[0001] The utility model relates to the technical field of oilfield logging, in particular to an oilfield development logging device provided with a downhole hanging type protection structure. Background Art

[0002] An oil field refers to the sum of oil and gas reservoirs within the same oil and gas production area under the control of a single geological structural factor, including well site equipment, gathering and transportation pipelines, oil transfer pumping stations, and crude oil storage in the mine, etc. This requires sufficient land area and connection with oil pipelines, etc. In the process of oil field development, a logging device is often required to detect the oil field wellhead, but the existing oil field development logging device has some shortcomings, such as:

[0003] During the survey process, the existing oilfield development logging device will lower the detection device to the depth of the wellhead for detection. However, in the process of detection, due to the lack of protective equipment, the detection device may collide with the wellhead wall during the descent process, thereby causing damage to the detection device and reducing the efficiency of the equipment.

[0004] Therefore, we propose an oilfield development logging device with a downhole hanging protection structure, so as to solve the problem that the existing oil well detection device mentioned above may cause the detection equipment to collide with the wellhead wall during the descent process due to the lack of protective equipment, thereby causing damage to the detection equipment and reducing the efficiency of the equipment.

When the first protection wheel 18 is in contact with the oil well wall, if the oil well wall is too narrow, the first support arm 17 will rotate inward, so that the first spring shaft 13 is contracted, so that the first support arm 17 drives the protection layer 21 to move closer to the detector body 15, so that the first support arm 17, the second support arm 19 and the protection layer 21 protect the detector body 15, and prevent the debris on the upper part of the oil well from falling on the surface of the detector body 15;

When the first protection wheel 18 is in contact with the oil well wall, if the oil well wall is too narrow, the first support arm 17 will rotate inward, so that the first spring shaft 13 will shrink, so that the first support arm 17 drives the protection layer 21 to move closer to the detector body 15, so that the first support arm 17, the second support arm 19 and the protection layer 21 protect the detector body 15, and prevent the debris on the upper part of the oil well from falling on the surface of the detector body 15;

[0043] When the operating table 1 is fixed to the ground, the fixing nails 2 can be passed through the operating table 1 to connect to the ground, so that the operating table 1 can be fixed to the ground. When the connecting wire 7 is connected and fixed to the connecting plate 9, the interface at the bottom of the connecting wire 7 can be protected by the connector 10.
