The A-One Oil Depth Time Recorder is a professional tool used to record and log the relationship between depth and time during downhole operations. It collects and processes downhole sensor data to achieve real-time monitoring and recording of depth changes during drilling or logging, providing support for subsequent data analysis and engineering decision-making.
It is an important component of the oil logging system. The main function is to record the depth and time information of downhole tools and store these data in the surface system. It is usually used in conjunction with winch systems, tension sensors, encoders and other equipment. By measuring parameters such as the tension of the winch rope and the rotation Angle of the winch drum, the depth position of the underground instruments can be calculated.
Features of Depth Time Recorder
