Description

Technical Field

[0001] The invention relates to the technical field of mining, and in particular to a bridle for well logging based on sandstone-type uranium mines. Background Art

[0002] As an important type of uranium resource, logging operations in the exploration and mining process of sandstone uranium mines play a key role in accurately obtaining formation information and evaluating uranium reserves and quality. In the logging process, it is usually necessary to use cables to connect downhole logging instruments to ground equipment to achieve functions such as data transmission and power supply.

[0003] As a key component for connecting logging instruments and cables, the bridle is connected to the logging instrument at one end and connected to the cable through a cable connector at the other end. At present, conventional cable connectors are widely used in the field of sandstone uranium mine logging. The main design purpose is to achieve reliable electrical connection and a certain degree of mechanical connection stability to ensure the normal transmission of signals and electrical energy during logging operations.

[0004] During the logging process of sandstone uranium mines, some emergencies may occur, such as the downhole instrument getting stuck, the well wall collapsing, and other abnormal situations. When these emergencies occur and the cable needs to be forcibly pulled to pull the downhole equipment to the ground, since the existing cable connector is tightly connected to the bridle and lacks an automatic disconnection function, the strong pulling force is often transmitted to the entire logging instrument string through the cable, which can easily cause the instrument string to twist, deform, or even break underground, thereby causing damage to the downhole instrument, which not only brings huge economic losses, but may also affect subsequent logging operations and the entire uranium mine exploration process.

[0005] Moreover, this forced pulling may cause the cable itself to break in extreme cases. Once the cable breaks and falls into the well, the subsequent salvage and repair work will be extremely complicated and difficult, further increasing the operating cost and time cost.

[0006] After the normal logging operation is completed, the downhole equipment needs to be recovered to the surface. However, the existing connection method of the cable connector and the bridle makes the separation operation relatively cumbersome, and usually requires manual use of specific tools to perform more complex disassembly operations at the wellhead, which to a certain extent reduces the overall efficiency of the logging operation. Especially in sandstone uranium exploration projects where frequent logging equipment downhole and recovery operations are required, the disadvantage of this inflexibility of operation is more obvious.

[0007] In view of the above-mentioned problems existing in the existing cable joints in the application of sandstone uranium mine logging, a new type of bridle is urgently needed to solve these problems. Summary of the invention

[0008] In order to solve the above problems, the present invention designs a bridle for well logging based on sandstone type uranium mines.

[0009] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions: A bridle for logging in sandstone-type uranium mines, comprising a lower outer cover, a fixing plate is tightened in the middle of the top wall of the lower outer cover, a joint is provided on the top wall of the fixing plate, a groove is provided on the upper end surface of the joint, a connecting head is provided on the bottom end wall of the fixing plate, and the bottom end of the connecting head extends into the lower outer cover; A middle outer cover is provided on the top wall of the lower outer cover, and a plurality of clamping mechanisms are plugged into the outer wall of the middle outer cover; An upper outer cover is provided on the top wall of the middle outer cover, an unlocking mechanism is provided on the outer wall of the upper outer cover, a circular groove is provided on the upper end surface of the upper outer cover, and a column is inserted through the upper outer cover; The bottom end of the column extends into the middle outer cover and is provided with a plug, the bottom end wall of the plug is provided with a contact, the outer wall of the plug is provided with a plurality of jacks, the outer wall of the column is connected with a top plate by interference fit, the lower end wall of the top plate is provided with a sealing gasket, and the top end wall of the column is provided with a fixing seat.

[0010] Furthermore, the locking mechanism includes a cylinder, a baffle is fixedly inserted in the cylinder, a spring is provided on the inner end wall of the baffle, a spring seat is provided on the inner end wall of the spring, the inner end of the spring seat extends out of the cylinder and is provided with an insert block, a sliding rod is provided on the outer wall of the spring seat, and the outer end of the sliding rod passes through the baffle.

[0011] Furthermore, the inner end wall of the insert block is of beveled design.

[0012] Furthermore, the unlocking mechanism includes a cylindrical shell, a cylinder, a base, a lever and a battery pack, wherein the plurality of cylindrical shells are arranged on the outer wall of the upper outer cover, a cylinder is arranged on the inner wall of the cylindrical shell, a driving bottom end of the cylinder extends into the middle outer cover and is provided with a base, a plurality of levers are arranged on the bottom end wall of the base, and the battery pack is arranged on the inner wall of the upper outer cover.

[0013] Furthermore, the contact surfaces of the shifting rod and the inserting block are arranged in parallel, are equal in number, and are arranged in relative positions up and down.

[0014] Furthermore, the jacks are arranged on the outer wall of the plug with circumferential gaps.

[0015] Furthermore, the fixing seat, the column and the plug are hollow structures, and the inner cavities are connected.

[0016] The beneficial effects of the present invention are: The cable connector of the present invention adopts a design that facilitates quick separation. This design enables quick and easy separation from the bridle without complicated manual disassembly operations during the recovery stage, greatly improving the overall efficiency of the logging operation. It is particularly suitable for situations where frequent logging equipment downhole and recovery operations are required in sandstone-type uranium mine exploration projects, effectively saving the time spent on each recovery operation and improving the fluency of the entire logging operation process. The exploration process of sandstone-type uranium mines involves frequent logging equipment operations, including downhole and recovery. This cable connector based on the sandstone-type uranium mine logging bridle that can automatically disconnect takes into account the special circumstances and actual needs of the exploration process of this type of mine. It can not only effectively protect downhole equipment and cables in emergency situations, but also improve efficiency in conventional recovery operations, so as to better adapt to the requirements of frequent and efficient operation of logging equipment in the exploration process of sandstone-type uranium mines, and provide powerful and reliable technical support for the efficient exploration and mining of sandstone-type uranium mines, which is helpful to promote the development of the entire sandstone-type uranium mine industry. The patented cable connector can protect the cable at critical moments through an automatic disconnection mechanism, preventing the cable from breaking and falling into the well due to excessive pulling. The cable connector can effectively avoid this situation, reduce the trouble of subsequent complex operations such as cable salvage and repair, further save operating costs and time costs, and improve the economy and timeliness of the entire logging operation.
