AI Technical Summary
Existing methods for assessing the quality of sonic logging data lack unified evaluation standards, have low processing efficiency, are easily affected by human factors, cannot meet the needs of real-time logging in the field, and lack rapid quality control methods to reduce the uncertainty of data quality assessment results.
The frequency domain quality control method is adopted. By receiving full-wavelength acoustic data and performing time-frequency conversion, the target peak position, peak position and half-width at half-maximum are determined, the effective bandwidth and peak frequency are calculated, low-frequency threshold and high-frequency threshold are set, abnormal signals are detected, and quality assessment results are generated.
It enables automated quality assessment of sonic logging data, improves processing accuracy and convenience, provides more reliable data quality assurance, and is suitable for real-time detection and anomaly diagnosis in complex environments.
