Description

(1) Technical field [0001] The invention relates to an oil field logging tool, in particular to a cable locker for connecting male and female joints of a horizontal well. (2) Background technology [0002] There are two types of production wells in oilfields, one is straight-through wells whose well deviation does not exceed 20m, and the second is well deviation greater than 80°, even more than 90°, commonly known as horizontal wells. Horizontal well logging is very difficult. In the case of bare rod wells, it is necessary to use drilling tools to push the logging tool to 4000-5000m in the direction of well deviation for logging. This task needs to be completed with horizontal well tools. [0003] Horizontal well tool is a special logging tool, which is very important to the test of horizontal well. One end of it is connected to the 7-core cable wet male connector logging tool, and the other end of the 7-core cable wet female connector is connected to the mud pump system. W...
