AI Technical Summary
Traditional downhole gamma ray inspection tools lack azimuthal resolution due to collimated sources and detectors, making it challenging to effectively inspect multistring wellbores with multiple layers, such as cement and casing, which results in incomplete data acquisition and increased operational costs.
A downhole logging system with a gamma ray source and detector collimator that rotates synchronously to direct and receive radiation, allowing for azimuthal scanning and data acquisition, enabling the identification of defects in cement layers behind multiple layers through synchronized rotation and signal processing techniques.
The system provides enhanced azimuthal sensitivity and reduced acquisition time by obtaining comprehensive data sets, improving the detection of defects and wellbore characteristics in multistring completions, thereby increasing inspection efficiency and accuracy.
