Problems solved by technology
[0002] At present, it is generally used in the connection between the weighted rod and the logging cable of the horizontal well docking tool. Generally, it cannot be made into a weak point. Usually, a special outer taper sleeve, a middle taper sleeve, and an inner taper sleeve are used to fix the cable and install it on the torpedo. It is connected with the weighted rod, and the tensile strength after connection is the same as that of the logging cable. There is no way to make an ideal pull-off force, and the installation operation can only be completed with the help of special tools, which is very inconvenient.

Embodiment Construction
[0010] exist figure 1 Among them, the torpedo head 1 and the torpedo body 9 are connected by threads, the center of the torpedo head 1 is drilled with a torpedo head inner hole 11, the sleeve 2 is set on the torpedo body 9, and the center of the torpedo body 9 is drilled with a main body inner hole 12, and is provided with Slotted inner hole 16, in the slotted inner hole 16, put the outer cover 3, the inner cover 5, the gasket 6, the slotted stopper 8, the outer cover is fixed with two top screws 4, and the slotted stopper 8 is fixed with two top screws. The wire 7 is fixed, and finally connected with the weighted rod of the horizontal well docking tool by the connecting rod 10, which is generally cylindrical.

Description
technical field [0001] The invention relates to the field of oil field logging instruments, in particular to a connection device between a logging cable and a horizontal well logging tool, and a new type of torpedo for connecting a logging cable to a horizontal well docking tool. Background technique [0002] At present, it is generally used in the connection between the weighted rod and the logging cable of the horizontal well docking tool. Generally, it cannot be made into a weak point. Usually, a special outer taper sleeve, a middle taper sleeve, and an inner taper sleeve are used to fix the cable and install it on the torpedo. It is connected with the weighted rod again, and the tensile strength after connection is the same as that of the logging cable. There is no way to make a relatively ideal pull-off force, and the installation operation can only be completed with the help of special tools, which is very inconvenient. Contents of the invention [0003] In order to ...
