Description

Technical Field

[0001] This utility model relates to the field of mud filtration technology, specifically a light hydrocarbon logging mud filtration device. Background Technology

[0002] Continuous light hydrocarbon logging technology uses a 120-second analysis cycle to continuously detect the content of 15 hydrocarbon components (C1-nC8) in the drilling fluid. By determining the content and variation of n-alkanes, isoalkanes, cycloalkanes, and aromatics in the hydrocarbon components, it enables real-time and effective analysis of reservoir gas content, oil content, and water content during drilling. This provides a valuable basis for understanding and evaluating reservoir fluid properties. During the implementation of this technology, an electric mud degasser is required to quantitatively extract mud from the drilling mud tank, thereby completing mud degassing, sample gas chromatography acquisition, and data analysis.

[0003] Currently, continuous light hydrocarbon logging technology uses mud suction heads to extract mud. Existing technologies disclose devices for mud filtration, but these devices require frequent cleaning by staff and are inconvenient to use. Therefore, a light hydrocarbon logging mud filtration device is proposed to address the above problems. Utility Model Content

Multiple nozzles 102, which communicate with the hollow rings 101, are fixedly connected to the outside of the hollow rings 101. The nozzles 102 are inclined, with the higher end of the nozzles 102 located inside the hollow rings 101. Through the filter cylinder 2, round hole 3, first sealing gasket 5, second sealing gasket 6, mesh cylinder 7, water pipe 8, baffle 9, water inlet assembly 10, and connecting pipe 11, when using the device, the frustum-shaped filter cylinder 2 can block larger stones and mud, while the mesh cylinder 7 can isolate smaller particles of mud. When cleaning the device, a high-pressure water pump can be started, and water is sprayed out through the nozzles 102, thereby backflushing the mud and sand adsorbed on the mesh cylinder 7. The mud and sand inside the outer shell 1 can be discharged through the round hole 3, and the stones in the filter cylinder 2 are also removed from the filter cylinder 2 with the high-speed flowing water. This design can reduce the cleaning frequency of the device and improve working efficiency.

[0027] Mounting assembly 4 includes a mounting plate 41 fixedly connected to the outside of housing 1. Mounting bolts 42 are provided on the inner side of the mounting plate 41, and mounting nuts 43 are threaded onto the outer side of the mounting bolts 42. The uppermost hollow ring 101 is fixedly connected to the bottom end of water pipe 8 and is in communication with water pipe 8. Multiple hollow rings 101 are fixedly connected to each other via connecting pipes 11 and are in communication with each other. Multiple connecting rods 12 are fixedly connected to the inner side of the lowermost hollow ring 101, and the end of each connecting rod 12 away from the hollow ring 101 is fixedly threaded. The inner side of the threaded cylinder 13 is threadedly connected to a threaded post 14 that is fixedly connected to the bottom of the inner side of the mesh cylinder 7. Through the installation components 4, installation hole plate 41, installation bolt 42, installation nut 43, connecting rod 12, threaded cylinder 13 and threaded post 14, after the device has been used for a long time, the installation nut 43 can be removed and the outer shell 1 can be opened. The mesh cylinder 7 can be rotated to disengage the threaded post 14 from the threaded cylinder 13, so that the various components inside the device can be cleaned. The design of the installation components 4 and its connecting components makes the installation and disassembly of the device more convenient.

[0028] Workflow: Before using the device, install each component. First, install the screen cylinder 7, placing it outside the inlet assembly 10. Tighten the threaded post 14 on the inside of the screen cylinder 7 to the threaded cylinder 13 at one end of the connecting rod 12. Then, place the screen cylinder 7 inside one of the outer shells 1, ensuring the baffle 9 is at the top of the outer shell 1. Place the mud suction head inside the screen cylinder 7, ensuring the mud suction head's pipe and water pipe 8 are inside the first sealing gasket 5 and the second sealing gasket 6, respectively. Next, use the installation assembly 4 to fix the outer shells 1, aligning the two outer shells 1. Insert the installation bolt 42 into the mounting hole plate 41, and tighten the installation nut 43 onto the outside of the installation bolt 42. This completes the installation of each component. Finally, connect the water pipe 8 to the high-pressure water pump, and the device can be used normally. When using the device, the mud suction head generates suction, drawing external mud through the round hole 3 on the filter cylinder 2 into the inner shell 1 and then into the screen cylinder 7. The frustum-shaped filter cylinder 2 design allows for… The screen cylinder 7 can block larger stones and silt from entering, while smaller particles of silt can be isolated. After the device has been used for a period of time, a lot of silt remains on both the inside and outside of the device. At this time, the high-pressure water pump can be started. The high-pressure water pump introduces water into the hollow ring 101 and the connecting pipe 11. The water is sprayed out through the spray pipe 102, thereby back-blowing the silt adsorbed on the screen cylinder 7. Due to the introduction of high-pressure water, the water pressure inside the outer shell 1 increases, and the silt inside the outer shell 1 can be discharged through the round hole 3 on the filter cylinder 2. The stones in the filter cylinder 2 also leave the filter cylinder 2 with the high-speed water flow. The design of the water inlet component 10 and its connecting components can back-blow the silt and stones in the device, reduce the cleaning frequency of the device, and improve work efficiency. After the device has been used for a long time, the mounting nut 43 can be removed and the outer shell 1 can be opened. The screen cylinder 7 can be rotated to disengage the threaded column 14 from the threaded cylinder 13 to clean the various components inside the device. The design of the mounting component 4 and its connecting components makes the installation and disassembly of the device more convenient.
