Description

Technical Field

[0001] This utility model relates to the field of downhole detection technology, specifically, to a downhole detector. Background Technology

[0002] In the field of downhole exploration technology, downhole detectors are a key piece of equipment, widely used in geological exploration, mine monitoring, oil and gas extraction, underground engineering, and water resource surveys. Their main function is to acquire downhole geological structures, wellbore conditions, cavity information, and other relevant data through optical, electronic, or other sensor technologies, providing scientific basis and technical support for the development and utilization of underground resources. In geological exploration, downhole detectors can help geologists understand the distribution of underground rock strata, the properties of rocks, and possible geological structures such as faults and folds, thus providing important information for the exploration and assessment of mineral resources.

[0003] Existing downhole detectors typically employ a single-camera structure, with the camera only capable of downward axial detection, primarily used to acquire image data from the bottom of the well. However, this single-camera detection method has significant limitations. First, when observing the well wall and cavities, the single-camera detector has a narrow field of view, acquiring only limited axial image data. It is difficult to comprehensively capture crucial information such as the shape and size of cracks, holes, and cavities in the well wall. This limitation of perspective leads to the emergence of imaging blind spots, easily overlooking important geological features and thus affecting the accurate assessment of the downhole environment. Second, in complex downhole environments, especially under low-light conditions, single-camera detectors often struggle to obtain high-quality image data, further limiting their application scope and detection effectiveness. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a downhole detector, which solves the technical problem that existing downhole detectors in the prior art usually adopt a single camera structure, making it difficult to fully capture key information such as the shape and size of cracks, holes and cavities in the well wall.

[0005] The device includes a rotating base, with a fixed base 1 fixedly connected inside the rotating base. A light guide plate 1 is disposed inside the rotating base. A fill light 1 is fixedly connected to one side of the surface of the fixed base 1, and a camera 1 is fixedly connected to the other side of the surface of the fixed base 1. A clamping plate is fixedly installed on the surface of the rotating base. A fill light 2 and a fill light 3 are disposed inside the rotating base. A light guide plate 2 is disposed on the surface of the fill light 2, and a light guide plate 3 is disposed on the surface of the fill light 3. A camera 2 is disposed inside the rotating base, and a light guide plate 4 is disposed on the surface of the camera 2.

[0006] The above technical solution provides sufficient auxiliary light source for the camera by setting three supplementary lights, which can significantly improve the imaging effect, especially in low light environment, and ensure clear imaging of the downhole environment. The use of two cameras to shoot from different directions increases the lateral image data, which can more comprehensively and accurately analyze the structural characteristics of the well wall and cavity, making up for the shortcomings of the traditional single-camera structure. The stability of each component in the complex downhole environment is ensured by fixing devices such as the clamping plate 7 and the lock nut 1, which improves the reliability and service life of the detector.

[0007] As a further improvement to the above solution, the light-transmitting end face of the first camera is connected to the first light guide plate, and the light-transmitting end face of the second camera is connected to the fourth light guide plate.

[0008] The above technical solution guides the light from the supplementary light to the light-transmitting end face of the camera evenly through the light guide sheet, avoiding image blurring or shadow problems caused by uneven light distribution, improving image clarity and consistency, and ensuring that the camera can obtain high-quality images even in low-light environments.

[0009] As a further improvement to the above solution, cavities are provided on both sides of the rotating base body, and the second and third supplementary lights are fixedly installed inside the two cavities respectively.

[0010] The above technical solution, through an independent cavity design, ensures that the light from the supplementary lamp can be distributed more evenly, further improving the image quality.

[0011] As a further improvement to the above solution, the second supplementary light is connected to the second light guide plate, and the third supplementary light is connected to the third light guide plate.

[0012] The above technical solution guides the light from the supplementary light to the light-transmitting end face of the camera evenly through the light guide sheet, which improves the light utilization efficiency, ensures the clarity and consistency of the image, and provides sufficient auxiliary light source for the camera. Especially in low light environment, it can significantly improve the image quality and ensure clear imaging of the underground environment.

[0013] As a further improvement to the above solution, a second fixed base is fixedly connected inside the rotating base, and the second camera is fixedly installed on the surface of the second fixed base.

[0014] As a further improvement to the above solution, the fill light and the camera are connected to the surface of the fixed base via a lock nut, and a clamping plate is engaged with the surface of the rotating base.

[0015] As a further improvement to the above solution, the light guide sheet 1, light guide sheet 2, light guide sheet 3 and light guide sheet 4 are all made of transparent material and are used to uniformly guide the light from the supplementary light to the light-transmitting end face of the camera.

[0016] Through the above technical solutions, the transparent light guide sheet can efficiently transmit light and ensure the uniform distribution of light.

[0017] As a further improvement to the above solution, the fill light one, fill light two and fill light three are all used to provide auxiliary light sources for the camera to enhance the imaging effect in low light environment.

[0018] The beneficial effects of this utility model are as follows: This invention significantly improves the comprehensiveness and accuracy of downhole detection by employing a dual-camera structure with mutually perpendicular axial and radial directions. On one hand, camera one and camera two image the well wall and cavity from different directions, increasing lateral image data and enabling a more comprehensive capture of structural features such as cracks, holes, and the shape and size of cavities in the well wall. This avoids the imaging blind spots and misjudgments caused by the single-camera structure due to its limited field of view. On the other hand, the combination of multiple supplementary lights and light guides ensures that the camera can still receive uniform and sufficient light in low-light environments, further improving image quality and enhancing adaptability to complex downhole environments. This not only compensates for the shortcomings of the single-camera structure but also expands the application range of the detector. Attached Figure Description
