Downhole tool to generate tension pulses on a slickline |
摘要 |
A downhole tool that is connectable to a line to be run downhole with the tool includes a housing, a sensor and a mechanism that is located inside the housing. The mechanism is coupled to the sensor to, in response to the detection of the feature by the sensor, generate a tension signal in the line without physically contacting a downhole structure.
