The Ultra-Short Four-Parameter Combination Logging Tool integrates telemetry, magnetic positioning, gamma, temperature, and pressure measurements into a single instrument, allowing multiple parameters to be logged with just one tool. The instrument uses a PIC microcontroller for intelligent control, with a simple circuit design that makes maintenance easy. Its mechanical structure is highly integrated and optimized, providing good sealing, ease of use, and maintenance. This design reduces the length of the instrument, improves its reliability, and expands its range of applications. The tool is primarily used for depth calibration, temperature testing, and wellbore pressure measurement during the logging process, providing valuable information for formation property analysis.
