Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically to an infrared spectral gas detection device for well logging gas measurement. 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: Current infrared spectroscopy gas detection devices are not convenient for rapid heat dissipation and only use natural heat dissipation methods, such as relying on the metal material of the instrument shell for natural heat dissipation. When the instrument is running under high load for a long time, natural heat dissipation cannot meet the needs of rapid heat dissipation, causing heat to accumulate inside the infrared spectroscopy gas detection device and making it difficult to dissipate quickly. This can easily cause the infrared spectroscopy gas detection device to overheat, affecting the detection accuracy and instrument life. Utility Model Content

[0004] The purpose of this invention is to provide an infrared spectroscopy gas detection device for well logging gas measurement, so as to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] An infrared spectral gas detection device for well logging gas detection includes an infrared spectral detector body, a first heat dissipation component, and a second heat dissipation component. The first heat dissipation component is disposed on opposite sides of the infrared spectral detector body, and the second heat dissipation component is disposed below the infrared spectral detector body. The infrared spectral detector body is used to detect well logging gas. The first heat dissipation component is used to dissipate heat from the infrared spectral detector body, and the second heat dissipation component is used to dissipate heat from the first heat dissipation component. The first heat dissipation component includes a pair of side seats, each of which has a partition connected inside. The top and bottom surfaces of the partitions form a first chamber and a second chamber with the top and bottom interior surfaces of the side seats, respectively. The first chamber has a first cooling pipe inside, and a plurality of first heat dissipation fins are connected to the outside of the first cooling pipe. The infrared spectral detector body includes a housing, the outer sides of which are fixedly connected to one side of the pair of side seats. One end of each of the plurality of first heat dissipation fins extends through the side seats and the housing into the interior of the housing.

[0007] Furthermore, the first heat dissipation fin has a circular hole inside, the outer wall of the first cooling pipe is fixedly connected to the inner wall of the circular hole, the second chamber has a second cooling pipe inside, a connecting pipe is connected between one end of the first cooling pipe and the second cooling pipe, and the first cooling pipe and the second cooling pipe are respectively connected to an inlet pipe and an outlet pipe at the end away from the connecting pipe.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by setting a first heat dissipation fin, one end of the first heat dissipation fin extends into the interior of the housing, thereby facilitating heat dissipation inside the housing. Heat accumulates on the first heat dissipation fin, and through the coordinated use of the first cooling pipe, the connecting pipe, the inlet pipe, and the outlet pipe, the first cooling pipe and the second cooling pipe are connected by the connecting pipe, and the inlet pipe and the outlet pipe are respectively set, a circulation channel for the coolant is formed, which can continuously remove the heat on the first heat dissipation fin, ensuring effective heat dissipation of the infrared spectrometer body.

[0009] Furthermore, a mounting hole is provided on one side of the partition, and a micro pump is installed inside the mounting hole. The liquid inlet of the micro pump is connected to the end of the water outlet pipe away from the second cooling pipe, and the liquid outlet of the micro pump is connected to the end of the water inlet pipe away from the first cooling pipe.

[0010] The beneficial effect of adopting the above-mentioned further solution is that by opening mounting holes in the partition, it is convenient to install the micro pump. When the micro pump is started, the micro pump pumps the coolant inside the second cooling pipe into the first cooling pipe, so that the coolant inside the second cooling pipe circulates through the outlet pipe, the micro pump, the inlet pipe, the first cooling pipe, and the connecting pipe, continuously carrying away the heat of the first heat dissipation fins and improving the heat dissipation efficiency of the first heat dissipation fins for the infrared spectrometer body.

[0011] Furthermore, both the second cooling pipe and the interior of the second chamber are filled with coolant.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, since the interior of the second chamber is filled with coolant, when the coolant circulates into the interior of the second cooling pipe, the coolant inside the second chamber exchanges heat with the coolant inside the second cooling pipe, thereby cooling the coolant inside the second cooling pipe.

[0013] Furthermore, the second heat dissipation component includes a base, the top surface of which is fixedly connected to the bottom surface of the housing, and the two sides of the base are respectively fixedly connected to the side of the side seat near the housing. Square chambers are formed on both sides of the interior of the base. A plurality of second heat dissipation fins are connected inside the square chambers. The plurality of second heat dissipation fins are arranged sequentially from front to back. The outer side of the plurality of second heat dissipation fins is fixedly connected to the inner wall of the square chamber, and one side of the plurality of second heat dissipation fins extends through the base and the side seat into the interior of the second chamber.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by opening square chambers on both sides of the base, and connecting the interior of the square chambers to the second heat dissipation fins, the second heat dissipation fins extend into the interior of the second chambers, increasing the contact area with the coolant in the second chambers, thereby dissipating heat and cooling the coolant in the second chambers, and thus ensuring the normal operation of the first heat dissipation component.

[0015] Furthermore, each of the second heat dissipation fins has a pair of air flow holes inside. Both the second heat dissipation fins and the first heat dissipation fins are made of brass. The front sides of the base have mounting slots in the square cavity. Cooling fans are installed inside the two mounting slots. The back of the base has an exhaust vent opposite to the cooling fans.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by opening air flow holes on the second heat dissipation fin, the air flow holes inside the second heat dissipation fin facilitate air flow. When the cooling fan is working, it accelerates the air flow speed between the second heat dissipation fin, which can quickly remove the heat on the second heat dissipation fin and discharge it to the outside of the base through the exhaust port.

[0017] Furthermore, a gas pool is provided on one side of the interior of the housing. An air inlet pipe and an air outlet pipe are connected to the front of the gas pool. The air inlet pipe and the air outlet pipe are arranged sequentially from top to bottom. Both the air inlet pipe and the air outlet pipe extend through the housing to the outside at the end away from the gas pool. An optical lens is connected inside the gas pool at the end away from the air inlet pipe. The gas pool is transparent.

[0018] The beneficial effect of adopting the above-mentioned further solution is that 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.

[0019] Furthermore, the housing has an infrared light source connected to the inner wall opposite the optical lens, an interferometer connected to the inner wall of the housing on one side of the gas pool, and a detector located inside the housing opposite the interferometer. Inside the housing, an amplifier, a filter, an analog-to-digital converter, and a digital-to-analog converter are arranged sequentially from right to left near the detector. The front of the housing has a display screen.

[0020] The beneficial effects of adopting the above-mentioned further scheme are that, through the coordinated use of an 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 infrared light passes through the interferometer and is modulated into interference light, which carries information about all wavelengths of the light source. When the interference light passes through a gas cell containing the gas to be measured, the gas molecules absorb infrared light of specific wavelengths, causing a change in the intensity of the interference light. The detector converts the optical signal into an electrical signal, the analog-to-digital converter and digital-to-analog converter perform signal conversion, the amplifier and filter amplify and filter the signal, and finally, the analysis results are displayed intuitively on the display screen.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This infrared spectral gas detection device for well logging gas measurement, by setting a first heat dissipation fin, one end of which extends into the interior of the housing, facilitates heat dissipation from the interior of the housing. Heat accumulates on the first heat dissipation fin. Since both the second cooling pipe and the second chamber are filled with coolant, the first and second cooling pipes are connected by a connecting pipe. The ends of the first and second cooling pipes furthest from the connecting pipe are respectively connected to an inlet pipe and an outlet pipe, and one end of the inlet pipe and the outlet pipe are respectively connected to the outlet and inlet of the micro pump. When the micro pump is started... When the micro pump is in operation, it pumps the coolant from the second cooling pipe into the first cooling pipe, causing the coolant inside the second cooling pipe to circulate through the outlet pipe, micro pump, inlet pipe, first cooling pipe, and connecting pipe. This continuously removes heat from the first heat dissipation fins, improving the heat dissipation efficiency of the first heat dissipation fins on the infrared spectrometer. When the coolant circulates into the second cooling pipe, the coolant inside the second chamber exchanges heat with the coolant inside the second cooling pipe, thereby cooling the coolant inside the second cooling pipe and improving the heat dissipation efficiency of the first heat dissipation fins on the infrared spectrometer.

[0030] 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.

[0031] Please see Figures 1-5 This utility model provides a technical solution: the second heat dissipation component 3 includes a base 31, the top surface of the base 31 is fixedly connected to the bottom surface of the housing 11, and the two sides of the base 31 are respectively fixedly connected to the side of the side seat 21 near the housing 11. Square chambers are formed on both sides of the interior of the base 31, and a plurality of second heat dissipation fins 32 are connected inside the square chambers. The plurality of second heat dissipation fins 32 are arranged sequentially from front to back, and the outer sides of the plurality of second heat dissipation fins 32 are fixedly connected to the inner wall of the square chambers.

[0032] 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.

[0033] Please see Figures 1-5 This utility model provides a technical solution: a gas pool 12 is provided on one side of the interior of the housing 11. An air inlet pipe and an exhaust pipe are connected to the front of the gas pool 12, arranged sequentially from top to bottom. Both the air inlet pipe and the exhaust pipe extend through the housing 11 to the outside at the end furthest from the gas pool 12. An optical lens 13 is connected inside the gas pool 12 at the end furthest from the air inlet pipe. The gas pool 12 is transparent. An infrared light source 14 is connected to the inner wall of the housing 11 opposite to the optical lens 13. An interferometer 15 is connected to the inner wall of the housing 11 on one side of the gas pool 12. A detector 16 is provided inside the housing 11 opposite to the interferometer 15. An amplifier and a filter are arranged sequentially from right to left inside the housing 11 near the detector 16. The device includes an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC). A display screen is located on the front of the housing 11. The logging gas input and output pipes are connected to the inlet and outlet pipes of the gas tank 12, respectively. These pipes allow the logging gas to enter the gas tank 12 through the inlet pipe and exit through the outlet pipe, enabling continuous monitoring of the logging gas. Once the logging gas enters the gas tank 12 through the inlet pipe, an infrared light source 14 provides the necessary light for analysis. The infrared light is modulated into interference light by an interferometer 15. This interference light carries information about all wavelengths of the light source. When the interference light passes through the gas tank 12 containing the gas to be tested, the gas molecules absorb specific wavelengths of infrared light, causing a change in the intensity of the interference light. A detector 16 converts the optical signal into an electrical signal. The ADC and DAC perform signal conversion, and an amplifier and filter amplify and filter the signal. Finally, the analysis results are displayed visually on the screen. The transparent nature of the gas tank 12 ensures that infrared light and other light rays can pass through smoothly.

[0034] Specifically, the working principle of this infrared spectroscopy gas detection device for logging gas measurement is as follows: In use, the logging gas input pipeline and logging gas output pipeline are first connected to the inlet and outlet pipes of the gas pool 12, respectively. When the logging gas enters the gas pool 12 through the inlet pipe, the infrared light source 14 provides the light source required for analysis. The infrared light passes through the interferometer 15 and is modulated into interference light, which carries information about all wavelengths of the light source. When the interference light passes through the gas pool 12 containing the gas to be measured, the gas molecules absorb infrared light of a specific wavelength, causing a change in the intensity of the interference light. The infrared spectroscopy detector body 1 is a SE6030 model, based on Fourier transform infrared spectroscopy technology, employing high-temperature in-situ sampling and analysis technology. It can directly analyze the sample gas, reducing process losses and secondary reactions of pollutants. It can perform rapid on-site qualitative and quantitative detection of organic and inorganic gases in the logging gas. By setting a first heat dissipation fin 24, one end of which extends into the interior of the housing 11, heat dissipation inside the housing 11 is facilitated. Coolant accumulates on fins 24. Since both the second cooling pipe 27 and the second chamber 26 are filled with coolant, the first cooling pipe 25 and the second cooling pipe 27 are connected by a connecting pipe 28. At the ends of the first cooling pipe 25 and the second cooling pipe 27 furthest from the connecting pipe 28, they are respectively connected to an inlet pipe 210 and an outlet pipe 211. One end of the inlet pipe 210 and the outlet pipe 211 are respectively connected to the outlet and inlet of the micro pump 29. When the micro pump 29 is started, it pumps the coolant from the second cooling pipe 27 into the first cooling pipe 25, causing the coolant in the second cooling pipe 27 to flow through the outlet pipe 210. 11. The micro pump 29, water inlet pipe 210, first cooling pipe 25, and connecting pipe 28 circulate and continuously remove heat from the first heat dissipation fins 24, improving the heat dissipation efficiency of the first heat dissipation fins 24 on the infrared spectrometer body 1. When the coolant circulates into the second cooling pipe 27, the coolant in the second chamber 26 exchanges heat with the coolant in the second cooling pipe 27, thereby cooling the coolant in the second cooling pipe 27 and improving the heat dissipation efficiency of the first heat dissipation fins 24 on the infrared spectrometer body 1. Square chambers are opened on both sides of the base 31, and the interior of the square chambers... The second heat dissipation fin 32 is connected and extends into the second chamber 26, increasing the contact area with the coolant in the second chamber 26, thereby dissipating heat and cooling the coolant in the second chamber 26, and ensuring the normal operation of the first heat dissipation component 2. By opening air flow holes 33 on the second heat dissipation fin 32, the air flow holes 33 inside the second heat dissipation fin 32 are conducive to air flow. When the cooling fan 34 is working, it accelerates the air flow speed between the second heat dissipation fins 32, which can quickly remove the heat on the second heat dissipation fins 32 and discharge it to the outside of the base 31 through the exhaust port.
