Embodiment Construction
[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0030] The method of realizing the conversion of time and depth through the weight change of the downhole tool and tool firstly sets up the surface tool, and then performs the downhole operation of the tool, such as figure 1 Shown is a schematic diagram of the logging device structure. A traveling block 5 is suspended under the roller on the crown block 1 at the wellhead, and a hook 6 is installed under the traveling block 5. The winch 3 on the ground is connected to the crown block 1 through a wire rope 2. The upper roller, the other side of the roller of the crane 1 is connected with a dead rope 4, the lower end of the dead rope 4 is connected to the ground roller 8, and a fixed bracket for installing the hook load tension sensor 9 is installed on the lower part of the dead rope 4 7. The lower end...
