Abstract
The present invention belongs to the field of geologic survey, and particularly relates to a real-time calibration method and system of acoustic logging data while drilling for precise navigation of deep oil and gas, aiming to solve a problem of inability to automatically identify stratum boundaries to adapt to geology at various different depths in an existing drilling process. The method of the present invention includes: acquiring standardized acoustic parameter data while drilling; acquiring time-depth relationship of historical acoustic curve data of drilled wells, and current actual drilling time-depth relationship; performing interpolation based on the current actual drilling time-depth relationship, to acquire interpolated current actual drilling time-depth relationship; correcting the interpolated current actual drilling time-depth relationship; and completing current precise depth correction based on the current actual drilling acoustic curve.
