Description
This series of logging tools is mainly designed to meet the requirements for borehole diameter measurement, capable of simultaneously measuring three parameters: average caliper, X-axis caliper, and Y-axis caliper.
The opening and retracting of the caliper arms can be controlled from the surface. The tool features stable mechanical performance and utilizes domestically advanced, first-class high-precision sensors for measurement, ensuring high accuracy.
Currently, it is widely used in coal field, coalbed methane, shale gas, hydrological, and radioactive uranium mine logging.
