe 15 and an outlet pipe 16 are connected to the side of the sealing cap 14 away from the optical lens 13. The inlet pipe 15 and the outlet pipe 16 are arranged sequentially from top to bottom. An infrared light source 17 is connected to the inner wall of the housing 11 opposite to the optical lens 13. An interferometer 18 is connected to the inner wall of the housing 11 on one side of the gas pool 12. A detector 19 is provided inside the housing 11 opposite to the interferometer 18. An analog-to-digital converter 112 and a digital-to-analog converter 11 are provided inside the housing 11 near the detector 19. 3. Inside the housing 11, an amplifier 110 and a filter 111 are located on one side of the analog-to-digital converter 112 and digital-to-analog converter 113. A display screen is located on the front of the housing 11 away from the circular hole. A square groove is opened on one side of the back of the housing 11. A heat dissipation grid and a polypropylene filter membrane are arranged sequentially from the outside to the inside of the square groove. Through the coordinated use of the infrared light source 17, interferometer 18, detector 19, amplifier 110, filter, analog-to-digital converter 112, digital-to-analog converter 113 and display screen, the infrared light source 17 provides the light source required for analysis, the interferometer 18 processes the light to generate interference fringes, the detector 19 converts the light signal into an electrical signal, the analog-to-digital converter 112 and digital-to-analog converter 113 realize the signal conversion, the amplifier 110 and filter 111 amplify and filter the signal, and finally the analysis results are displayed intuitively on the display screen.

[0035] Specifically, the working principle of this spectral logging gas analysis device is as follows: During use, an inlet pipe 15 and an outlet pipe 16 are installed, connecting the inlet and outlet gas paths to the inlet and outlet pipes 15 and 16 respectively. This allows the logging gas to enter the gas pool 12 through the inlet pipe 15 and exit through the outlet pipe, achieving continuous detection of the logging gas. The device utilizes an infrared light source 17, an interferometer 18, a detector 19, an amplifier 110, a filter, an analog-to-digital converter 112, a digital-to-analog converter 113, and a display screen. The infrared light source 17 provides the necessary light source for analysis; the interferometer 18 processes the light to generate interference fringes; the detector 19 converts the light signal into an electrical signal; and the analog-to-digital converter 112 and digital-to-analog converter 113... 113 realizes signal conversion, amplifier 110 and filter 111 amplify and filter the signal, and finally display the analysis results intuitively on the display screen. At the same time, since the gas pool 12 is transparent, it can ensure that infrared light and other light can pass through smoothly. When the gas pool 12 needs to be cleaned, it is removed from the housing 11. Since the sealing cover 14 is threaded to the gas pool 12, when the sealing cover 14 is unscrewed, one end of the gas pool 12 is exposed. Then, the cylinder cover 24 of the cleaning cylinder 22 is opened, the gas pool 12 is placed inside the cleaning cylinder 22, and then the cylinder cover 24 of the cleaning cylinder 22 is closed. When the gas pool 12 is placed inside the cleaning cylinder 22, the side of the optical lens 13 located outside the gas pool 12 is in contact with the negative pressure plate inside the cleaning cylinder 22. The negative pressure suction pump 212 at the bottom of the cleaning cylinder 22 draws negative pressure into the contact space between the negative pressure plate and the optical lens 13, thus fixing the gas pool 12. The micro motor 211 at the top cover 24 of the cleaning cylinder 22 is activated, driving the worm gear 210 to rotate. The meshing action of the worm gear 210 and the worm wheel 29 causes the first sleeve 25 to rotate, allowing it to rotate together with the cleaning cotton 26. Water or cleaning agents, such as anhydrous ethanol, enter the first sleeve 25 through the first sleeve 25 and wet the cleaning cotton 26 through micropores, thus cleaning the interior of the gas pool 12. A groove is formed at the bottom of the cleaning cotton 26, and the inner wall of the groove fits the outer wall of the optical lens, allowing the cleaning cotton 26 to clean precisely. The gas tank 12 is positioned close to the outer wall of the optical lens 13 to clean dust, stains, and other impurities, ensuring the optical performance of the lens 13. After cleaning, the gas tank 12 is removed and placed inside the drying cylinder 23. By activating the negative pressure pump 212 at the bottom of the drying cylinder 23, the space between the negative pressure plate and the optical lens 13 is evacuated to negative pressure, thus fixing the gas tank 12. High-purity nitrogen gas enters the second sleeve 27 through the second sleeve 27 and then the air blowing head 28, exiting through the micro-hole. The micro motor 211 at the top cover 24 of the drying cylinder 23 is activated, driving the worm gear 210 to rotate.The second sleeve 27 rotates under the meshing action of the worm gear 210 and worm wheel 29, causing the second sleeve 27 to rotate together with the air blowing head 28, thus blowing air to dry the inner wall of the gas pool 12 and the internal optical lens 13 placed in the drying cylinder 23 after cleaning.
