Description

Technical Field

[0001] The utility model relates to the field of downhole salvage, in particular to a salvage device for a quick-connect wireless while-drilling inclinometer. Background Art

[0002] A wireless inclinometer is an instrument used in directional drilling. It can measure and monitor the direction and angle of the borehole in real time during the drilling process, ensuring that the drilling is carried out according to the preset trajectory, thereby improving the accuracy and efficiency of drilling. The wireless inclinometer solves the problem of inability to measure inclination in the upper fast drilling section and deep wells and high-temperature wells, while reducing the cost of construction and maintenance. However, accidents of drill bit falling off may occur during the drilling construction process, and a special salvage device is usually used.

[0003] Currently, when a salvage device for a wireless while-drilling inclinometer is used, the installation structure of the salvage device is relatively complicated and cumbersome, and it takes a certain amount of time to connect with other components, which is not conducive to improving the convenience of using the salvage device for the wireless while-drilling inclinometer.

[0004] Therefore, the installation structure of the above-mentioned salvage device is relatively complicated and cumbersome, and it takes a certain amount of time to connect with other components, which is not conducive to improving the convenience of using the salvage device. A quick-connect salvage device for a wireless downhole inclinometer can be designed. Utility Model Content

[0013] Beneficial effects of the utility model:

[0014] 1. This quick-connect wireless inclinometer fishing device is designed to install and lock the fishing device by inserting the mounting section and the connecting plug into the mounting sleeve. The mounting sleeve is rotated with an auxiliary tool to thread the mounting sleeve and the mounting section until they are tightly connected and the threaded through groove and the annular locking groove are aligned. The tool is used to rotate the hexagonal connecting block, so that one end of the locking piece moves to the inside of the annular locking groove and squeezes the mounting section, thereby completing the installation and locking of the fishing device. This improves the convenience of using the device and the connection stability.
