The invention provides a method and device for interpreting micro-logging information and acoustic logging information in a united mode. The method includes the steps of (1) collecting the micro-logging information, and carrying out first-break picking on the micro-logging information to generate micro-logging first-break time; (2) collecting the near-surface acoustic logging information, and extracting acoustic logging speed data; (3) carrying out offset distance depth correction on the micro-logging first-break time to generate micro-logging time-depth relation data; (4) generating acoustic logging time-depth relation data according to the micro-logging time-depth relation data and the acoustic logging speed data; (5) merging the micro-logging time-depth relation data and the acoustic logging time-depth relation data to generate combined time-depth relation data; (6) carrying out horizon interpreting according to the combined time-depth relation data to generate horizon interpreting results. According to the method and device, the micro-logging information is used as a base, the acoustic logging information is converted into an accumulated time-depth relation and combined with the micro-logging information to interpret a near-surface model, the accuracy of surface-layer surveying information is effectively improved, and the investigation depth is effectively increased.
