[0023] The embodiment of the present application provides a logging device for horizontal directional drilling engineering, which is used in conjunction with a horizontal directional drilling rig, and the logging device is located in the horizontal directional drilling rig, and the logging device includes: a sealing assembly, a probe, a telescopic member and a protective member.

And the protective member is sleeved in the sealing assembly. Among them, in the horizontal directional drilling engineering, the probe receives the contact force, the telescopic member drives the probe, and the probe is located in the protective member.

[0024] The probe in the equipment is located at the front end of the working direction, which can directly contact the formation and receive accurate contact force information. The probe is connected by a telescopic piece and fits with the protective piece in the sealing assembly. This design not only protects the structural integrity of the probe, but also allows the probe to be fine-tuned through the telescopic piece when necessary to adapt to different formation conditions.

[0025] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] See also Figure 1-Figure 3 The embodiment of the present application provides a logging device 100 for horizontal directional drilling engineering, which is used in conjunction with a horizontal directional drilling rig, and the logging device 100 is located in the horizontal directional drilling rig, and the logging device 100 includes: a sealing assembly 10, a probe 20, a telescopic member 30 and a protective member 40. The sealing assembly 10 is used to protect the internal structure of the logging device 100. The probe 20 is located in the sealing assembly 10, and the probe 20 is located at the front end of the working direction F1 of the horizontal directional drilling rig. One end of the telescopic member 30 is connected to the probe 20, and the other end of the telescopic member 30 is connected to the sealing assembly 10. The telescopic member 30 is located in the sealing assembly 10. One end of the protective member 40 is connected to the sealing assembly 10, and the other end of the protective member 40 is in contact with the probe 20. And the protective member 40 is sleeved in the sealing assembly 10. Among them, in the horizontal directional drilling engineering, the probe 20 receives the contact force, the telescopic member 30 drives the probe 20, and the probe 20 is located in the protective member 40.

[0027] Specifically, the sealing assembly 10 is the first line of defense of the logging device 100, and its main function is to prevent mud, water or other impurities from entering the interior of the device, thereby protecting the internal structure and electronic components of the device from damage. The sealing assembly 10 includes a front housing 111 and a rear housing 112, which are arranged opposite to each other. The front housing 111 is located in the front of the forward direction during the drilling process to resist direct impact from the formation.

[0028] Furthermore, effective sealing protection can ensure that the equipment operates stably and reliably in a complex underground environment and improve the service life of the equipment. The provision of the front housing 111 can further enhance the impact resistance of the equipment and protect the equipment from direct damage by the formation conditions.

[0029] Furthermore, the probe 20 is a core component of the logging device 100. It is located in the sealing assembly 10 and directly contacts the formation to receive and measure formation information. The probe 20 can measure various parameters of the formation, such as microresistivity, hardness, thickness, rock type, etc., to provide key geological data support for horizontal directional drilling projects. The real-time and accurate measurement of the probe 20 can ensure that the engineering team has a clear understanding of the formation conditions, so as to formulate a more scientific drilling plan. The multi-parameter measurement capability of the probe 20 can improve the comprehensiveness and accuracy of the data, and provide a more reliable basis for engineering decision-making.

[0030] Furthermore, the telescopic member 30 connects the probe 20 and the sealing assembly 10, and the position and measuring angle of the probe 20 can be adjusted through telescopic movement. The design of the telescopic member 30 enables the probe 20 to flexibly adapt to different formation conditions, such as rock hardness, crack distribution, etc.

[0031] The flexibility of the telescopic member 30 can ensure that the probe 20 always maintains the best contact state with the formation, thereby improving the accuracy of the measurement. The adjustment capability of the telescopic member 30 can adapt to the changes in different formation conditions, thereby improving the adaptability and reliability of the equipment.

[0032] The protective member 40 is sleeved in the sealing assembly 10, one end of which is connected to the sealing assembly 10, and the other end is fitted to the probe 20, for protecting the probe 20 from physical impact and chemical corrosion. The protective member 40 can effectively reduce the direct impact and wear of the formation on the probe 20, while preventing the erosion of chemical substances.

[0033] The protective function of the protective member 40 can extend the service life of the probe 20 and reduce the equipment maintenance cost. The existence of the protective member 40 can ensure that the probe 20 can still work stably in a harsh environment and improve the reliability and durability of the equipment.

[0034] In summary, the probe 20 is located inside the protective member 40, and this design further enhances the protection effect of the probe 20. The protective member 40 can block direct impact from the formation and chemical corrosion, ensuring that the probe 20 is not damaged. With the protection of the protective member 40, the probe 20 can work stably in a more severe environment, improving the accuracy of measurement and the reliability of the equipment. The design of the probe 20 being located inside the protective member 40 also facilitates the maintenance and replacement of the equipment.

[0035] In a specific implementation example, the sealing assembly 10 further includes a sealing housing 11 , and the sealing housing 11 includes a front housing 111 and a rear housing 112 disposed opposite to the front housing 111 , and the front housing 111 is located at the front during the drilling process.

[0036] Specifically, the front housing 111, as one of the main parts of the sealing housing 11, is located at the front end of the drilling direction, directly facing the impact of the formation and mud, water and other impurities that may be generated during the drilling process. Its main function is to serve as a protective barrier to resist the erosion of the external environment and ensure the integrity of the internal structure and components.

[0037] Furthermore, the rear housing 112 is arranged opposite to the front housing 111, and together with the front housing 111, forms a complete sealed housing 11. The rear housing 112 is mainly used to connect and support other internal components, such as the probe 20, the telescopic member 30, etc., while maintaining the overall structure and stability of the sealed housing 11.

[0038] Furthermore, the combined design of the front housing 111 and the rear housing 112 greatly enhances the protection capability of the sealing assembly 10, effectively prevents the external environment from damaging the internal structure, and improves the stability and reliability of the logging device 100. The relative arrangement of the front housing 111 and the rear housing 112 makes the layout of the internal components more reasonable, which is conducive to reducing the volume of the equipment and improving the space utilization rate, and is also conducive to the maintenance and replacement of the internal components. By enhancing the protection capability and optimizing the structural layout, the service life of the logging device 100 can be extended, the maintenance cost can be reduced, and the economic benefits can be improved.

[0039] In summary, in the horizontal directional drilling project, the logging equipment 100 moves forward with the horizontal directional drilling rig. At this time, the front shell 111, as the front end of the sealing shell 11, first contacts the external environment such as the formation and mud. The front shell 111 effectively blocks the erosion of the internal components by the external environment through its solid structure and sealing performance. At the same time, the rear shell 112 ensures the stability and reliability of the entire sealing assembly 10 by connecting and supporting other internal components. During the drilling process, the front shell 111 and the rear shell 112 work together to provide a safe and stable working environment for the internal components.

[0040] In a specific implementation example, the sealing assembly 10 includes a protective shell 12 , one end of the protective shell 12 is fixedly connected to the telescopic member 30 , and the other end of the protective shell 12 is slidably connected to the rear shell 112 .

[0041] Specifically, the protective housing 12 is an important component of the sealing assembly 10, and its design is intended to further enhance the stability and safety of the logging device 100 during drilling. The protective housing 12 cooperates with the telescopic member 30 and the rear housing 112 to form a flexible protection system.

[0042] Furthermore, one end of the protective shell 12 is fixedly connected to the telescopic member 30, ensuring that when the telescopic member 30 performs telescopic movement, the protective shell 12 can move synchronously, providing stable support and protection for the probe 20. The design of the protective shell 12 increases the stability of the logging equipment 100 during the drilling process, and effectively prevents equipment damage caused by changes in formation conditions or vibrations. The sliding connection design between the protective shell 12 and the rear shell 112 enables the equipment to adapt to different working environments and formation conditions, improving the adaptability and reliability of the equipment. The design of the protective shell 12 makes the maintenance and overhaul of the equipment more convenient and quick, reducing maintenance costs and time.

[0043] Furthermore, in the horizontal directional drilling project, when the formation conditions change or vibration occurs, the telescopic member 30 will perform telescopic movement as needed to adjust the position and measurement angle of the probe 20. At this time, the protective housing 12 fixedly connected to the telescopic member 30 will also move synchronously to provide stable support and protection for the probe 20. At the same time, the sliding connection design between the other end of the protective housing 12 and the rear housing 112 allows the protective housing 12 to slide in a certain direction when necessary to adapt to different working environments and formation conditions. This flexible sliding connection design enables the device to better cope with various complex situations and improves the stability and reliability of the device.

[0044] Furthermore, when drilling in complex formations (such as mudstone layers, soft soil layers, etc.), the formation conditions vary greatly, which can easily cause damage to the logging equipment 100. At this time, the design of the protective shell 12 can effectively protect the equipment from damage by the formation conditions and improve the stability and reliability of the equipment. At the same time, during the drilling process, the equipment may be subjected to large vibrations and shocks. The design of the protective shell 12 can reduce the impact of vibration on the equipment and ensure that the equipment can still work stably in a high-vibration environment. In addition, in some drilling projects, it is necessary to frequently adjust the position and measurement angle of the probe 20. At this time, the design of the telescopic member 30 and the protective shell 12 makes the adjustment process more convenient and quick, and improves work efficiency and accuracy.

[0045] In a specific implementation example, the protection housing 12 is sleeved in the sealing housing 11 , and the protection housing 12 slides along a sliding direction away from the working direction F1 .

[0046] Specifically, the protective shell 12 can be tightly inserted into the sealing shell 11. Such a structure can ensure the stability and sealing between the protective shell 12 and the sealing shell 11, and prevent mud, water or other impurities in the external environment from entering the sealing assembly 10 and affecting the normal operation of the equipment.

[0047] Furthermore, during the drilling process, due to changes in formation conditions or work requirements, the protection housing 12 can slide in a sliding direction away from the working direction F1. This design allows the protection housing 12 to provide a certain buffering effect when necessary, reducing the direct impact of the formation on the probe 20, thereby protecting the probe 20 from damage.

[0048] Furthermore, the protective housing 12 is sleeved in the sealing housing 11, which enhances the sealing performance of the entire sealing assembly 10 and effectively prevents impurities in the external environment from entering the interior of the device. The protective housing 12 can slide in a sliding direction away from the working direction F1, providing additional protection for the probe 20, reducing the direct impact of the formation on the probe 20, and improving the service life and reliability of the equipment. The sliding design enables the protective housing 12 to be adjusted according to different formation conditions and working requirements, enhancing the adaptability and flexibility of the equipment.

[0049] Furthermore, in the horizontal directional drilling project, when the formation conditions change or the position of the probe 20 needs to be adjusted, the telescopic member 30 will drive the probe 20 to move accordingly. At the same time, since the protective shell 12 is fixedly connected to the telescopic member 30, the protective shell 12 will also move accordingly. When it is necessary to provide additional protection or buffering for the probe 20, the protective shell 12 can slide in a sliding direction away from the working direction F1, thereby forming a certain buffer space between the formation and the formation, reducing the direct impact of the formation on the probe 20.

[0050] In a specific implementation example, the protective housing 12 includes: a protective member 121, a sliding member 122 and a sliding channel 123. The protective member 121 is sleeved in the sealed housing 11. One end of the sliding member 122 is slidably connected to the protective member 121, and the other end of the sliding member 122 is connected to an end of the telescopic member 30 away from the probe 20. The sliding channel 123 is opened with the sliding member 122, and the sliding channel 123 is attached to and slidably connected with the sliding member 122.

[0051] Specifically, the protective member 121 is the main part of the protective housing 12, which is sleeved in the sealing housing 11 to provide additional protection for the probe 20. When the probe 20 is impacted, it can reduce the damage caused by the impact to the probe 20 through its own structure and material properties, thereby enhancing the durability and reliability of the logging device 100 and extending the service life of the device.

[0052] Furthermore, the sliding member 122 is a key part connecting the protective member 121 and the telescopic member 30. One end of the sliding member 122 is slidably connected to the protective member 121, and the other end is connected to the telescopic member 30. When the telescopic member 30 moves, the sliding member 122 can drive the protective member 121 to slide in the sealed housing 11 to adapt to different working conditions. The sliding function of the protective housing 12 is realized, and the adaptability and flexibility of the device are improved.

[0053] Furthermore, the sliding channel 123 is provided on the sliding member 122, and is attached to and slidably connected with the sliding member 122. The sliding channel 123 provides a stable sliding path for the sliding member 122, ensuring the smooth sliding of the sliding member 122 in the protective housing 12. The smoothness and accuracy of the sliding of the sliding member 122 are ensured, and the stability and reliability of the device are improved.

[0054] Furthermore, in a horizontal directional drilling project, when a complex stratum is encountered or the position of the probe 20 needs to be adjusted, the telescopic member 30 will drive the probe 20 to move accordingly. Since one end of the sliding member 122 is connected to the telescopic member 30 and the other end is slidably connected to the protective member 121, the movement of the telescopic member 30 will drive the sliding member 122 and the protective member 121 to slide together. The sliding member 122 slides in the sliding channel 123 to ensure the stability and accuracy of the sliding. The sliding of the protective member 121 can adjust its relative position with the probe 20 to adapt to different working conditions.

[0055] In a specific implementation example, the logging device 100 further includes a sealing gasket 50 , which is sleeved on an end of the protective member 40 away from the probe 20 , and the sealing gasket 50 is located between the protective member 40 and the front shell 111 .

[0056] Specifically, the main function of the sealing gasket 50 is to form a sealing interface between the protective member 40 and the front shell 111 to prevent mud, water or other liquid impurities from entering the interior of the sealing assembly 10, thereby protecting the internal structure of the logging equipment 100 and key components such as the probe 20.

[0057] Furthermore, the sealing gasket 50 can also provide a certain buffering effect. When the protective member 40 is impacted or vibrated during drilling, the sealing gasket 50 can absorb part of the impact force, reduce the direct collision between the protective member 40 and the front shell 111, and thus extend the service life of the equipment.

[0058] Furthermore, by adding the sealing gasket 50, the sealing performance of the logging device 100 in complex environments can be greatly improved, ensuring that the device can work stably and reliably during drilling. The cushioning effect of the sealing gasket 50 can reduce the direct collision between the protective member 40 and the front housing 111, reduce the risk of damage to the device due to impact, and thus improve the durability and service life of the device. The design of the sealing gasket 50 enables the logging device 100 to better adapt to various complex environments and formation conditions, and improves the adaptability and reliability of the device.

[0059] Furthermore, during the drilling process, when the protective member 40 is impacted by the formation or other external factors, the sealing gasket 50 will first bear this part of the impact force. Since the sealing gasket 50 has a certain elasticity and compressibility, it can absorb part of the impact force and transfer the remaining impact force to the front housing 111. In this way, the direct collision between the protective member 40 and the front housing 111 is greatly reduced. At the same time, the sealing gasket 50 can also prevent mud, water or other liquid impurities from entering the interior of the sealing assembly 10, ensuring that the internal structure of the equipment and key components such as the probe 20 are not damaged.

[0060] In a specific implementation example, the logging device 100 further includes a connector 60 , and the connector 60 is respectively connected to the front housing 111 and the rear housing 112 . The front housing 111 and the rear housing 112 are connected via the connector 60 .

[0061] Specifically, the main function of the connector 60 is to ensure a stable connection between the front housing 111 and the rear housing 112. In horizontal directional drilling engineering, this stable connection is crucial to ensure the integrity and functionality of the internal structure of the logging device 100. The design of the connector 60 ensures that it can be firmly connected to the front housing 111 and the rear housing 112 at the same time. This design can prevent relative displacement or loosening between the front housing 111 and the rear housing 112 due to complex formation conditions or external force impact during the drilling process.

[0062] Furthermore, the connector 60 ensures a stable connection between the front housing 111 and the rear housing 112, thereby ensuring the stability and reliability of the logging device 100 during drilling. Through the connector 60, the connection between the front housing 111 and the rear housing 112 is stabilized, effectively preventing loosening due to vibration or impact, and extending the service life of the equipment. The stable connection ensures the integrity of the internal structure of the logging device 100, thereby improving the overall performance of the device, such as measurement accuracy, response speed, etc.

[0063] Furthermore, in a horizontal directional drilling project, when the horizontal directional drilling machine starts working, the logging device 100 also starts working. At this time, the connecting member 60 plays a vital role. It ensures that the front housing 111 and the rear housing 112 are always stably connected, regardless of the formation conditions or external force impacts. When the telescopic member 30 drives the probe 20 to move, due to the stable connection of the connecting member 60, the front housing 111 and the rear housing 112 can work together to maintain the overall stability and reliability of the logging device 100.

[0064] In a specific implementation example, the connecting member 60 is sleeved on the outside of the sealed shell 11 , and the connecting member 60 is located between the front shell 111 and the rear shell 112 .

[0065] Specifically, by sleeve-arranging the connector 60 outside the sealing housing 11, it can be easily installed and disassembled, which is convenient for the maintenance and care of the equipment. The connector 60 is located between the front housing 111 and the rear housing 112, and can effectively connect the two together to form a complete sealing assembly 10, ensuring the stability and sealing of the internal structure. The external sleeve connector 60 can select suitable materials and structures according to the specific application environment and requirements to improve the adaptability and durability of the equipment.

[0066] Furthermore, during the device assembly process, the front housing 111 and the rear housing 112 are first installed according to the design requirements, and then the connector 60 is sleeved outside the sealing housing 11 to ensure that the connection between the connector 60 and the front housing 111 and the rear housing 112 is tight and reliable. When the device is working, the connector 60 will play a role of fixing and supporting, ensuring that the relative position between the front housing 111 and the rear housing 112 remains unchanged, thereby maintaining the overall stability of the sealing assembly 10.

[0067] In a specific implementation example, the connecting member 60 includes a threaded portion 61, the threaded portion 61 is located at an end away from the rear housing, and the threaded portion 61 is connected to the horizontal directional drilling machine.

[0068] Specifically, the connector 60 ensures the stability and overall performance of the internal structure of the device. The threaded portion 61 is a specific component of the connector 60, and is connected to the horizontal directional drilling machine through a thread. The threaded portion 61 is located at the end away from the sealed housing 11, which means that the threaded portion 61 is arranged at the end of the connector 60 away from the sealed housing 11, which is convenient for connection with external equipment.

[0069] Furthermore, the threaded portion 61 is disposed at the other end of the connector 60, i.e., the end away from the probe 20, which helps maintain the stability and position accuracy of the probe 20. By connecting the threaded portion 61 to the horizontal directional drilling rig, a stable connection between the logging device 100 and the drilling rig can be ensured, reducing the possibility of loosening or falling off during the drilling process.

[0070] Furthermore, threaded connection is a common connection method, which is easy to install and disassemble, and is convenient for equipment maintenance and replacement. Threaded connection can adapt to different connection requirements by adjusting the tightening degree of the thread, and has good adaptability.

[0071] Furthermore, when the logging device 100 is connected to the horizontal directional drilling machine, the threaded portion 61 of the connecting member 60 is first aligned with the corresponding interface on the drilling machine, and then the connecting member 60 is rotated to screw the threaded portion 61 into the interface until it is tightened. In this way, the logging device 100 is stably connected to the horizontal directional drilling machine through the threaded portion 61 of the connecting member 60.

[0072] In a specific implementation example, the front housing 111 and the rear housing 112 are both made of titanium alloy.

[0073] Specifically, the front housing 111 and the rear housing 112 are two main components of the sealing assembly 10, which together constitute the outer shell of the sealing assembly 10, and are used to protect the internal structure of the logging device 100. Titanium alloy is a lightweight, high-strength metal material with good corrosion resistance, high temperature resistance and fatigue resistance. In the present application, the front housing 111 and the rear housing 112 are both made of titanium alloy.

[0074] Furthermore, titanium alloy has low density but high strength, which allows the front housing 111 and the rear housing 112 to maintain sufficient strength while greatly reducing the overall weight of the logging device 100. This has important practical significance for the carrying and operation of equipment in horizontal directional drilling projects.

[0075] Furthermore, titanium alloy has excellent corrosion resistance and can maintain stability for a long time even in a humid and highly corrosive environment. This can ensure long-term stable operation of the logging device 100 working in a complex underground environment.

[0076] Furthermore, titanium alloy can still maintain good mechanical properties in high temperature environment, which enables the logging device 100 to work normally when encountering high temperature formation during drilling. At the same time, titanium alloy has good fatigue resistance and can withstand repeated stress without breaking or failure. This can greatly improve the service life and reliability of the logging device 100 that needs to drill and measure frequently.

[0077] In summary, in the horizontal directional drilling project, the logging device 100 is installed inside the horizontal directional drilling rig and moves with the drilling of the rig. In this process, the front housing 111 and the rear housing 112, as the outer shell of the sealing assembly 10, are subjected to various pressures and impacts from the formation and the drilling process. Due to the titanium alloy structure, the front housing 111 and the rear housing 112 can effectively resist these pressures and impacts, ensuring the stability and safety of the internal structure of the logging device 100.

[0078] Thus, the logging device 100 for horizontal directional drilling engineering provided above can be fine-tuned by the probe 20 through the telescopic member 30 when necessary to adapt to different formation conditions. Through the flexibility of the telescopic member 30 and the protection of the protective member 40, the probe 20 can more accurately sense the formation conditions, thereby improving the accuracy and reliability of the entire logging device 100.

[0079] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
