The tools work at ambient temperature of 175°C, pressure of 140MPa. The tool O.D. is Φ73mm and suitable for deep well logging. The system consists of a surface system, and downhole logging tools. Tools could be run on either cable or memory logging modes.

1.Function

In memory mode，The ground collection box collects and processes signals from mud pressure sensors, hook load sensors , and winch sensors, and outputs the processed data to the laptop's software for record. In cable mode, the ground collection box collects downhole tool data uploaded via cable, and outputs the processed data to software for storage; The power supply box also provides the main power for downhole tools and auxiliary power  .
