Quality Control and Application of XMAC-F1 Dipole Share Wave Reflection Imaging Logging Data

The cross dipole share wave reflection imaging logging technology is the extended application of XMAC-F1 instrument. The geological information outside the borehole can be obtained by analyzing the share wave reflection imaging data. Qualified dipole acoustic wave data is the key factor to obtain accurate share wave reflection imaging processing results. In order to ensure the accuracy and reliability of acoustic data, combined with the principle of XMAC-F1 data acquisition, this paper expounds that the measuring rate of the instrument, the neutrality of the instrument during logging, the azimuth data measured by the instrument, and the rotation of the instrument are important factors affecting the quality control of dipole acoustic wave, and analyzes the influence of different factor values on the processing results. The key points of quality control of dipole acoustic logging data, such as pre-test inspection, logging data monitoring, measuring rate control, instrument rotation control and instrument azimuth quality control are put forward. The practical application of the data quality control method has achieved obvious results, which effectively solves the quality problem of the original dipole acoustic data, and has a good application prospect.
